Being a chemist myself, I would like to contribute: The more colours you see, the more likely that it is fake. Most chemicals are colourless or white, coloured chemicals are in the minority and when you find them in household chemicals it is most likely dyed.
@@Thaumius ...It was just a dumb joke I heard in my inorganic chemistry class, because it seemed like you were more likely to find colorful inorganic compounds (eg. cobalt, copper sulfate, etc. - and tests like the infamous 'flame test'). And half the experiments we ran in our organic chemistry lab stunk. lol
@@Rime_in_Retrograde it's not that far off. Most organic compounds are going to be clear (for liquids), white (for solids), or yellow (for both). There are some colored compounds, but they're not nearly as common as in inorganic, where you've got d orbital splittings of transition metals that can make some really neat colors.

In the Mr. Bean chemistry scene, I think someone KNEW it was a backwards set-up, mainly as a chemist’s inside joke. I can definitely imagine that happening on set.
@@Zeguyfromgermany Yeah, I think someone needed to explain Mr Bean to her. He does everything the wrong way, and generally causes mayhem and destruction, that is the point of the character. If his chemistry setup was wrong and he was using poor safety practice then that was absolutely what they were going for. Faulting it is like criticising Airplane by saying the automatic pilot wouldn't actually be an inflatable doll in real life.
If I'd had her as one of my teachers, I almost certainly would have pursued chemistry. My favorite part was at around time 13:00. She must be an absolutely wonderful teacher.
If it depends on the other person whether you pursue a certain subject or not, it simply means you are not truly passionate about it. My high school chemistry teacher was a dismal, not much better on my studies either. Nevertheless, once I discovered this subject and how wondrous it is, I swore I would never abandon it and my passion for chemistry is still very much alive.
Im not a chemistry major, but she was my professor at UT for general chemistry during the peak of Covid. She was a great teacher, though the course was hard, still one of my favorite courses at UT.
GOD, the absolute JOY she exhibits with her experiments is just top tier, I absolutely loved this! I would love to see Biberdorf come back for more, she really got my hyped about chemistry!
As a chemistry graduate, I can say these experiments she performed are so fun, especially the nylon one, it's so cool to see it come out of "nowhere" also as soon as I heard split the water in the Chernobyl scene I actually gasped, that's a crazy amount of energy.

@@Nooneiscomingforme Disclaimer: Not a chemist I can read 1,6 Hexaned(ioic acid - probably) for the first part and something ending in "sebacoyl chloride" for the second part The first part is - for sure - a "monomer", I think the chloride might essentially be like a developer but maybe it's a different monomer This is an example of a polymerisation reaction, the end part of the monomer is broken off or changed by the second reactant and "stuck on" to more of itself or another monomer to create a much longer molecule (poly-mer, made of many monomer parts) Someone else could it explain better, but there are multiple different options for chemicals that make nylons and I'm not entirely clear on which these are or how *exactly* they're reacting

The problem is we don't have good educational capacitation. Many love their professions, and even excel at them, but people usally believe that's enough to be a good teacher. It isn't, being a teacher is a profession in itself, you need to learn it, it takes years since it's literally another career or at least an specialization, and very few have any interest in learning how to teach, they just think is about repeating what you know to others, that's why it gets dull and boring for everyone. Schools should offer and demand at least an specialization in education to become a teacher.
Second degree burns are the most painful. Third degree burns cause nerve damage, and when the nerves are dead or, in this case, burnt away, you will stop being able to feel pain. Instead of pain, you will feel a numbness where the 3rd degree burn is. There will be some pain around the 3rd degree burns, because the other nerves nearby would still be sending signals to the brain. But that is nowhere near the pain of a second degree burn. I've had a second degree burn on my back, quite a large one. It was the most painful thing I ever experienced. The doctor said I'm lucky I didn't get 3rd degree burns in the area, because while that would not be as painful, I would lose sensation because of the dead nerves. Damaged nerves and completely dead nerves can cause issues with mobility. For example, if you get nerve damage in your hand, you may have trouble opening and closing it, or moving the fingers, or the wrist. Nerve damage can result in phantom pain, and it can be chronic. Phantom pain is just as real as when nerves are sending signals to your brain, so it's not "fake" pain. Nerve damage can be quite devastating to a person's quality of life. So, while I may have been in a tremendous amount of pain when I got the 2nd degree burn, it's possible I could've gotten chronic phantom pain if I got a 3rd degree burn that burnt away the nerves.
When I was a young man, somewhere around 11 or 12, I got a really bad burn on my right hand. My uncle was torch welding the railing to my grandma's porch, the kind of railing that has the little grooves on top for grip or something. He finished and walked away, shortly after I come along and grab the rail without thinking. My hand cooked to the surface of that metal like he literally had to rip it off and flesh was left behind. Hospital said it was a bad second but not quite third degree. Took forever to heal and to this day more than 20 years later I have the ridges in my palm and almost no feeling in the area.
The Big Bang Theory hired proper scientists for most of the science scenes so it isn't a surprise that they got those scenes write. Now if only they hired proper comedians to write the jokes it would be watchable.
It’s so cool how she gets so excited over the simplest chemistry (experiments), probably being a long-time professor already. Good to see she still kept all her enthusiasm for what she does. There aren’t many who could say the same about their profession.
I can not get over the fact that you theoretically could actually make Web Fluid. The Nylon example she showed was so cool. I wonder what other chemicals it would take to have IRL web fluid that functions as it does in the movies (where it could support the weight of a high schooler swinging around at high velocity)... Like is it theoretically possible to make fully functioning web fluid and we just haven't because there's no practical non-Spider Man related need for it?
Our current issues with spider silk fabrication is that we are unable to reliably recreate the exact molecular structure of spider silk. Even with genetic modification of silk worms the silk they end up producing is no where near as strong as the real thing. Alpha Fold is an AI that can predict the folding of protein with i believe it's 90% accuracy(it's only going to get better). Keep in mind with chemistry is that structure determines function. Alpha Fold gives us the potential to fully reverse engineer an organism that can make the necessary proteins that can eventually produce spider silk that is 90% close to the real thing. This is still a ways off, but large scale production of synthetic spider silk could be a thing in the next ~20 years. The functions of this would be insane, first of all kevlar ie bullet proof vests, and honestly could be bullet proof normal cloths like John Wick. Anything that is currently made with nylon would be replaced with it. I'm sure an Engineer could come up with other applications other Spider-Man, and what I've listed. Edit: i looked up Alpha folds accuracy. Also it turns out that Alphafold was used to help better understand SARS-CoV-2. There is a deep mind article all about it.
Well, as far as using nylon specifically as a web fluid (and not synthetic spider silk, or something else, as mentioned in the other comments), it theoretically could be strong enough as a material to hold a person’s weight (it’s what parachute cord is made of, for example). However, paracord is as strong as it is because it is a woven rope containing an outer sheath and multiple inner cords, all woven out of many individual nylon filaments. So one single filament (as you would get if you shot out a single stream of liquid nylon) would not be anywhere Near strong enough to hold a human up. The second problem with using this method to make a working web fluid is that nylon isn’t sticky. So you’d need another chemical compound on the end of the strand, strong enough to anchor the web to something, or you’d have to come up with some other way for the nylon strand to somehow tie itself onto something, so it was secure. Some other problems that come up: - The nylon actually only forms at the interface of the two chemicals used in the reaction, so you’d have to create some sort of special mixing device that would keep the liquids separate, but allow them to mix together perfectly to make the nylon filament. - You would need to come up with some sort of means of propelling the nylon out of the mixing device, so it would shoot out at a distance like in the movies/comics. You’ll notice that she has to physically pull the strand out here, to form the filament. - The chemicals used in this reaction are fairly toxic, so you wouldn’t actually want to touch the rope with your hands. Typically the nylon needs to be rinsed, before you can handle it with your bare hands. - The volume of chemicals needed to make the webs as you see Spider-Man use in the movies would be Way larger than the teeny little vials of fluid that he is shown using. - Let’s play with this as a hypothetical though! Say you can overcome all of the above problems - perhaps by creating a device that perfectly mixes the two web fluid chemicals to create multiple nylon strands, which it then weaves together into a secure rope, rinsing the toxic chemicals away in the process. It could then apply an extremely strong, fast curing adhesive to the end of the web before it is shot out, and use some sort of mechanism, perhaps with compressed air, to propel the web rope out of the shooter. Let’s say you create a large backpack that holds all the chemicals for the nylon, adhesive for sticking, water for rinsing, compressed air for shooting, and a power source for operating everything, and attach it via wires/hoses to your wrist mounted device that handles the actual making and shooting of the rope/web. IF you could figure out the myriad technical, mechanical, and chemical problems that would come up in the creation and testing of that apparatus, then yes, theoretically you could create a nylon-based web fluid, using the chemical process shown here, and successfully recreate the web slinging (somewhat) as shown in the movies! :) Realistically however, for any actual Spider-Man related (or Spider-Man similar) uses, it’s much simpler to just have a pre-made, strength tested rope, stored in some sort of spool, with a hook or other attachment device attached to the end, and a device that projects the rope and hook out to your intended attachment point - hence the grappling gun ;)
I prepped chemistry during college, and we don't actually get to do the showy experiments very often. Lots of putting solids in liquids, titrating, waiting 30 minutes for a hotplate to get to EXACTLY the right temp so we don't burn off our desired reagent, and....lots and lots and lots of notes/math. It's mentally invigorating and can be very rewarding, but doing something like elephant toothpaste would make nearly any chemist jump for joy. I especially enjoy using methane bubbles to set myself on fire. Kids love to see it!!
As a safety pro, who tests respirators, in the breaking bad section, having those hoods under the respirator (not gas masks) make them useless because it's not sealing properly. Same reason why beards are a no no. Should be the other way around
What's the difference between a respirator and a gas mask? I suppose a gas mask is more specific towards a air purifying respirators as oppose to respirator which can mean either an APR or an ASR or even an SCBA.
@@shankhan547 respirators channels air through a canned filter and then you breath it in the other side. A gas mask you carry the air in a pressurized tank.
Beards are a no no unless you tuck it in and make a seal around the base of your skull. I wear gas masks when painting and it seals just fine with my beard. Just gotta tie it up and tuck it into itself that way I can seal the mask around my neck.
@@makatron This is not correct. A gas mask is a respirator. Gas masks have filters/cartridges too, they are typically considered as an air purifying respirator. That's what the filters do, they filter and purify the air you breathe into the mask. Bringing your own tank of air can be classified as atmosphere-supplied respirators or self contained breathing apparatus.
i could sit and listen to her talk about movie chemistry all day long! i"ve never liked chemistry in school but she's so invested and smart and charming and she still think's even the smallest experiment seems super fun!
She mentioned Aqua Regia. The character of Burt mentioned it in Return of the Living Dead (1985) to get rid of one of the reanimated bodies. Kate is hilarious. She full on geeked out when she made nylon. She definitely loves Chem
In italy we have acquaragia, a strong and very volatile organic solvant which, while it needs to be handled with care, is obviously nowhere as dangerous as that mix of acids. I hope that no one ever bought and used the worng one
i had the biggest crush in my life on my chemistry teacher, but besides being a gorgeous woman, the think i loved the most was how passionate she was about chemistry. this was a nice way to remember her
Same for a certain literature prof I know. Yeah, she was very pretty but what killed me was she was so passionate and such a deep yet accessible thinker. I was a goner.
Fun fact: Aqua Regia (her preferred acid) is actually used in methamphetamine manufacture to dissolve platinum to create chloroplatinic acid in the process of creating ammonium chloroplatinate, which is in turn used to create Platinum Dioxide, also known as Adam's Catalyst. This is the catalyst used in reductive amination of Phenylacetone (P2P) with methylamine to create Methamphetamine, and this is how they do it in the show.
Nylon: while string like it can easily break, horrible for holding structures without being processed, great for clothes,and finally, cant hold our friendly neighborhood spiderman while he uses it to swing on. Web Liquid: Is great at swinging on, holding large structures together, very sticky, and finally, isnt real.
It’s Dr.B!!!!! I had her for 2 of my intro to chem classes and she’s one of the only lecturers who can keep students awake at 8am with her enthusiasm 🤘🤘🤘
As someone studying chemistry this was a cool video. I do want to correct one thing: 3rd degree burns aren't all that painful... They damage so deep the nerves are just gone so you can't feel them
I loved that she did experiments to show the point she was making and not only talking about the clips. I would watch more of these for sure! Had no idea you could make nylon with some liquids, that was perfect for Spiderman. So cool!
I LOVE how excited she gets with the experiments!! Gosh I enjoyed this one so much! The best one so far! Lovely host and great explanations for the chemistry that we saw. I hope to see her again in second part :)
That isn't how the Xenon poisoning works (did a great job on the non nuclear-stuff, though). The Xe isotopes are constantly produced by the reactor and then either absorb a neutron and decays quickly or they decay away in a few hours or days. This always exists in reactor at equilibrium. When you shut down the reactor, the Xe keeps growing in for a while, as other elements are still decaying to it and the reactor isn't removing it's portion. So, the Xe will build up for a while before decaying away and when this happens there is too much excess negative reactivity in the system and the reactor can't sustain a chain reaction.
@@st0rmbreaK "weak" literally just refers to the dissociation constant (pKa), it literally has nothing to do with corrosiveness. HF is widely known to be EXTREMELY corrosive to almost everything including **glass** and will do much much more damage to human flesh than sulfuric or hydrochloric "strong acids" Antimony pentafluoride, one of the strongest "superacids" is highly dangerous. Why? The main hazard is "Releases hydrofluoric acid upon contact with water or biological tissues"
Yeah, she talked about xenon being "burned" like literally, because of high temperatures. The "burning" of xenon is figurative, by being bombarded by neutrons. What causes xenon buildup is the lower flux of neutrons when the reactor is at lower power. To be fair, that's physics, not chemistry.
When i first took her class for chemistry in college, i never thought i would see her on here lol. Her enthusiasm in the subject did help me enjoy the class more tho
Am in chem undergrad and always feel like I don't know anything. The fact that I knew everything that she said was nice. Also, I really liked the enthusiasm. Never had a teacher with this much enthusiasm, but I would probably thing it is cringe back at highschool. Now, it's awesome to see enthusiasm
You're mostly right about the Xenon! What's important to mention though is that the 'burning off' of Xe-135 isn't a chemical process, but a nuclear one. Xe-135 is part of U-235's decay chain, so it naturally tends to build up a bit as the reaction goes on. It's also very, very good at absorbing neutrons, and fewer neutrons flying around equals a slower reaction. Iirc, it has a half-life of about 9 hours, so after a shutdown, you need to wait a couple hours for it to decay away into less troublesome isotopes. The workers at Chernobyl were under a lot of pressure to perform a specific test, and they ended up trying to 'overpower' the Xenon.
I came to the comments looking for this correction, thanks for writing it before me! Small clarification: Xe-135 is in the decay chain of some of U-235's fission products, not the decay of U-235 itself.
The reactors in Chernobyl were badly designed to begin with. No sane engineer or designer would design a positive void coefficient reactor where everything is launched into a positive feedback loop once the phase of the non-heavy water changes to superheated vapour. The Xenon burn-off (and also the stupid withdrawal and simultaneous slamming of the control rods) was the straw that broke the reactor's back
I didn’t do incredibly well in chem in undergrad, but I loved lab so much. I once synthesized aspirin in organic chemistry lab. So awesome. One of my dreams is to have my own lab to do my own experiments.
Organic chemistry was my favorite science class. Every equation had ONE answer... and I loved it, the processes were so clean. And if you couldn't get the basics, well, then you hated organic chemistry.
@@dianeridley9804 That’s only true if you completely ignore stereochemistry and the fact that a molecule can have multiple active centers of reactivity. Mechanisms can only be supported, not proved. it’s not uncommon for a reaction to take multiple paths creating multiple products.
@@dianeridley9804 As a specific example, electrophilic aromatic substitution on a mono substituted benzene will yield two major products if the substituent is an ortho-para director.
@@dianeridley9804 Most reactions in organic chemistry definitely have more than one answer. Probably only in paper, you can see what the major product would be. Even something as simple as nucleophilic substitution reaction, for example, you can have side products of elimination.
I love that she says "you'll need concentrated hydrogen peroxide" like the average person can get 35% H2O2. Edit: I just confirmed that both the EU and US implemented restrictions on the sale of H2O2 above 12% concentration. The changes are recent (last few years).
The average person can get 35% H2O2. or at least, we've had it in my house before, and we'd no special reason to have access to special chemicals. Pretty sure we got it at a health food store.
35% isn't so bad, but when you start going north of that it quickly gets out of hand. Like creating sustained fire on contact by using your flesh as the 'fuel' portion of the fire triangle out of hand.
Availability depends on your jurisdiction. Rules were recently changed in the EU and US which can make it more difficult to get 35%. And yes, everything I've seen says that above 35% is dangerous and you don't want it in your house.
I almost failed chemistry, I tried so hard in that class and still barely passed the school year. This lady tho, she made learning about chemistry engaging and fun.
The science in The Martian book was completely solid but they skipped parts for the sake of translating the several hundred pages story to a motion picture, Andy Weir explained the whole hydrazine to water reaction a lot better in the book. Chemistry is the only class that I gave it my 100% and barely understood a thing, straight As for everything but chemistry.
The point here is that he simply doesn't have the protective equipment to survive the explosion. If Andy Weir wrote something like that then it's also garbage chemistry. Weir is hack anyway, I've read his latest novel don't even remember the name, but that was full of absolutely batshit "science" that reads like a high schooler wrote on acid.

The more colours you see, the more likely that it is fake. Most chemicals are colourless or white, coloured chemicals are in the minority and when you find them in household chemicals it is most likely dyed.
Isn't there a joke that goes something like - if you want chemistry that smells do organic chemistry, but if you want color do inorganic chemistry?
@@Thaumius ...It was just a dumb joke I heard in my inorganic chemistry class, because it seemed like you were more likely to find colorful inorganic compounds (eg. cobalt, copper sulfate, etc. - and tests like the infamous 'flame test'). And half the experiments we ran in our organic chemistry lab stunk. lol
@@Rime_in_Retrograde it's not that far off. Most organic compounds are going to be clear (for liquids), white (for solids), or yellow (for both). There are some colored compounds, but they're not nearly as common as in inorganic, where you've got d orbital splittings of transition metals that can make some really neat colors.
I'd also add yellow to the list of colours.
In organic chemistry, it's all going to be gross smelling yellow liquid.
Bring her back she’s hella cool with the chemist things she explains.
The fact she ripped through everything was awesome too..This one had way more scenes than usual I feel like but answered everything effortlessly
Can she have her own TV show or something? Her knowledge and enthusiasm is refreshing.
She's attractive too... let's be real, high school students would pay WAY more attention with her teaching for that ALONE.

In the Mr. Bean chemistry scene, I think someone KNEW it was a backwards set-up, mainly as a chemist’s inside joke. I can definitely imagine that happening on set.
And Mr. Bean being Mr. Bean, handling chemicals in a sensitive way would be total out of character, too!
@@Zeguyfromgermany Yeah, I think someone needed to explain Mr Bean to her. He does everything the wrong way, and generally causes mayhem and destruction, that is the point of the character. If his chemistry setup was wrong and he was using poor safety practice then that was absolutely what they were going for. Faulting it is like criticising Airplane by saying the automatic pilot wouldn't actually be an inflatable doll in real life.
I can imagine the Mr. Bean team to do it in a way that irks only the chemists but not the usual audience :D
@@mattc3581they’re talking about the realism of it. It’s not realistic. That’s all that the video was about.

If I'd had her as one of my teachers, I almost certainly would have pursued chemistry. My favorite part was at around time 13:00. She must be an absolutely wonderful teacher.
I loved it that she was so purely gleeful about the foam, like a little kid would be
If it depends on the other person whether you pursue a certain subject or not, it simply means you are not truly passionate about it. My high school chemistry teacher was a dismal, not much better on my studies either. Nevertheless, once I discovered this subject and how wondrous it is, I swore I would never abandon it and my passion for chemistry is still very much alive.
@@sergethegrim I was passionate about a number of subjects, including chemistry.
Im not a chemistry major, but she was my professor at UT for general chemistry during the peak of Covid. She was a great teacher, though the course was hard, still one of my favorite courses at UT.
Maybe a good teacher but I get the impression she's a perfectionist, and that may make her a hard grader. So, I'd def pass
GOD, the absolute JOY she exhibits with her experiments is just top tier, I absolutely loved this! I would love to see Biberdorf come back for more, she really got my hyped about chemistry!
As a chemistry graduate, I can say these experiments she performed are so fun, especially the nylon one, it's so cool to see it come out of "nowhere" also as soon as I heard split the water in the Chernobyl scene I actually gasped, that's a crazy amount of energy.
Crazy that it gets hot enough to split the water then ignite it, then split it again etc. Infinite energy source.
@PonzooonTheGreat It only got that hot because it was in the middle of a catastrophic failure. We don't have the capability to harness that kind of power. It's a LOT to split water.
What chemicals were used to make the nylon?
@@Nooneiscomingforme Disclaimer: Not a chemist
I can read 1,6 Hexaned(ioic acid - probably) for the first part and something ending in "sebacoyl chloride" for the second part
The first part is - for sure - a "monomer", I think the chloride might essentially be like a developer but maybe it's a different monomer
This is an example of a polymerisation reaction, the end part of the monomer is broken off or changed by the second reactant and "stuck on" to more of itself or another monomer to create a much longer molecule (poly-mer, made of many monomer parts)
Someone else could it explain better, but there are multiple different options for chemicals that make nylons and I'm not entirely clear on which these are or how *exactly* they're reacting
@@Nooneiscomingforme 1,6-diaminohexane first, then a solution of decanodioyl in cyclohexane floated on top. Yes I just looked that up, I have done this experiment before but couldn't remember the reagents :P
If we had chemistry teachers like here we'd definitely learn more she loves this stuff and it definitely rubs off on you
The problem is we don't have good educational capacitation. Many love their professions, and even excel at them, but people usally believe that's enough to be a good teacher. It isn't, being a teacher is a profession in itself, you need to learn it, it takes years since it's literally another career or at least an specialization, and very few have any interest in learning how to teach, they just think is about repeating what you know to others, that's why it gets dull and boring for everyone. Schools should offer and demand at least an specialization in education to become a teacher.
1. There are plenty of teachers like that out there.
2. There would be more if teachers were paid according to their value to society.

Second degree burns are the most painful. Third degree burns cause nerve damage, and when the nerves are dead or, in this case, burnt away, you will stop being able to feel pain. Instead of pain, you will feel a numbness where the 3rd degree burn is. There will be some pain around the 3rd degree burns, because the other nerves nearby would still be sending signals to the brain. But that is nowhere near the pain of a second degree burn. I've had a second degree burn on my back, quite a large one. It was the most painful thing I ever experienced. The doctor said I'm lucky I didn't get 3rd degree burns in the area, because while that would not be as painful, I would lose sensation because of the dead nerves. Damaged nerves and completely dead nerves can cause issues with mobility. For example, if you get nerve damage in your hand, you may have trouble opening and closing it, or moving the fingers, or the wrist. Nerve damage can result in phantom pain, and it can be chronic. Phantom pain is just as real as when nerves are sending signals to your brain, so it's not "fake" pain. Nerve damage can be quite devastating to a person's quality of life. So, while I may have been in a tremendous amount of pain when I got the 2nd degree burn, it's possible I could've gotten chronic phantom pain if I got a 3rd degree burn that burnt away the nerves.
That's why steam burns are the worse. steam doesn't kill the nerves like fire does.
When I was a young man, somewhere around 11 or 12, I got a really bad burn on my right hand. My uncle was torch welding the railing to my grandma's porch, the kind of railing that has the little grooves on top for grip or something. He finished and walked away, shortly after I come along and grab the rail without thinking. My hand cooked to the surface of that metal like he literally had to rip it off and flesh was left behind. Hospital said it was a bad second but not quite third degree. Took forever to heal and to this day more than 20 years later I have the ridges in my palm and almost no feeling in the area.
Legit freaking LOVE how passionate she is about chemistry, please make a part 2 with her and her awesome chemistry demonstrations!
The Big Bang Theory hired proper scientists for most of the science scenes so it isn't a surprise that they got those scenes write. Now if only they hired proper comedians to write the jokes it would be watchable.

For an ordinary guy who doesn't know much bout chemistry, this is a very insightful n thoughtful explanation for me to understand! Good job!
dont be a patetic Incel and read a chemistry book you faggyyy
It’s so cool how she gets so excited over the simplest chemistry (experiments), probably being a long-time professor already. Good to see she still kept all her enthusiasm for what she does. There aren’t many who could say the same about their profession.
Absolutely love her reaction to the experiments. Shows that she truly love what she does.
I can not get over the fact that you theoretically could actually make Web Fluid. The Nylon example she showed was so cool. I wonder what other chemicals it would take to have IRL web fluid that functions as it does in the movies (where it could support the weight of a high schooler swinging around at high velocity)... Like is it theoretically possible to make fully functioning web fluid and we just haven't because there's no practical non-Spider Man related need for it?
Our current issues with spider silk fabrication is that we are unable to reliably recreate the exact molecular structure of spider silk. Even with genetic modification of silk worms the silk they end up producing is no where near as strong as the real thing.
Alpha Fold is an AI that can predict the folding of protein with i believe it's 90% accuracy(it's only going to get better). Keep in mind with chemistry is that structure determines function. Alpha Fold gives us the potential to fully reverse engineer an organism that can make the necessary proteins that can eventually produce spider silk that is 90% close to the real thing.
This is still a ways off, but large scale production of synthetic spider silk
could be a thing in the next
~20 years. The functions of this would be insane, first of all kevlar ie bullet proof vests, and honestly could be bullet proof normal cloths like John Wick. Anything that is currently made with nylon would be replaced with it. I'm sure an Engineer could come up with other applications other Spider-Man, and what I've listed.
Edit: i looked up Alpha folds accuracy. Also it turns out that Alphafold was used to help better understand SARS-CoV-2. There is a deep mind article all about it.
it’s called rope
Well, as far as using nylon specifically as a web fluid (and not synthetic spider silk, or something else, as mentioned in the other comments), it theoretically could be strong enough as a material to hold a person’s weight (it’s what parachute cord is made of, for example). However, paracord is as strong as it is because it is a woven rope containing an outer sheath and multiple inner cords, all woven out of many individual nylon filaments. So one single filament (as you would get if you shot out a single stream of liquid nylon) would not be anywhere Near strong enough to hold a human up.
The second problem with using this method to make a working web fluid is that nylon isn’t sticky. So you’d need another chemical compound on the end of the strand, strong enough to anchor the web to something, or you’d have to come up with some other way for the nylon strand to somehow tie itself onto something, so it was secure.
Some other problems that come up:
- The nylon actually only forms at the interface of the two chemicals used in the reaction, so you’d have to create some sort of special mixing device that would keep the liquids separate, but allow them to mix together perfectly to make the nylon filament.
- You would need to come up with some sort of means of propelling the nylon out of the mixing device, so it would shoot out at a distance like in the movies/comics. You’ll notice that she has to physically pull the strand out here, to form the filament.
- The chemicals used in this reaction are fairly toxic, so you wouldn’t actually want to touch the rope with your hands. Typically the nylon needs to be rinsed, before you can handle it with your bare hands.
- The volume of chemicals needed to make the webs as you see Spider-Man use in the movies would be Way larger than the teeny little vials of fluid that he is shown using.
-
Let’s play with this as a hypothetical though!
Say you can overcome all of the above problems - perhaps by creating a device that perfectly mixes the two web fluid chemicals to create multiple nylon strands, which it then weaves together into a secure rope, rinsing the toxic chemicals away in the process. It could then apply an extremely strong, fast curing adhesive to the end of the web before it is shot out, and use some sort of mechanism, perhaps with compressed air, to propel the web rope out of the shooter. Let’s say you create a large backpack that holds all the chemicals for the nylon, adhesive for sticking, water for rinsing, compressed air for shooting, and a power source for operating everything, and attach it via wires/hoses to your wrist mounted device that handles the actual making and shooting of the rope/web. IF you could figure out the myriad technical, mechanical, and chemical problems that would come up in the creation and testing of that apparatus, then yes, theoretically you could create a nylon-based web fluid, using the chemical process shown here, and successfully recreate the web slinging (somewhat) as shown in the movies! :)
Realistically however, for any actual Spider-Man related (or Spider-Man similar) uses, it’s much simpler to just have a pre-made, strength tested rope, stored in some sort of spool, with a hook or other attachment device attached to the end, and a device that projects the rope and hook out to your intended attachment point - hence the grappling gun ;)

The fact that she works with this all the time yet is still always fun excited about it shows she’s in the right profession
I prepped chemistry during college, and we don't actually get to do the showy experiments very often. Lots of putting solids in liquids, titrating, waiting 30 minutes for a hotplate to get to EXACTLY the right temp so we don't burn off our desired reagent, and....lots and lots and lots of notes/math.

As a safety pro, who tests respirators, in the breaking bad section, having those hoods under the respirator (not gas masks) make them useless because it's not sealing properly. Same reason why beards are a no no. Should be the other way around
What's the difference between a respirator and a gas mask? I suppose a gas mask is more specific towards a air purifying respirators as oppose to respirator which can mean either an APR or an ASR or even an SCBA.
@@shankhan547 respirators channels air through a canned filter and then you breath it in the other side. A gas mask you carry the air in a pressurized tank.
Beards are a no no unless you tuck it in and make a seal around the base of your skull. I wear gas masks when painting and it seals just fine with my beard. Just gotta tie it up and tuck it into itself that way I can seal the mask around my neck.
@@deathninja16 yeah I find a way to seal it with my beard just fine too
@@makatron This is not correct. A gas mask is a respirator.
Gas masks have filters/cartridges too, they are typically considered as an air purifying respirator. That's what the filters do, they filter and purify the air you breathe into the mask.
Bringing your own tank of air can be classified as atmosphere-supplied respirators or self contained breathing apparatus.
i could sit and listen to her talk about movie chemistry all day long! i"ve never liked chemistry in school but she's so invested and smart and charming and she still think's even the smallest experiment seems super fun!

Bro we share the same fate
Same for a certain literature prof I know. Yeah, she was very pretty but what killed me was she was so passionate and such a deep yet accessible thinker. I was a goner.
Fun fact: Aqua Regia (her preferred acid) is actually used in methamphetamine manufacture to dissolve platinum to create chloroplatinic acid in the process of creating ammonium chloroplatinate, which is in turn used to create Platinum Dioxide, also known as Adam's Catalyst. This is the catalyst used in reductive amination of Phenylacetone (P2P) with methylamine to create Methamphetamine, and this is how they do it in the show.

That isn't how the Xenon poisoning works (did a great job on the non nuclear-stuff, though). The Xe isotopes are constantly produced by the reactor and then either absorb a neutron and decays quickly or they decay away in a few hours or days. This always exists in reactor at equilibrium. When you shut down the reactor, the Xe keeps growing in for a while, as other elements are still decaying to it and the reactor isn't removing it's portion. So, the Xe will build up for a while before decaying away and when this happens there is too much excess negative reactivity in the system and the reactor can't sustain a chain reaction.
Also just completely lied about Hydrofluoric acid at the beginning
about what? HF *is* a weak acid
@@st0rmbreaK "weak" literally just refers to the dissociation constant (pKa), it literally has nothing to do with corrosiveness. HF is widely known to be EXTREMELY corrosive to almost everything including **glass** and will do much much more damage to human flesh than sulfuric or hydrochloric "strong acids"
Antimony pentafluoride, one of the strongest "superacids" is highly dangerous. Why? The main hazard is "Releases hydrofluoric acid upon contact with water or biological tissues"
@@WallBush It's highly corrosive but it's regarded as a weak acid. You might be mixing HF up with HCl (hydrochloric acid.)
Yeah, she talked about xenon being "burned" like literally, because of high temperatures. The "burning" of xenon is figurative, by being bombarded by neutrons. What causes xenon buildup is the lower flux of neutrons when the reactor is at lower power. To be fair, that's physics, not chemistry.
Her passion and enthusiasm in the elephant toothpaste reaction was awesome!!!
When i first took her class for chemistry in college, i never thought i would see her on here lol. Her enthusiasm in the subject did help me enjoy the class more tho
Her pure, unadulterated excitement with the recreations is outstanding!
Am in chem undergrad and always feel like I don't know anything. The fact that I knew everything that she said was nice. Also, I really liked the enthusiasm. Never had a teacher with this much enthusiasm, but I would probably thing it is cringe back at highschool. Now, it's awesome to see enthusiasm
13:05 reignited my love for chemistry, thank you
You're mostly right about the Xenon! What's important to mention though is that the 'burning off' of Xe-135 isn't a chemical process, but a nuclear one. Xe-135 is part of U-235's decay chain, so it naturally tends to build up a bit as the reaction goes on. It's also very, very good at absorbing neutrons, and fewer neutrons flying around equals a slower reaction. Iirc, it has a half-life of about 9 hours, so after a shutdown, you need to wait a couple hours for it to decay away into less troublesome isotopes. The workers at Chernobyl were under a lot of pressure to perform a specific test, and they ended up trying to 'overpower' the Xenon.
It's thoroughly possible that 135Xe is the single most potent neutron poison known.
I came to the comments looking for this correction, thanks for writing it before me! Small clarification: Xe-135 is in the decay chain of some of U-235's fission products, not the decay of U-235 itself.
The reactors in Chernobyl were badly designed to begin with. No sane engineer or designer would design a positive void coefficient reactor where everything is launched into a positive feedback loop once the phase of the non-heavy water changes to superheated vapour. The Xenon burn-off (and also the stupid withdrawal and simultaneous slamming of the control rods) was the straw that broke the reactor's back
@@yoloswag4lyfe xD same here, what a relief
Badly designed or not, there are several RBMK reactors still operating. Doesn't that yield a nice warm & fuzzy feeling deep down inside?

I didn’t do incredibly well in chem in undergrad, but I loved lab so much. I once synthesized aspirin in organic chemistry lab. So awesome. One of my dreams is to have my own lab to do my own experiments.
Organic chemistry was my favorite science class. Every equation had ONE answer... and I loved it, the processes were so clean. And if you couldn't get the basics, well, then you hated organic chemistry.
Aspirin synthesis is so fun, the mechanism is interesting too. Started with methyl salicylate which smells lovely :)
@@dianeridley9804 That’s only true if you completely ignore stereochemistry and the fact that a molecule can have multiple active centers of reactivity. Mechanisms can only be supported, not proved. it’s not uncommon for a reaction to take multiple paths creating multiple products.
@@dianeridley9804 As a specific example, electrophilic aromatic substitution on a mono substituted benzene will yield two major products if the substituent is an ortho-para director.
@@dianeridley9804 Most reactions in organic chemistry definitely have more than one answer. Probably only in paper, you can see what the major product would be. Even something as simple as nucleophilic substitution reaction, for example, you can have side products of elimination.

Now give me the 5 levels explained with the chemist
Love how the chemistry stuff happens and Kate basically turns into a golden retriever
God, I love how excited she is by chemistry. Like, in all the bits where she's doing simple chemistry experiments, she's just bubbling with joy
I love that she says "you'll need concentrated hydrogen peroxide" like the average person can get 35% H2O2.
Edit: I just confirmed that both the EU and US implemented restrictions on the sale of H2O2 above 12% concentration. The changes are recent (last few years).
The average person can get 35% H2O2. or at least, we've had it in my house before, and we'd no special reason to have access to special chemicals. Pretty sure we got it at a health food store.
35% isn't so bad, but when you start going north of that it quickly gets out of hand. Like creating sustained fire on contact by using your flesh as the 'fuel' portion of the fire triangle out of hand.
Availability depends on your jurisdiction. Rules were recently changed in the EU and US which can make it more difficult to get 35%.
And yes, everything I've seen says that above 35% is dangerous and you don't want it in your house.
Just put it on a warm hotplate...
You can still do it, it's just not as effective of a reaction. Some people add water to make it less messy.

@@rooost9856 it's not exactly common either
Whenever I hear representation I cringe up into a ball. "Representation" is affirmative actions cousin. Not good for anyone. Absolutely insane that this is going on in the medical field.
@@HonkeyKong54 you are a normal person then, good
That was definitely one of the best videos like this I've ever watched. Super informative and she's just so fun to watch
Never seen a person enjoy what they do so honestly and purely :D Even my sour face couldn't help but smile when she did her experiments. She's a role model! Can't wait to have her on again!

yap exactly what I think it looks like
She is a great inspiration to learn chemistry. Her enthusiasm is contagious.
As an engineer working in oil, gas, and petrochemicals, and working with many chemists and chemical engineers... I have to say, her enthusiasm is fantastic and wonderful!
I love how excited she gets with every experiment. She should have her own TH-cam channel.

I wish they would’ve shown the scene in breaking bad where Walter throws this crystal down and it blows up everything. I would’ve liked to have heard her thoughts on that but amazing video either way!!
Her energy for the things she does is awesome. I can tell she loves what she does
I love that she also replicates some of these experiments instead of just explaining what they're doing :) I always loved science at school for the practicals ^_^
