Rylan Why Are Your Big Friends Here

 Rylan Why Are Your Big Friends Here?

Laura Lex talks to Ron about new glasses and performing stand up in them

Laura: Hello and welcome to another episode of Lex Education. It's the comedy science podcast where comedian me, Laura Lex, tries to learn science from her nerdy younger brother, Ron.

Ron: Hello, I'm Ron.

Laura: That is Ron. Hi, Ron. How are you?

Ron: Mmm, good, thanks. How are you?

Laura: Bad, thanks.

Ron: New, uh, glasses.

Laura: I do have new glasses. Yeah.

Ron: M. I wanted a bit like Ned Flanders glasses.

Laura: Oh, do you reckon? I feel a little bit like, um, the Nazis in Indiana Jones because they're more rounded than I'm used to. Not because I'm a terrible person. I think I might be a terrible person, but that's separate. Um, I wanted something with a bit less frame.

Ron: Fair. Big frames have been in for quite a while, so I can see them being out soon.

Laura: I was tired of lots of frame and I can see a world where I might end up wearing them for projects a bit more. Um, I don't like wearing them on stage. Not because I'm vain, but because the way the, like, show lights go through the glasses, you get glare on them, no matter if you get the anti glare or whatever. And I can't see the audience as well. And I don't like that. Um, but I've also, I think performing stand up in your glasses really changes the way your facial expressions hit. Because obviously things can be seen and can't be seen that are slightly different. And so I think you sort of have to practise in them and out of them.

Ron: Okay.

Laura: Okay. Well, that's the end of that bit of the conversation. Um.

Ron: I don't know, you started rambling.

Laura: About glasses and I say, to be honest, good episode.

Ron is taking the neffs to see some rugby tomorrow in Bristol

Um, where are you going tomorrow? On a train?

Ron: Um, I'm taking the neffs to go see some rugby in glauces, though.

Laura: Oh, wow, that's a trip. Are you meeting the nephs there?

Ron: Um, they're actually driving into Bristol and then getting the train from here. So.

Laura: With you?

Ron: Yeah. And their parents are going too.

Laura: Oh, okay. I thought you were just solo wrangling some nephs.

Ron: No, I've solo wrangled one of the nephs before for a bit of rugby, but that was in Bristol.

Laura: They're pretty easy to wrangle these days. They're full, like automated teens.

Ron: They're really placid.

Laura: Yeah, they're also like. They're in that big and tired bit of teen life.

Ron: Only one of them's big.

Laura: They're both bigger than me.

Ron: Yeah.

Laura: Time for a really big drink run. This is the worst.

Ron: I'm hungover.

Laura: Oh, is that what's wrong with you? Where Were you last night?

Ron: I just went to the pub. We met my friend Aiden for a pint before he went to play football. He plays football every Friday. It's psychotic. Um, and, uh, his football was at 7. And I sat down at the pub. Um, another friend, sports, uh, correspondent Max, was there. Um, and, um, Max had a. Max and Aiden had a pint. I got there a bit later than them, and then, um, they were like, oh, you didn't buy a drink, Ron? And I was like, well, I didn't know if we were staying longer than seven when Aiden goes to football.

Laura: Yeah.

Ron: Um, because, like, I'm not really interested in, um, you know, just having, like, one pint that's not worth the calories or the money, you know? But if we're having, like, an evening at the pub, then I'll happily indulge. Um, and then they talked me into getting a drink, so I forced Max to stay at the pub with me all evening.

Laura: Nice.

Ron: Yeah. Then I went home. It's the, um. I was drunker than I thought I'd be because it's the first time I've browned out in a while. But I came back.

Laura: What the hell is browned out?

Ron: It's when you haven't blacked out. But it is.

Laura: You meant you shat yourself?

Ron: No, no, no, no, no, no.

Laura: I thought you meant you just pooped your pants. Cause you were so drunk.

Ron: No, Laura, if that's what that meant, then I'd never be saying it's been a while. Um, no, no, no, no, no. Just. Ah. Yeah.

Laura: Would you admit to that on the podcast if you had browned out in the lex education

00:05:00

Laura: sense?

Ron: Um, I think. I think I'd need more than 10 hours to admit it. I probably. I might admit it next week.

Laura: Yeah. Okay. Yeah, yeah.

Ron: I'd still be marinating in shame and some brown. Um, no, no. Yeah, because, um, I got back, I was very drunk. Um, apparently, uh, because I woke up, I'd prepped all of the episodes for this morning, apart from, like, I had to do, like, 10 minutes this morning. Um, I'd done the washing up, and I'd watched one and a half episodes of Succession that I need to rewatch.

Laura: Yeah, I want to watch Succession.

Ron: It's good.

Laura: Yeah. I think we watched episode one, and Tom wasn't as into it as me, and then I forgot it existed until this moment.

Ron: There's not enough, like, bright flashing lights, and nobody's called, like, Succession, man.

Laura: It's not his style. We really struggle with stuff that we both like. Because I have no attention span. And he's. He would watch lots of different things, really. But I think for him, he's like, doesn't want to get too attached to a TV show because there might only be three episodes of it I'm interested in.

Ron: That's fair. You're a nightmare.

Laura: I am. Um, the fun thing about this episode, Ron, is I haven't started editing it yet, which is giving me the creeping chills every time I think about it. But it's fine because it doesn't need editing until tomorrow night. Um, and all I have to do between now and then is pack for me and a three year old to go to New Zealand for a month, do two gigs, pick up our, uh, sister from the airport, and stop having panic attacks so I can edit it in that time. Yeah, this might be the most unedited episode you've ever listened to that's about to play. You might be hearing some warts and all. Lex education.

Ron hit a deer on his drive home yesterday and now his car is broken

Ron: Let's not pretend it's anything other than warts. Warts.

Laura: 99.9% warts.

Ron: Um, it's like a Ferrero Roche instead of nutty bits.

Laura: I've just had such a terrible week, and then yesterday I was doing a gig, and then I was on my way home from the gig, and just to put the, like, shitty crown on my browned out week, I. I, uh, hit a dead deer on my drive home and I, uh, fucked up my car.

Ron: Was it dead when you hit it?

Laura: Yeah, it was already dead and in the road, so I didn't see it. And then it was high even though it was dead. And, uh, I've broken my car.

Ron: What happened to the car?

Laura: Well, it smacked a massive fucking deer, so it's broken. Basically. It's physics, isn't it? If you're going at 60 miles an hour and you smack into the corpse of a deer, then the bits of your car that are less, uh, strong than a deer will break. Oh. It's also disgusting last night because there were lots of bits of deer on the front of my car. And then by the time I got home, like, Mackie was out barking. And when I went out, there was just a fox sitting there just licking all the deer off my car.

Ron: God, when it rains, it pours for you.

Laura: I know. I just live in, like, a horrible episode of BoJack Horseman. Dog with her head through the gate, screaming at a fox that's just. Oh, God. And now I don't have a car, so it's all stressful. More getting to the Airport. And I was going to give my houseplants to Danny to look after while I'm away, but now I can't get them there, so Tom's definitely going to kill them.

Ron: You'd give your house plants to someone even though Tom's gonna be at home?

Laura: Yeah. I can't go away for, like, a weekend and Tom won't forget them.

Ron: He's useless.

Laura: Yes. This is why I have panic attacks every other day. Yeah, he's actually great. He's great at calming me down. He can't do practical things, but he can really make me feel better while I do the practical things. And that works for us. But then it means. Like this last week, he's been away for seven days and, um, it's coincided with me turning into a cartoon character having a bad day. And, um, So I.

Ron: You're Mr. Frumble.

Laura: I am. I'm staring down the barrel of a month without Mackie and I'm genuinely. I know it sounds pathetic, but I just don't know how to cope without her for a month.

Ron: And that fringe just is not growing out.

Laura: No, because I had it cut again yesterday, Ron.

Ron: Did you? Yes. Why did you ask them to do the same thing?

Laura: I didn't. This bit of hair looks much better. The side looks better. Obviously it looks

00:10:00

Laura: bad now, but that's because I've just woken up and I have my snooze band on overnight. But the fringe is a bit better.

Ron: Can't tell.

Laura: Well, I hate you. Hey, listen to this episode. I don't know what it is or even if it's edited. I don't know. Lesson 150, Ron.

Ron: That's mad.

Laura: Yeah, we should have stopped a really long time ago.

Ron: When you factor in the Patreon bollocks as well.

Laura: Yeah.

Ron: Why is my laptop not charging?

Laura: How many Patreon things have we done?

Ron: Bit?

Laura: We've recorded 46 patreons, so we're almost.

Ron: At 200 total plus lives.

Laura: We probably. We are at 200 totals if you include lives.

Ron: Hang on.

Laura: What are you doing?

Ron: Texting friend of the podcast, Noah, about Baleen Wales.

Laura: Whoa. What about them?

Ron: Well, I was just reading an article about them in the short recording break that we did. Um, and, uh, it just the. The evolutionary leap to go from what they were before to filter feeding. It just. It feels like any halfway house between those things. How did. How. How could that be a surviving creature?

Laura: Maybe it got a load of reeds stuck in its mouth and the filtering was just really working. Not that, um, this is why you Texted it to Noah instead of talking to me about it.

Ron: I actually stopped you from talking so I could finish my conversation with someone that understands.

Ron: We're on our third record of the afternoon. Now we've been recording for two hours

Laura: It's amazing how much your Persona's changed. Now Meg has gone.

Ron: What do you mean?

Laura: You were all joking, messing about. Now Meg's not here and you're like, no.

Ron: Now we've been recording for two hours. We're on our third record of the afternoon.

Laura: Yeah, it's long.

Ron: Yeah, it is long. And, oh, uh, you walked into the quiz and you're like, that's gonna be a bloodbath. Do you know what's gonna be a bloodbath? Laura? Do you know what's actually gonna be a bloodbath?

Laura: Um, this lesson.

Ron: Yeah, because you know what we're covering, Laura, after being recording for two hours, doing almost 200, well over 200 episodes.

Laura: What is it?

Ron: I think at least three of them have been on this.

Laura: M down.

Ron: No, it's chemistry. Oh.

Laura: Uh, was that knock down?

Ron: No, that was physics.

Laura: Oh. Uh, um, what we're doing then. Smoles, Smalls.

Ron: Moles.

Laura: Moles. No, no, I can't go back there.

Ron: No, Ron, we have to cover moles again.

Laura: No, not today, Ron. I will not. I cannot. I shall not. A dozen carbon twelves.

Ron: No, that's not it though, is it?

Laura: Isn't it? One gramme of 12 grammes of 12. What is it? I don't want to. I've got this microfiber cloth for cleaning my screen.

Ron: Yep. And you don't like touching it in the winter? Uh, yeah, yeah, you talked about that recently. Sounds horrible.

Laura: If that was a snack, it would sound delicious. But that's meant to be a cloth.

Ron: That whole arrangement there just looks marvellously over Engineered.

Laura: Sandstorm. Um, Scandinavian.

Ron: So, Laura. 3. 1.2amount of substance.

Laura: Okay, maybe this is the day it goes in.

Ron: We could. Should we do something else?

Laura: But then this is just loitering a little mole around the corner.

Ron: Yeah, I mean, I, um. I don't. Yeah. But I just really can't be fucked to sort of push you uphill on it, you know?

Laura: You have to get fucked, Ron.

Ron: But why do I have to be the one all the time?

Laura: Because I do try my best, but I don't think you understand how much I am trying.

00:15:00

Laura: Should we zhuzh it? How can we zhuzh it?

Ron: It's not very zhuzhable, to be honest.

Laura: Mole, we're gonna have to zhuzh more because a level is all gonna be hard, cruddy work if we don't zhuzh more of it.

Ron: Uh, but we loved the biology. No shushing required.

Laura: No, the last biology was dry.

Ron: The last biology was great. What are you talking about? We were covering Esther's.

Laura says Fame and Sorrowful are conflated

All right, Laura, you ready?

Laura: Yeah, I'm ready. Pepped Zushy. Ready to go. Shame. Um, that song really called Fame.

Ron: Yeah. Fame makes man think things over.

Laura: Shame.

Ron: Yeah.

Laura: Makes a man think things over.

Ron: What you've conflated there, I think, is Fame being one of David Bowie's more famous songs. And then our father's favourite, David Bowie, which is Sorrowful. And I think you've combined the two.

Laura: I thought that was the Kinks.

Ron: Is that with your long blonde hair and your eyes were blue the only thing I ever got from you was sorrow. It's, uh, not originally David Bowie, but he does do a good version and.

Laura: It'S Our father's the McCoys. It was by originally.

Ron: Your net.

Laura: Oh, no, maybe it was the. Oh, yeah.

Ron: Sorrow.

Laura: And then it was covered by the Merseys.

1. Relative atomic mass and relative molecular mass. 2. Molecular mass. 3. Atomic weights

Ron: Anyway, um, so, Laura, the first thing that we're just gonna cover off, just do a quick little refresher. Um. 3.1.2.1. Relative atomic mass and relative molecular mass.

Laura: Relative atomic mass. Relative.

Ron: Uh.

Laura: M. Molecular mass.

Ron: Molecular mass. Yes.

Laura: Molecular mass. That, uh, is where you go for absolution. But you share a wafer.

Ron: Um, Laura, why do we have to use terms like relative atomic mass? Why don't we just use kilogrammes?

Laura: A very loud motorbike.

Ron: Yeah, I could hear it a bit. Um, not as loud as your dog. Seagulls or child, though, so I think we can.

Laura: That's not my dog, actually. That's a neighbor's dog. Um. Uh, and the child's gone out. Um, because. They all have different masses, Ron. Because of neutrons.

Ron: Yep. But, you know, a watermelon and a dodo have different. Why. Why is Ice Age popping into my head?

Laura: They have different masses, but the animation has not stood the test of time. You know how Monsters Inc. And Shrek and stuff kind of look. Okay. Because they picked topics that you could fudge and Toy Story and stuff. Yeah. Ice Age looks bad.

Ron: Uh, well, I've always just thought Toy Story was such a stroke of genius because they're all made of plastic, so they don't have to move in, like, a very human way. Same with cars, I guess.

Laura: Yeah. Yeah. They really knew the limitations of their technology. I remember dad talking about the amazingness of Sully's hair a lot when Monsters Inc.

Ron: Came out. Yeah. Talking about how long it would take to render each of the Frames. And I didn't know what rendering frames was.

Laura: No, but he seemed so impressed with Sully's hair.

Ron: But you think when he was born, like, he was probably watching fucking Cecil B DeMille and stuff.

Laura: Dad is still, to this day, scared of trains coming towards him. You can distract that man for a good 20 minutes by flicking a book really fast and a man dances.

Ron: Sorry, dad. Um.

Laura: Yeah, we shouldn't slag him off. Of all the people that we're related to, he's the most likely to be listening to this.

Ron: Yeah. In his own way, he is the most supportive of this endeavour.

Laura: Yeah. Um, we should get him back on the show.

Ron: Yeah. Agony dad was. Was beloved.

Laura: Yeah. Thing is, it was just. It was really hard collecting people's, um, problems. I don't think our listeners have any problems. They're all happy souls. I think it was better when we had a subject to do with him.

Ron: Yeah, well, we could. We could mix

00:20:00

Ron: and match. We could go to the Discord rather than just to.

Laura: But this is why our listenership is dwindling, Ron, because everything is slowly being pulled into our dank underworld cave. We don't tell anybody new that we're doing the podcast.

Ron: Yeah, but one of the listeners did just ask me for recommendations on places to go in Bristol and I typed out five paragraphs.

Laura: And yet you won't do one. One post a week to tell the wider world that we do this podcast. We waste so many hours on this.

Ron: I have fun.

Laura: Yeah. And I'm here.

Ron: Anyway, as I was saying.

We rewatched Shrek when I was at yours recently

Actually, no, my last point on the tangent is when we rewatched Shrek when I was at yours recently. I think they do a pretty good job of, um. Of like, hiding it as well sometimes. But what I really noticed when watching that is that all of the scenes take place just kind of on a flat plane with a background like M. They're never, like, integrated into the environment that they're in. In that.

Laura: Smart.

Ron: Um. Well, no, it looks bad. Oh, I wasn't. That wasn't a compliment.

Laura: I've got to be honest, I wasn't really listening to what you were talking about. No, Laura, I was replying to confirm. I will go on Jessica Knappett's podcast.

Ron: Oh, I like Jessica Nappett.

Laura: Wow.

Ron: She was in a show called Drifters. Yeah, that friend of the podcast Noah and I watched when we were at uni.

Laura: Oh.

Ron: Um. And I think the final scene of that is she's at her ex's wedding and she has sex with someone in the toilet. And then as she's speaking to the mother of the bride, his cum falls down her leg.

Laura: Oh, wow. Yeah, well, it does happen.

Ron: Delayed seepage, she called it. Um, anyway, yes, it's funny.

So, relative atomic mass. We boil it down and we use these relative atomic masses

Laura: So, relative atomic mass.

Ron: No, I wanted to say circling back to the original ice age point.

Laura: Oh.

Ron: A watermelon and a dodo, uh, weigh different things, but we can measure them both with kilogrammes. So why would a variable number of neutrons mean we couldn't measure an atom in kilogrammes?

Laura: They're too small.

Ron: Ron, that's the answer we were looking for. Yes, it would be vastly unwieldy. Um, what would you have to use maybe, to represent those numbers?

Laura: Standard form.

Ron: Standard form, yeah. And, um, as we all know, we have.

Laura: So. So is the difference between, like, the smallest atom and the biggest atom? Insane. Um, relatively speaking.

Ron: Well, relatively speaking, in terms of weight, one is about. Was it like 200 times bigger or something? Maybe 150. In terms of, like, diameter. I actually don't know. Um, yeah, so hydrogen, the weight is. The relative atomic mass is 1. Lorentzium. Actually, no, we've got one here called organison, um, which I think is in the theoretical bit, um, or at least the unnatural bit. 294.

Laura: Yeah. So, yeah, yeah.

Ron: Almost 300 times bigger than a, uh, hydrogen. Um, Yeah. I don't know what the diameters on those would be compared to each other. I imagine maybe more than that. I don't know. Um, so, yeah, so we have. So we. We boil it down and we use these relative atomic masses. Laura, so you mentioned carbon 12 earlier. What are you doing? You're looking at something.

Laura: Yes, I was checking how much bigger than a person a blue whale was so that I could have a think about how big these atoms are.

Ron: Laura, you've never seen a blue whale.

Laura: I have. In the Natural History Museum.

Ron: Touche.

Laura: But a blue whale is about 2,700 times bigger than a human. So now I've got some scale that the biggest atom. M. What about a kangaroo? And the smallest one is an ant?

Ron: No, a kangaroo's much bigger to an ant than a blue whale is to us.

Laura: No. Okay. Um. Like a pencil eraser.

Ron: Compared to what?

Laura: A kangaroo.

Ron: Why are we using a kangaroo?

Laura: They're just memorable, aren't they?

Ron: I've heard before that supposedly with atoms, if the nucleus was a

00:25:00

Ron: football, sort of the shells, and that would be the size of Wembley Stadium.

Laura: Oh, okay.

Ron: Does that help?

Laura: Well, uh, maybe that's hydrogen. But then I just wanted to think about organison.

Ron: Yeah, but we're Just talking about the nucleus there. We're not talking about the empty space around it.

Laura: Yeah.

Ron: Does your pencil eraser cankery visualisation help?

Laura: Well, yeah.

Ron: Um. Right, uh, where were we? So you mentioned carbon 12 earlier, Laura. Where does carbon 12 fit into all of this?

Laura: Um, that is the one that we use to work out moles.

Ron: And how did we do that?

Laura: 12 grammes of carbon 12 equals one mole.

Ron: Uh, well, yeah, yeah, yeah, that's true. The number of atoms there. That's a mole. Um, cool. So what we're going to do is we are going to just double check kind of your memory of, um, some of this stuff. Okay.

Let's go back to the periodic table then. What are the numbers on there

So, Laura, could you please tell me the relative mass of water?

Laura: No.

Ron: Presuming the most abundant isotopes.

Laura: Jellyfish, mongrel, Spanish frittatas.

Ron: Apply yourself.

Laura: Apply yourself. I don't even know where to start, ron. Water is H2O.

Ron: Yep. Let's go back to the periodic table then.

Laura: Yes. Okay. H2O.

Ron: Let's take a look at oxygen. The O of H2O.

Laura: Yep.

Ron: What are the numbers on there?

Laura: 8 and 16.

Ron: Okay. What does the 8 represent?

Laura: 8 is the atomic number, 16 is the atomic weight.

Ron: Do we call. Yep. What's. So you've got the atomic number. And then what's the other name that we've got for the other number instead of atomic weight?

Laura: Mass.

Ron: Yeah, we call it the mass number.

Laura: Don'T we don't have my periodic table.

Ron: Yes, but we've got to apply previous knowledge, not just take every day like the fucking guy from Memento. Uh, just reading things that are written down, trying to piece together your life.

Laura: I don't know why you always use Memento when, you know, I haven't seen it, but I have seen 50 first dates.

Ron: Because that has a happy ending.

Laura: It does have a happy ending.

Ron: That's what I said. Exactly. So I don't want to reference that. I want to reference Grim Memento.

Laura: Does that not end happily?

Ron: I can't remember. That's the ironic thing. Laura.

Laura: Yeah?

Ron: Don't scratch your back with big scissors.

Laura: I got a real itchy shoulder blade.

Ron: Ugh.

Laura: Uh, what's wrong with that? They're closed.

Ron: Yeah, it's just a bit gross.

Laura: You think the weirdest things are gross?

Ron: Ah. Uh, do you know what I think one of the grossest things in the world is? You know, like, um, when you're at school and they'd have just like two bowls of scissors and one of them would be the red ones for cool kids, and the other ones would be the Green and yellow ones, but you actually kind of wanted to use those because green and yellow was cooler. But unfortunately you weren't left handed so you couldn't. And then you'd. So you take some of the scissors out of the bowl that you could use. And then because it was school and sometimes things were broken, like the blades would be curved and then they kind of like yak against each other. Oh, uh.

Laura: Yep.

Ron: Look, you're not getting on board, but I think I've described a really universal experience.

Laura: I think that that needs to go in your stand up set that you're.

Ron: Writing about the two bowls of scissors.

Laura: Yeah, yeah, yeah.

Ron has a new bit that he tried out last night

I've got a new bit that I tried out last night that got a little bit of something that I think I could write more on.

Ron: Was it my tendrils joke?

Laura: It wasn't. No. That was very good though. I'm sorry I didn't reply to that earlier. I can't remember what I was doing, but I was busy.

Ron: Um, what do you want to tell us about it?

Laura: Well, here's the bit, Ron. And I don't know whether, like how big it can go or whether it is just this sort of line, but how.

00:30:00

Laura: I think being really into ghosts is the perfect hobby because people that uh, really believe in ghosts see ghosts and people that don't believe in ghosts never see them. And I just wish more hobbies could be like that. Like if I just didn't believe in football, it just wouldn't exist for me.

Ron: Yeah, that's very funny. Yeah, that's good.

Laura: I, uh, don't know whether there's more to that or is it all done once I've revealed the, like, football's annoying and fucks up infrastructure? I don't know, there's something in it anyway.

Ron: Yeah, it's, it's certainly a good observation.

Laura: Tried it out last night. I've also, I've tried it out three times now and it's worked every time. A bit about how I think lions have absolutely smashed society because from the woman's perspective, you hang out with like 15 of your mates and then every now and again a bloke comes over and has sex with you. Great. But he also has sex with everybody. So you can chat about how it was between all of you and then he just goes and sits over, uh, there in case you need anything and he can just have a look at 15 women that he can shag anytime he wants. But crucially, from our perspective, he's over there. Perfect.

Ron: Yeah. You gonna revive your lions bit from One of your shows ages ago.

Laura: No, but I was thinking, you know, Lions 2.0 maybe. It's going in the tour for next year.

Ron: Yeah. Fun.

Laura: I like animal bits. I think they're fun.

Ron: No, I did start writing my page of stand up. Got a bit about how, um, there's a weird kid and because I wanted to be an undertaker. But what's maybe weirder about that is how keen my mum was to make me an undertaker.

Laura: Didn't you do your work experience at an undertaker?

Ron: No. Like, this is the thing, like, seven years in advance. Mum set that up for me because she was so keen. But obviously by the time it actually rolled around, I didn't want to be an undertaker anymore.

Laura: We all just thought you'd be really good at it. You were very quiet and solemn. Good at digging.

Ron: Yeah, the writing was on the wall.

So what's the most common isotope of hydrogen? Oh, I'm not sure

Anyway, um, so, yeah, we've got the atomic number.

Laura: Yeah. I've leapt ahead here on. So I've got O has the atomic mass of 16.

Ron: Yes.

Laura: H is 1.008. So I've put 2.016. Because there's two hydrogens.

Ron: Well, I did say assume the most abundant isotope, didn't I?

Laura: So that's correct.

Ron: What's an isotope? Laura?

Laura: An isotope is a variable number of neutrons in an atom.

Ron: Yep.

Laura: I never know how to say that sentence. I know what I mean, but I don't know how to say it.

Ron: I know that you know what you mean as well. Um, okay, so what's the most common isotope of hydrogen?

Laura: Oh, I'm not sure.

Ron: Well, if you look at the mass number, what do you think? Because that's an average, isn't it?

Laura: Yeah. 1.008.

Ron: Can it be 1.008? Uh, one hydrogen be that.

Laura: No, because a neutron's always one.

Ron: Yep. And a proton's always one.

Laura: Oh, okay. So one is the most abundant.

Ron: One's the most common isotope. Yeah.

Laura: So, so just two.

Ron: Yeah. Two from the hydrogens, one from the oxygen. Absolutely.

Laura: So in order to guess the most abundant, blah, blah, blah, you just round it up, basically. So, like, sodium would be 23, potassium would be 39.

Ron: We don't round it up.

Laura: You round it to the nearest whole number.

Ron: Yeah, exactly.

Laura: Okay.

Ron: Okay. Um, we're gonna go to a little bit of, um, history repeating, uh, just a little bit of, uh, nomenclature for sort of writing down chemical formulas and stuff. Laura.

Okay, so I want you to calculate the relative mass of ammonium sulphate

Okay, so I want you to calculate the relative mass of ammonium sulphate. Okay.

Laura: Why did we just do that for water and then sit on Our butts.

Ron: What do you mean?

Laura: Why did we just. What was the point of doing that with water?

Ron: To check you could do it? Because. Do you remember when I first asked you if you could do it? You were.

Laura: But what did I just do? 18. Is that how much water waste?

Ron: That's just the relative atomic mass.

Laura: Okay.

Ron: Relative molecular mass. Um, yeah, but I know that when I introduce these concepts to you, you tend to sort of shit and say you can't do it, so

00:35:00

Ron: it's better to get you to do it.

Laura: I just don't know what the words mean.

Ron: That is more and more apparent every day, which is why we have to run through them. Um, so we're going to work out the relative mass of ammonium sulphate. Okay.

Laura: Okay.

Ron: So ammonium sulphate is a sulphate ion, which has a negative charge of minus 2. Um, ammonium ion, which is an NH4 molecule that has a relative charge of plus 1. So for ammonium sulphate to be sort of a distinct thing, you need two of the ammoniums and one of the sulphates. Okay.

Laura: Okay.

Ron: The way that we write this, so that, uh, it's not hugely, uh, wordy when we're writing it down or long, um, is we. We borrow a bit from maths, from a bit of bodmas. So what we're going to do is we're going to have NH4, which is the ammonium, and we're going to put that in brackets, okay?

Laura: Yep.

Ron: And then similar to how when you've got, like, H2O and you do the little two at the bottom, we're going to put a two at the bottom outside those brackets. Okay?

Laura: Yeah.

Ron: And then. Then we just need the sulphate ion. So that's so four. So with a little four as well.

Laura: Right, okay.

Ron: So can you calculate, please, the relative mass of ammonium sulphate?

Laura: Why don't you just do 2 NH4?

Ron: Because it's all part of one thing. So if you put a big two at the beginning, that would then, like times two to everything. Whereas we're saying just two of this bit.

Laura: Okay. So N, that is 14. So we'll call that 28. H is 1. Four H's times two is eight. So we're talking 36 in the NH4s. Ah, is there, uh, 32 plus O we already knew was 1664. So that's 96. So 130. One hundred and thirty two. Sorry.

Ron: One hundred and thirty two. Absolutely. Well done.

Laura: And that's a mole.

Ron: No, that's the relative mass of ammonium sulphate.

Laura: Oh, look at me. Just calculating the relative mass of ammonium sulphate on a Tuesday afternoon.

Ron: Yeah, and then asking if it was a mole. Um.

Laura: Look, can you please just focus on the positives for once? Ron, you are always negative.

Ron: That's not true. I've gotten a lot nicer to you.

Laura: No, I don't think you have. I was listening back to some early episodes, and I think you used to cajole. You used to zhuzh. You used to come with a bit of pep in your step, and now it's like you walk into it going, if you don't understand it from me droning it on, then there's no helping you.

Ron: That's not true. Think about the quiz we just did. I was really nice doing that.

Laura: Yeah, but there's no zhuzing.

Ron: Okay, okay.

Laura: Welcome to the zhuzh lesson.

Ron: We'll do another one. Okay, um, I just did that one.

Laura: Perfect. Why have I got to do it again?

Ron: No, because we'll do another one because we've got to get some zhuzh in there somehow.

Laura: How is that zhu jing? Repetition is not zhuzh.

The relative mass of calcium hydroxide is the password to the circus

Ron: We're gonna do, um, the relative mass of calcium hydroxide. But you know what? It's Rylan's calcium hydroxide.

Laura: Yeah, for his bones, maybe. Calcium hydroxide, then. Yeah, ca.

Ron: So, hang on. I'll let you work this out. Um, calcium, when it's an ion, has a charge of two plus. A hydroxide ion has a charge of one minus, even when it's at Rylan's house. What do you think the chemical formula of calcium hydroxide would be?

Laura: Um, CA bracket, H, O, Uh, close bracket, Small, too.

Ron: Perfect. Yeah. And then Rylan's got a bunch of his big friends around.

Laura: Big friends?

Ron: Yeah, his big friends.

Laura: Why are your big friends here? Uh, but for real, Ron, do you hear how much better this content is

00:40:00

Laura: now that Ryland's involved?

Ron: Um, and not only that, but the circus is in town. The password to the circus is the relative mass of Rylan's calcium hydroxide. So can you calculate that for me, please?

Laura: Yeah, I can. Um, 74 on.

Ron: Great. Now you can go to the circus.

Laura: Do you reckon they've got animals in the circus or just humans?

Ron: They do have animals in the circus.

Laura: Oh, no. We've got to get it shut down.

Ron: And we go to the circus. You, me, and Rylan. And we're walking through, and we say 74 to the man at the desk. That's the password for the circus. We walk in, and there he is. Petey Avogadro. In a big hat with, um, purple slippers.

Laura: Um, I'm loving this. I'm so engaged with the content.

Ron: And he gestures behind him. And do you know what we see?

Laura: Pedro Pascal?

Ron: No. Moles on balls and trapezes.

Laura: Oh, my goodness.

Ron: A mole jumps through a flaming hoop. Um, another mole is. Is on a seal, and the mole has a ball on his nose.

Laura: Whoa. Does the seal think the mole is a ball?

Ron: No. The mole's on a ball on the seal's nose. And there's a ball on the mole's nose.

Laura: Oh, I've got a book about a mole with a poop on its head.

Ron: Yeah, classic. Um, so, Laura, PT Avogadro.

Laura: Um, Avogadro. He's a very constant dude.

Ron: He is, but he's not. He's unstable. Yes. Um, the Avogadro constant number is, uh, a constant is the number of particles in a mole.

Laura: How many particles in your mole? Right.

Ron: Um. Uh, the moles, they're diving around.

Laura: Yep, yep. Here they go.

Ron: Moles. The number, though, the Avogadro's constant, that can be applied to electrons, atoms, molecules, ions, Formulas and equations. Right.

The concentration of a substance in solution is something that you'll have to calculate

Um, the only other bit that you need to know that we haven't gone through before in this bit, okay. Is, um, how we record substances. Um. Ah. Ah, yes. Right. Okay. This is where this becomes a thing. Okay, so, uh, you didn't read this.

Laura: Before the lesson, did you?

Ron: No, I didn't think we'd get this far.

Laura: You always underestimate me.

Ron: Yeah. Um, the concentration of a substance in solution, Laura, is something that you'll have to calculate quite a lot.

Laura: Concentration of a substance in solution.

Ron: Yes, um, we will. The. The unit that we use for this is moles per decimeter cubed.

Laura: Oh, that feels familiar.

Ron: So let's take some of that lovely ammonium sulphate. Actually, do you know what, Laura? Let's do a different one. Okay?

Laura: Yeah.

Ron: We're going to take. We're going to dissolve a kilo of potassium carbonate in a litre of water.

Laura: Right? A kilo of potassium carbonate in a litre of water.

Ron: Yep.

Laura: And is the seal jumping into this water?

Ron: No, the fans in the circus, they're drinking it. Rylan, spiked the punch.

Laura: Rylan, you scoundrel.

Ron: Yeah. Um, so we need to work out, Laura, to tell to the ambulance lady that's just arrived outside how much antidote to give everybody. Yeah, okay.

Laura: Well done for making her a lady, Ron. You're so progressive.

Ron: Yeah, um, I am. Um, okay, Laura, so the. The chemical formula for potassium carbonate is K2CO3.

Laura: Okay? So I need to work out the relative atomic mass first. Yep, got it.

Ron: And then from there we will work out.

Laura: Just keep them alive while I get on with this. 140. Ron.

00:45:00

Ron: Uh, you sure?

Laura: Uh, okay. No, that should be 39. 138.

Ron: Correct. Okay. Um, well, actually, because we're not using, um. Because this is the real world, we won't assume always just the most common isotope now, so we need to use the average value because we've got loads of them. Okay.

Laura: Okay, so.

Ron: M.

Laura: Doesn'T change it too much.

Ron: Well, on the scale of things, it might.

Laura: 138.22.

Ron: Perfect. Okay, cool. Right, and then Rylan's dissolved that in 10 litres of punch.

Laura: Okay, Rylan.

Ron: So now to get it in the concentration that we need, we need to convert it between the mass we've been given and the moleculum and the mole, uh, and the molecular mass that we've just worked out. Okay. Right, so all that you do to do this is we will divide the mass by the molar mass and that will tell us how many moles are in it.

Laura: So 10 litres?

Ron: Um. No, no, no. So we've got one kilogramme of our, uh, substance.

Laura: Right.

Ron: Which is a thousand grammes.

Laura: Yeah.

Ron: Okay, so basically we just divide a thousand by our relative mass.

Laura: 138.22.

Ron: Yeah. Divide a thousand by that.

Laura: Yeah.

Ron: And, uh.

Laura: Just talk me through. Exactly. So that makes. 7.23. 4843. Do we need the whole number?

Ron: Uh, no, we will go to two decimal places. That's what we've. We've calculated everything else in.

Laura: Okay, so 7.23. So just tell me again what we've done there. We've worked out the. We've got a kilo of this potassium carbonate, and the weight of an atom of a molecule of Potassium carbonate is 1.38. Is 138 to 22.

We need two particles of antidote to react with our poison

So is that us working out? What have we worked out there?

Ron: We've worked out the number of moles in a kilo.

Laura: Okay.

Ron: So AKA the number of particles. So the reason why this would be useful. So let's say that we, uh, uh, um, we know that for the antidote that we've got for this, um, poison that Rylan's trying to get everyone at the circus with, we might know that, um, for every one particle of our poison.

Laura: Mhm.

Ron: We need two particles of antidote to react with it.

Laura: Yeah.

Ron: Okay, so if we know. What was it? 7.2.

Laura: Yeah.

Ron: So if we know that, we've got 7.2 moles of poison. We know that we need 14.4 moles of antidote.

Laura: Yeah.

Ron: We could then, if we knew the relative mass of the antidote, work out how much weight of antidote we need, and then we'd know how much to put in, like the mixture of it that we're making.

Laura: Yeah. Maybe in a cake.

Ron: Definitely in a cake. How did you know?

Laura: Probably popcorn. Actually, that's what we need a hand.

Ron: Circus cake.

Laura: Circus cake, yes.

Ron: Yes.

Let's work out the relative mass of ammonium sulphate

Okay, so now we've got the number of moles and we've. We've.

Laura: So what? Just m. Want to understand this. Why did dividing the number of the kilo by the atomic weight give us the moles?

Ron: Because the way the relative atomic mass bit has come from us looking at 12 grammes of carbon. 12.

Laura: Yeah.

Ron: So it's all based around essentially how many, um, how many nuclear, uh, neutrons and protons and stuff make a gramme. That's kind of what it is.

Laura: Okay.

Ron: Um, it's all. It's all based around grammes. It was all calculated around grammes. So you can divide the number of grammes by molecular mass to convert between the two.

Laura: Okay.

Ron: Um, yeah.

00:50:00

Ron: Then we need to work out the concentration. So like I say we do that in moles per decimeter cubed. Um, we've. Rylan's dissolved this in 10 litres.

Laura: Yeah.

Ron: Um, nice and easy. One litre, uh, equals one decimeter cubed. Okay, so what's. What's the concentration?

Laura: We've got 10 decimeters cubed.

Ron: Yep. And we've got 7.2 moles.

Laura: So we've got 0.723 concentration moles per decimeter cubed.

Ron: Exactly. Okay. Um, let's take it to that place that I was talking about before. Let's say ammonium sulphate, the one that you already calculated the relative mass of it, um, is the antidote to this poison. And like I said before, for every one mole of poison, potassium, uh, carbonate, we need two moles of our ammonium sulphate. Okay.

Laura: Yeah.

Ron: How much ammonium sulphate do I need to go to the shop and buy.

Laura: Do I need to rework out the atomic weight of ammonium sulphate or can I use the rounded up one?

Ron: Uh, I'll tell you. It's 132.1.

Laura: Didn't want to be 0.1 out there. I'm trying to work out point. I'm trying to work out 1.44 moles per decimeter cubed of that.

Ron: Yep. Uh, not per decimeter cubed. We're just buying ammonium sulphate itself. So essentially, how much does. Yeah. 14.4 moles of ammonium sulphate weigh?

Laura: Ah, so I'd have to reverse engineer. No.

Ron: How much do you think one mole of ammonium sulphate weighs?

Laura: I don't know.

Ron: How much does 12 moles. How much does one mole of carbon 12 weigh?

Laura: 12.

Ron: Okay. What's the relative mass of carbon 12?

Laura: 12.

Ron: Yep. So one mole of ammonium sulphate, by that same logic, would weigh its relative mass.

Laura: Right. It's 132.

Ron: Yep. So what. How much does 14.4 weigh?

Laura: 132.1 times 14.4. 1902.24.

Ron: Okay, so we need 1.9 kilos of ammonium sulphate to stop rhylan from killing all of these people.

Laura: Yeah.

Ron: Talk to me.

This quiz teaches you what mole's relative atomic mass is

You seem just unhappy, I guess.

Laura: Like, I lose track of how you came to this conclusion with moles. A little bit. It all almost seems suspiciously easy.

Ron: It's one of those things where you have to be aware of the 12 grammes of carbon. 12 bit. That's how they calculated it. That's what it is. That's what the standard was based off of. But you don't need to be thinking about that when you're using it at all. Like, the. The boffins that made all of the science originally have done all of that brain work. And the reason why we use a system like relative mass is. Is because it makes it that easy to do. That's the whole point.

Laura: So whenever I'm dealing with a compound or a molecule, ammonium sulphate, hydrogen dioxide, whatever I can use, the relative atomic mass is. Whatever its relative atomic mass is. Is one mole of it.

Ron: Yeah, exactly. In Grammes.

Laura: In Grammes, yes. Okay.

Ron: It's almost like how, um, if you. If you're doing some geometry, like, to work out the area, um, of a circle. Circle is PI R squared.

00:55:00

Ron: Okay. Now, there's loads of interesting stuff on how they calculate PI. And it's a really long number, and, you know, it never repeats. And 3.14. Blah, blah, blah, blah, blah, blah, blah, blah. That's all really interesting, but all you need to know is that it's PI r squared. You don't really have to worry about what PI is.

Laura: Yeah. Ron, this is the best moles episode we've ever done.

Ron: Yeah.

Laura: Judging with Rylan was a genius stroke. And I think that that's it. Now it's gone in.

Ron: Okay, then I'll, uh, bring. I'll, uh, try and Z more.

Laura: I love Z, watch me lose this recording. Now.

Ron: Don't get. You know, we're not back to the glory days, but, um, it. It is better.

Laura: Yeah. Wow, I've got a real wheezy cough coming on.

Ron: Yeah, kind of like that penguin from Ghost Story 2.

Laura: I'm really worried. Shouldn't have done that. Uh, I'm really worried about this quiz, Ron, because in the intro to the episode we just recorded, we were talking about, how many years would we have to do this podcast before I could teach it to you? But this is literally, I think, the fourth time we've covered moles. And I felt like in the episode, I really got it. I was happy, I was content. And, uh, now I just, like, went through. I just sat down for, like, 15 minutes before the record to look at my notebook and to go, okay, you're gonna smash this. And I understand the making the wait bit. And. And then it all just flies out of my butthole again, and I cannot remember what any of it meant.

Ron: Well, the lesson did go better than previous moles, I think, because all you needed to know in GCSE was what a mole was.

Laura: And I think unless what a mole.

Ron: Wants, um, unless there's context, your brain tends to reject information like a bad kidney. And then you got a bit of context, um, in this episode. So, like, it did go better. But, yeah, it's whether you've maintained that I've, um. I've wrapped in a bit of what we're doing in biology into this quiz to give it even more context for you.

Laura: What are we doing in biology? Lipids.

Ron: Fat. Start the quiz now.

Laura: We are doing the quiz.

Quiz: What's the relative molecular weight of glycerol

Ron: Quiz, start. Um, what's the Mr. Of glycerol?

Laura: Mr. What the fuck is an Mr.

Ron: The relative molecular weight.

Laura: Oh, okay. Mr. Of glycerol. God, what's glycerol? My pen's not working. None of us stupid listeners bought me new gel pens this year. My pens have run out. God, I've become so dependent on other people's love. Glycerol. Okay, I've written glycerol down now, so I wonder if glycerol's somewhere in my book. One glycerol. Three fatty acids is glycerol. Triple C, five H3. Oh, is.

Ron: What.

Laura: Is that glycerol?

Ron: Yes.

Laura: Great. Uh, so three Cs. One, two, three, four, five Hs and three OHS. Gemini widgets. Okay, 12.01. So that's 36.03. Four. Five Hs is 5.04030. Is 48 plus three Hs is 3.024. So that's 51.024. Add, uh, them all together and what have you got? 36.03 plus 5.040

01:00:00

Laura: plus 51.024 equals 92.094.

Ron: Wonderful stuff, Laura. One mark for ye. Okay, Laura, that's what.

Laura: That's. And that's one mole, isn't it? That's a mole of glycerol.

Ron: No, that is the molecular relative. That's the molar mass of glycerol. If you had 92.09 grammes, that would be a mole of that.

Laura: God.

Ron: Okay, Laura, I have 150 grammes of a fatty acid that is four carbons long. How much glycerol in grammes do I need to turn it all into triglycerides?

Laura: I think, you know, I am lost.

Ron: What's a fatty acid? The vinegar they use on crisps. Pretty good.

Laura: Has that got lots of fat in it?

Ron: Crisps?

Laura: No, the vinegar.

Ron: No, it's just an acid. Oh.

Laura: Uh, well, I've been eating so many crisps. They're so thin. I thought I would be thin if I ate them.

Ron: I. The money I was gonna spend on a zic, I've just been spending on crisps.

Laura: My heart hurts all the time. Uh, what's the question, Ron?

Ron: I have 150 grammes of a fatty acid that is four carbons long. How much glycerol do I need to turn that into triglycerides completely?

Laura: Oh, God. I've got no idea what's happening.

Ron: What's. What's a triglyceride?

Laura: Is it a glycerol with three fatty acids?

Ron: Yep. Okay, so what information do you need to connect the dots?

Laura: Um, everything that would be in the dots. So what's a fatty acid?

Ron: Right. You should have drawings of fatty acids. I've asked you to draw them.

Laura: Great.

Ron: It would have been in the episode where we talked about glycerol.

Ron, there's nothing labelled fatty acid on this page

Laura: Ron, I'm looking at the notes, but there's nothing labelled fatty acid.

Ron: Okay. Do you want to show me what is there? Maybe you've drawn it, but not labelled it.

Laura: Is there anything on this page?

Ron: Hang on. It's not. It's not in focus. It's hard to see. Yep. That's a fatty acid there. There's a drawing of it. Yeah.

Laura: Fabulous. I'm going to label that fatty acid.

Ron: So you can see that it's a lipid tail fat. And then on the end of it is A carboxyl group. The acid part. Right, Carboxylic acid.

Laura: Right.

Ron: Okay, so you have 150grammes of fatty acid. That's four carbons long. We need to know how much glycerol in grammes. We need to turn that, uh, into triglycerides. Completed. We already know that it takes three of these fatty acids to react with one glycerol. Okay, we have the molar mass of glycerol.

Laura: Uh, 92.

Ron: Yep. What do you think? Maybe we might need to know about the fatty acid.

Laura: How much they weigh?

Ron: Yes.

Laura: So which bit is the fatty acid?

Ron: The whole thing's the fatty acid. But the one that you've got 150 grammes on is only four carbons long.

Laura: So how many H's is that?

Ron: Well, I need you to work that out. At some point, you must start applying prior knowledge.

Laura: What do I draw the carboxyl group on?

Ron: Is it part of the molecule?

Laura: I don't know.

Ron: What would it. Would it be what it is if it didn't have all the bits of it?

Laura: So what I just don't understand. That's got five carbons.

Ron: Yes. And we need four, which is one less than five.

Laura: Oh, fuck. It makes me feel a bit sick doing this.

Ron: It is hard to look at yourself in the mirror sometimes. Sometimes.

Laura: Four Cs.

Ron: Why didn't you draw it out?

Laura: Uh. Oh, Shut up. I hate you.

Ron: I think you hate yourself.

Laura: Yeah, but since when has our family ever solved that problem rather than just shunting those feelings onto the closest person to them? Right. 88.104.

Ron: Explain.

Laura: That's the weight of the fatty acid.

Ron: Explain.

Laura: Four Cs.

Ron: Yeah.

Laura: 2, 3, 4, 5, 6, 7, 8 Hs and 2 Os.

Ron: It's different to the number I got. Wait, say your number again.

Laura: 88.104.

Ron: Yeah, it's different to the number I got.

Laura: What did you get?

Ron: Um, I got 91.1278.

Laura: Oh. So how many C's have you got?

Ron: Because you're missing two. You're missing. Wait, I've got four C's. Four times 12.

Laura: Yeah.

Ron: 011 and then eight H's. Nine H's.

Laura: Why have you got nine H's?

Ron: Because there's an H attached to one of the oxygens.

Laura: Yeah?

Ron: Yeah.

Laura: Should there be an H on top of the fourth C?

Ron: No, one of the C's. Wait, hang on.

Laura: One of the C's has only got three bonds, hasn't it?

Ron: Well, it's got two bonds to an oxygen.

Laura: Yeah, And One bond to another oxygen.

Ron: And then you have. I know. You are right.

Laura: We need to work out how much glycerol we need

Yeah. I tried to do it without, um, drawing it down. Yeah. Yes, you are correct. Okay. What was the number you got?

Laura: I got 88.104.

Ron: Cool. Okay. Well done. Um, right. Okay. What do you think the next step will be? I'll help, but just let's get there together.

Laura: So what are we trying to do?

Ron: We're trying to work out how much glycerol we need to react with, uh, all these fatty acids that we've got.

Laura: Do we have to make them the same number? I don't know. Get them to the same amount. So 88.104 grammes would be one mole of fatty acid. And, uh, 92.094 grammes would be one mole of glycerol. So how many moles is equal?

Ron: Almost. But is it a one to one relationship between the fatty acids and the glycerol?

Laura: No, but that's what we'd have to work out, isn't it? Multiply them until you get a.

Ron: Uh. But I mean in terms of the equation, like the reaction that's happening?

Laura: Oh, no idea.

Ron: Well, you said this earlier.

Laura: Oh, three fatty acids.

Ron: Yeah, yeah, yeah.

Laura: So do we have two times 88.104 by three?

Ron: Yep, that's part of it.

Laura: Ooh, more maths. 88 times three. 264.312.

Ron: Okay then, so

01:10:00

Ron: that's. So, uh, that's essentially. Yeah, the weight of the reactants on that side. So now that we've got it in that molecular weight, we've got a one to one between the glycerol and the fatty acids.

Laura: Okay.

Ron: So we've got 150 grammes of those fatty acids, don't we?

Laura: Yeah.

Ron: So we need to work out how many moles of our, ah, reactants we've got. So how do we do that?

Laura: I don't know.

Ron: There's only so many different things you can do with numbers.

Laura: Fire them out, multiply. No, divide.

Ron: Yes.

Laura: So divide by 150.

Ron: Why would it. Think it through. But don't just say stuff.

Laura: Hey.

Ron: Right, okay, let's. Okay, think about it like this, right? You got 150 grammes of it.

Laura: Yeah.

Ron: If you were dividing by the 150, the heavier the thing got, the more moles would be in the 150grammes, because that would make that some bigger. Does that make sense?

Laura: Yeah.

Ron: Think about it before you just say things, Laura. Uh, so if you've got something that weighs 150 moles, uh, like the molecular mass of 150. And you divided that by 150, you'd have one mole of it. If it weighed 300 and you divided it by 150, that by your calculation there, you'd have two moles of it. Does that make any sense?

Laura: No.

Ron: Surely you must see why.

Laura: You'd think, wouldn't you? You would think.

Ron: You must see that if it's heavier, uh, there would be less of it in a defined weight. You must know that. I think dogs know that.

Laura: So divide my number, um, by 150.

Ron: That's what we were already talking about. That's what you said the first time.

Laura: So divide 150 by my number.

Ron: Yeah. Because then if the weight of the thing gets bigger, the number of moles you can fit into the defined weight will get smaller. That makes sense.

Laura: Everyone else understands 0.568 to three decimal places.

Ron: Sure. Okay, so that's how many moles of our reactants there are. So now we need to find out how many grammes of glycerol we need.

Laura: 52 grammes to the same decimal places.

Ron: As everything else, please.

Laura: 0.309.

Ron: Close enough to be a rounding error.

Laura: How. What did I round wrong?

Ron: Um, I don't know. It's my. I got 52 point, uh, two six four, but it's close enough to just be a rounding error.

Oh, okay. One more. How much water in grammes can I expect to produce in this reaction

Laura: Oh, okay. That was a slog, wasn't it?

Ron: That was really hard work. Yeah.

Laura: Is that over now?

Ron: No. One more. How much water in grammes can I expect to produce in this reaction?

Laura: Water? Where the. Has water come from?

I turned off notifications for Discord because I was doing something

Laura: There we go. They've had an episode now, haven't they?

Ron: Maybe.

Laura: When am I gonna edit that?

Ron: Get. Get Meg to do it. She needs to stop fucking pulling her.

Laura: I feel very out of touch with the podcast since I had to turn off notifications for Discord. I don't know what's going on anymore.

Ron: Shall I check?

Laura: I need to turn that back on, I think.

Ron: Why did you turn it off?

Laura: Um, because I was doing something, and I was trying my best to have an attention span.

Ron: What's happening? Uh, Jasper caught up on the Agathon, right? But, uh, his laptop on a cat tower, and that provided some laughs for the listeners. Uh,

01:15:00

Ron: um, they discussed us as James Bond, like Lex education, doing a sort of Muppets takeover. Bond. Quite a lot. Um, they said, obviously, you were Bond. They. They put me As Q Bond, mystic came in saying Laura's an inventor, though.

Laura: Yeah, that's true Mystic. You've always got my back.

Ron: Yeah, uh, there was chat about that. Um, the usual discussion of, um, of alternative titles I haven't posted so long.

Laura: I'm so sorry, guys.

Ron: Carol chimed in to say that I'd gotten, um, a lot of the scoring on the exams.

Laura: Oh, no. Did I do better or worse?

Ron: I think it evened out or. You did slightly better, yes. Um, but, um, probably a genius. Yeah. I don't know who did this. I don't know if. Because Carol's posted a screenshot, but whoever did do that, you can fuck off. Um, did what? Went through and checked my mark.

Laura: Carol did. I think that. I think that came through before I did the old mutathon.

Ron: Oh, I see. Um, what else? Oh, there's a new channel called Good news.

Laura: Good News. Wakey wakey.

Ron: In the Wheel of Laura column there. Uh.

There's a poll for what our Bond film would be called

All right, we will put a vote in on this. There's a poll for, um, what our Bond film would be called. Um, Octo Gnocchi, Quantum Bins of Solace, Thunderbollock Moon. Uh, uh, don't get that one. For your eggs only.

Laura: Muna, you've never watched ghosts, have you?

Ron: No.

Laura: So Muna, uh, is what the. The caveman calls the moon.

Ron: Oh, right. For your eggs only. Um, which I'm going to vote for. I think that's the best one. And Casino Ronald.

Laura: That's cute.

Ron: Yeah. But we're voting for your. Oh, for your eggs only is, uh, streaming into the league.

Laura: We are a pretty eggy podcast.

Ron: Yeah.

Laura: Oh, uh, the other day, Ron, I had two egg sandwiches in one day.

Ron: Bloody hell.

Laura: And do you know what was crazy is when I edited the egg a thon, I was eating an egg mayo sandwich while I edited it.

Ron: Egg mayo was the most palatable of all of the egg A thons so far.

Laura: Did we announce what we're gonna do for next year's Eggathon?

Ron: Do we know?

Laura: Yeah. Vegan egg products. Oh, yeah, we're gonna have a vegan egg. I predict it's going to be dry.

Ron: Let's do vegan eggs. And then maybe the year after or as part of next year, um, we could do, like, different. Like, quails and ducks, ostriches, all of the birds in the aviary.

Laura: One of the starlings that, um, that nests in my garage roof. Um, their babies have just hatched, and they pushed out a little bit of the eggshell that they didn't need anymore. And it's a really lovely pale blue. Oh, maybe next year I could steal one of their eggs and we could eat it. Let's become goannas.

Ron: Oh, it just makes me think of Charlie and Frank fight with, like, the strength of a crow.

Laura: Do you reckon you can buy crow's eggs? We should do some research into what eggs you're allowed to eat. Can you eat any birds? Eggs?

Ron: Crows. Eggs for sale. Uh, where can I buy crows? On Reddit R crows.

Laura: Uh, I think you're about to get. You're about to get enrolled in a cult.

Ron: Where do you live? The U.S. canada, Mexico, Russia and Japan. It's illegal to own crows and other birds.

Laura: Well, thank God we live in Freedomland, where you can own as many crows as you like.

Ron: One of the reasons it's illegal to own a crow, Raven, is because they're very trainable birds. They will attack on command and can be taught to take money or other valuables they're too powerful to.

Laura: But what about their eggs? Not interested. M in an adult crow.

Ron: Anyway, um, see you next week, everybody.

Laura: Don't have milk, do they? No. Okay, bye, everyone.

Ron: Class dismissed.
