Now that the The Prof has the box set - feel free to request any specific chemistry-laden episodes you'd like him to watch!!!

[@churchofthelambofsat]

Season 1 episode 6.

[@mobiousenigma]

professor p! as always thanks for the videos. i suspect there will be many chemical inaccuracies as you watch mainly to keep series producers out of court. it is as you say fantasy make believe which bears a striking resemblance to our realities. tv like the internet can be used as a source of knowledge or information but the sources still require vetting.

[@Slothery]

In the episode titled 'Box cutter' right before the guy gets his throat cut, Walt asks a bunch of intentionally complex chemistry questions. There is also a lot of chemistry equipment throughout the episode.

[@alexandercz.4218]

Why didn't Walter White make the reagent chemicals (Methylamin) for himself? I mean he had an engineering lab and it should be less conspicuous to make these chemicals himself rather than to buy or steal them? I bet you can produce the reagent chemicals on your own and start "cooking" ...

[@mytech6779]

It is important for the professor to know that the producers purposefully made some of the chemistry details wrong to be somewhat socially responsible.

[@Gunbudder]

Vince Gilligan has stated that the chemistry was slightly altered in every scene showing dangerous or illegal chemistry. Essentially, they made the chemistry wrong on purpose so that if any viewer tried to follow the show, they would get no reaction, or something harmless. this is especially true for the meth recipe where they purposefully left out a few key steps and also show Walt doing a few things wrong on purpose.

[@ficolas2]

Ah yes, using HF to dissolve a body, certainly something harmless.

[@gastonbell108]

Mythbusters successfully recreated the effect on the show (partially anyway) with piranha solution, which is 18M H2SO4 and 20% H2O2. Nothing rare about the ingredients, just the effect they produce in tandem. The peroxide sends the oxidation into a frenzy, it's like liquid fire when it touches anything organic, even leaves black tarry residue behind like a fire. But even piranha won't dissolve a ceramic-lined bathtub. There's a reason so many things in a laboratory are made of porcelain.

[@davidmaisel8062]

@@gastonbell108 H2SO4 is nasty stuff and extremely unstable. I thought it was very irresponsible of Mythbusters to even show that episode.

[@rambo8wradio]

I've heard that is the same reason they altered some of MacGyver recipes in original series, so kids couldn't replicate him.

[@futurestoryteller]

That's a nice excuse, but actually that is literally _only_ about meth as they were instructed to make those alterations to retain the help of the DEA. As the Professor points out you *can* dissolve bodies in HF, and it will *not* eat through plastic, so they're not going to take creative liberties just so that would be serial killers and drug cartels can properly dispose of bodies, but _maybe_ it won't work exactly the way they expect, and they'll get caught through shenanigans, that's just silly

[@BobMotster]

The professor doesn't mind the laws of physics being broken but he gets livid when someone violates the laws of chemistry. Unfair

[@aminulhussain2277]

No, he minds presenting inaccuracies as real/correct.

[@MadScientist267]

I have the same problem but we're never going to see "accurate" chemistry, or any viable attack for that matter, in any Hollywood presentation. They can't legally tell you how to dispose of a body, for example. So they have to use chemical names that people associate with fear, and exploit the ignorance of the masses to get the suspension of disbelief working. For those of us that know the difference, we end up frustrated and disappointed. Just a necessary evil, unfortunately.

[@ratunkuuu]

That's sprcialisation!

[@ohsweetmystery]

He stated he doesn't mind if it is labelled as fantasy. Selling something as realistic and then falling short is very different than a story that is just about pretending.

[@skbirdandsiggi10]

couldn't they have bought them?

[@j.dietrich]

Inflatable pools are invariably made from PVC, which is susceptible to HF.

[@knottheory79220]

@@j.dietrich I was looking for someone to point that out. But the solid kiddie pools (non inflatable kind) are probably built out of the right kind of plastic, unless they're vinyl pools.

[@positronundervolt4799]

It's not even that it's the wrong type of plastic... Gotta remember the context of those 2 episodes; they're both freaking out. Neither Jesse or Walter were thinking clearly.

[@EebstertheGreat]

In some ways, the show fared better than I expected against the professor's criticism. But he's right that the school had a suspiciously enormous supply of HF and that the small amount Walter took would never be close to enough to eat through a body, tub, and floor.

[@themagnus2919]

What high school would trust students or even teachers to handle HF safely...?

[@MrSnoots]

Also, would a company like, for instance, Sigma-Aldrich not be suspicious about GALLONS of HF going to a high school? Would they need to report that?

[@Thermalions]

I've also never seen a high school with such a large and comprehensive supply of chemistry hardware and consumables. They're generally always struggling to just get a fair share of the funding.

[@BuIIetBiII]

No school I've ever worked in has had HF. It's far too dangerous.

[@pauljackson2409]

After much cajoling, the Prof. is becoming a Breaking Bad aficionado. Completely agree that concentrated HF is not something you'd find in a High School lab. There are some other howlers in the show, such as being able to light thermite with a blow torch, but in defense of Vince Gilligan and his excellent team of writers, they probably didn't want the show to become a 'how to use chemistry for criminal activities'.

[@quackerzdb]

I thought there was a sparkler fuse in the thermite. That would do the trick.

[@pauljackson2409]

@@quackerzdb Yes that would work, but if you watch the scene where they use thermite to melt the lock of a warehouse; they just blast some thermite in a plastic bag with a blowtorch and up it goes.

[@auracle6184]

That's correct, they deliberately fluffed a lot of the chemistry because they'd be on the hook if anyone ever tried to mimic the show using its own instructions

[@gg2324]

You need magnesium matches right?

[@filipealarza9079]

That's not hard to do. Just use a Mg strip as a fuse.

[@minikawildflower]

I think an explanation about the paddling pools is that Walter never asks Jesse for any information, he just comes up with a plan and orders Jesse what to do. So he immediately started yelling at Jesse to go buy a bin, without ever asking him "hey, do you have anything around here we could use." And he never tells Jesse WHY they're buying a certain kind of plastic, he just yells terms at Jesse. If he had said "HF will eat through everything except plastic," Jesse might have said "oh, I have a kiddie pool can we use that?"

[@Paul-kd3ui]

Great insight from professor. However, I think the showmakers once said in an interview that they are not really into 100% scientifically correct scenes for public safety reasons (and practical). However I would like to say that this shows popularity has definetly increased peoples interest in science and chemistry. It certainly inspired me to a few hour long wikipedia binge and science videos on KZbin back in the day.

[@bosstowndynamics5488]

Absolutely love imagining The Prof having a giggle at Jesse in the hardware store. As a side note, I'd love to see some videos of chemistry that would have baffled scientists centuries ago. Chemistry that is clearly understood today, but would have had alchemists convinced that transmutation was viable, for example.

@@WilliamFord972 When I used it, it had been mixed with clay slip so that you could glop it on something and it would stick even if not perfectly level.

I'd like to get the professor's opinion on whether or not Walt and Jesse produced an optically pure product once they had switched methods to reductive amination. There is never any mention of a chiral resolution in the show after they moved away from the Nagai reduction, so I think it would be ironic if all this time Walt's "Blue sky" was actually racemic and not that potent.

[@EebstertheGreat]

It's possible their "pure" product was inferior to what a lot of people can get on the street today.

[@conrad9race1]

yes, this is exactly what woould hapen unless they they somehow came up on method that converts purified version into more potent, which was metioned i tkink, but that reaction doesn exist or isnt known

I had a very similar thing happen to me recently, well not really all that similar but I got a call from my dad, he used a concentrated sulfuric acid drain opened on a totally clogged drain without taking any steps to protect the metal of the drain itself. It filled up, ate through the drain and then leaked into the cabinet below and onto the floor. What a mess. Ruined the drains, the cabinet, the floor, turned everything black. Always follow the instructions, you know?

[@ronblack7870]

probably a product called Clobber . it's sulfuric acid. usually works great . it will eat rust so if a cast pipe is badly rusted it can go through. never had it happen to me though. when you open or pour it you get the white fumes forming so it's the real deal.

[@gastonbell108]

I was told by my plumber that in the old days, people would regularly end up in the hospital with eye and face burns after pouring H2SO4 down the drain while standing over the hole looking directly down (despite the label saying specifically not to do that). It was so common that the modern stuff is all formulated so it doesn't heat up as quickly or as much - less effective on a tough clog, but less legal liability.

Amusingly, when the Mythbusters did this, they were equally unimpressed about the amount of flesh-dissolving when they replicated the feat using pigs. They eventually resorted to Piranha Solution, which worked significantly better (as we all know). What I want to know is, what would you have done, professor?

So, I think that "forgetting" about the plastic pools is not at all unrealistic, because both of them are amateur criminals, as is referenced later when they heist the barrel of raw material for their little...venture. It's one of the points of the story that in the beginning they're not adept at criminal stuff, so they're on edge and make mistakes. I can't remember if Jessie just owned these kids pools or Walter just forgot that there are other liquid holding items made of PE that they can use besides tubs. I think that's totally believable.

[@themathhatter5290]

I think the most interesting part is the Mythbusters tried to replicate this scene and the acid didn't eat through the tub, or at the very least, it didn't weaken the floor enough to break.

[@Physhi]

There are certain acids that you can make in bulk from on the shelf products which you can buy in bulk from certain stores in the US which can completely dissolve tissue and bone down to the DNA structure. I find it more unrealistic that the teacher didn't go and buy these products from different stores -- though the amount of people who watched that series *should never* be exposed in how to make such things for safety reasons.

[@TheMrfish14]

Prof , you lighten up my day every time i see you in a video. Thank you

[@ThZuao]

Dissolving bodies in HF was one of the tijuana cartels methods of disposing of bodies. A notorious one caught while the show was in it's infancy (2009) and very likely an inspiration for it in some way was El Pozolero, the Stew Maker (pozole is a kind of mexican meat stew), who admitted to dissolving more than 300 bodies after, you guessed it, bits of human bone were found scattered around his property. He used to dump bodies in barrels and ship them out as industrial waste. The undissolved bits were ground and used as plant fertilizer.

[@nuck-]

There is actually quite a few videos online of the "los zetas" dismembering bodies and placing them in acid to disolve them, i have watch them all myself. The drums they put the bodies in clearly said "sulfuric acid 70%" but they added something into the drums once the bodies were in them. I assume this was some sort of catalyst. The drums quickly boiled over onces this catalyst was poured in, they added about a half litre to the drum every minute or so. The body turned to a black mass pretty quickly. Gruesom stuff but for those who dont mind gore its very interesting. These things happen daily on our planet, its not a bad thing to leard about what your fellow species is doing.

[@ThZuao]

Everything they did to clean it just didn't work so in the end they tried the HF on it. It came up spotless but was no longer water proof!

One reason why you couldn't use the pools: they were probably made of PVC, which melts between 80 and 100°C, and can start degrading bellow that. HF reactions can heat up to far above that temperature

My exact thoughts when I watched the show: “How on earth did they manage to dissolve the tub, but not the body, using this tiny amount of acid?!” 😂 I also just realised they must have dissolved the floorboards under the tub as well, for it to fall through the ceiling like that…! Though I believe the producers kept some of it purposely vague, since the shows lawyers were quite worried about publishing an actual “how to dissolve a human body in your bathtub” tutorial. On a side note. I am always so impressed by Professor Poliakoff’s enthusiasm. No matter the subject, if he applies himself, he seems to do it with a great deal of enthusiasm. I really appreciate him sharing his thoughts and insights.

[@Toastmaster_5000]

I think it's plausible there would still be a lot of red blood left in the partially-dissolved corpse. Unlike the chicken, the gangsters weren't drained of their blood, and as pointed out, there wasn't enough acid to dissolve everything. So when they hit the ground real hard, it makes sense how the force could basically "eject" a bunch of red blood out.

[@rin_etoware_2989]

there's still the problem that it's *all* red. i imagine the scene would be that bit more believable if it was a mix of red, brown, black, and white.

[@Toastmaster_5000]

@@rin_etoware_2989 I agree, though considering there doesn't appear to be any documented case of anyone witnessing a corpse partially dissolved from acid falling from the floor, I don't think _anyone_ can really say what would accurately happen. The scene was dark enough that you wouldn't have seen much color variation while it was falling, and after hitting the ground, I think it makes sense for everything to be red, but we're not likely to find out. For Hollywood, they could've done a lot worse with realism.

Later when the lights were turned on, there was a huge explosion in the toilet that demolished the partitions. The school couldn’t identify the reason of the explosion and it didn’t have the toilet fixed for some time. So we used it with absolutely no privacy for a few weeks 😅 this was almost 30 years ago…

I remember stories from 65 years ago of an enterprising school physics teacher who got their school equipped with radioactive supplies and appropriate equipment to teach classes on radioactivity long before such classes became common (40 years ago, similar schools would have standard prepackaged educational sources of gamma, beta and alpha radiation, but not 65 years ago). So I find it plausible that a high school chemistry teacher could convince his school to purchase whatever exotic supplies he wanted as long as the overall budget was kept.

What a fun story. Any other fairytales?

[@IceMetalPunk]

Why did it only explode when the lights were turned on?

[@johnladuke6475]

@@IceMetalPunk That's how you know he's making it up.

[@jguo]

@@IceMetalPunk the lights were turned on and timed out after a minute or so. Probably the H2 gas entered the relays and got ignited by a load spark.

I loved my chemistry teacher he was wonderful and watching this professor explain this is as close as I'll ever get hearing my science teacher explain it so I'm so happy to watch this. Trait liberty video from a really great guy.

[@JP_Stone]

That's great. Love to see the Prof watching Breaking Bad and I hope we get some more episodes breaking down some of the other chemistry parts of the show.

[@irwfcm]

One thing to note is that later in the show they did switch to dissolving bodies in 55 gallon barrels using much more acid. I wonder if someone told them that was a more correct way to do it, like that serial killer did?

[@ericpmoss]

I laugh at how the characters remain faithful to the idea of “better living through chemistry”, when they had a giant desert with scavengers to work with.

[@jiioannidis7215]

For your next trick: mercury fulminate wouldn't explode the way it did in Tuco's office. Someone else already mentioned the problems with thermite. And a phramacology issue: would whatever poison was in the tequila be slow-acting enough to be partially absorbed by the presumably activated-charcoal capsules that Gus swallowed, and the rest vomited, so that it wouldn't be fatal.

[@HerculesRockefellerESQ]

If the fulminated mercury had exploded, the single shard, likely the rest of the bag would have too from the blast concussion, if memory serves me correctly.

Mythbusters proved this as false, but your actual chemical reason why is great! The fact you did this analysis is awesome! You have to admit, it was one of the best shows in modern times.

[@ayrts01]

no they didnt mythbusters admit at the very beginning of the video they are using a similar but different type of acid

[@maxime3648]

I've studied semiconductors and went through lab classes multiple times at university level... Never have I seen such a large bottle of HF, it's absolutely insane that a highschool would have any

I have a B.S. in chemistry. I’m currently doing my PhD. Is the chemistry exaggerated? Very. Is it a great show? Absolutely.

[@nuck-]

Could you add an oxydizer or a peroxide?

[@kcgunesq]

Of course, I trust the professor to know the chemistry and of course, it doesn't change any part of his analysis, but for American viewers, the jugs of HF are shown in what most would recognize as a 1 gallon jug. Many things, especially cleaning supplies like windshield wiper fluid or ordinary vinegar are sold in such jugs.

[@superdupergrover9857]

Those are standard American gallon containers, btw. In fact, that shape and size of bottle is used for *everything* but only rarely for drinks, now that I think about it.

[@killernor23]

Prof to help you out those are one gallon jugs of HF. The same style jug thats typically use for car window wash fluid. Very common here in the U.S but I agree he would need well over 25 gallons to cover the body. Most bathtubs are 50 to 80 gallons in volume. 2 gallons would just react with his underside or the bathtub.

[@LoveDoctorNL]

Great video going into detail. Could we also have a video with professor Poliakoff commenting whether he believes he (like Walter) could make the best and cleanest version of Crystal Meth? 😊 Does being a chemistry professor make you a better drugs producer?

[@clxwncrxwn]

Respirators are quite easy to obtain along with their various filters, one model I bought came with a vacuum sealed filter for various fumes or organic odours etc,

[@parcydwr2]

A great video. Have you done the experiment of leaving a microscope slide in HF for a few minutes and then bending the microscope slide? The acid removes all the scratches and flaws that would initiate a crack so you can bend a dipped microscope slide to a surprising curvature. Also... Yes films have loads of errors that I spot as an engineer. It does irritate me too. Rob

[@planetfox890]

Nothing more awesome than watching a kindly old professor talk about dissolving a corpse in acid.

[@jackielinde7568]

In defense of the "mistake" where Jesse puts the corpse in the bathtub fully dressed not knowing that HF wouldn't dissolve the natural fibers, I could see him making that mistake. Walter never told him to undress the body, and Jesse did fail Walter's chemistry class. Heck, I took chemistry in high school, and we never covered HF in our class. So while Walter (A professional chemist) should have known, it's completely understandable that Jesse didn't. Also, as someone who lives Phoenix, Arizona (kind of next door to Albuquerque, New Mexico), I can tell you that you'd DIE in an Albuquerque or Phoenix summer wearing 100% Polyester. While their shoes, belts, watches, etc. would be largely synthetic, their shirts, t-shirts, and jeans would be cottons or cotton blends. For example, the Wrangler brand of blue jeans I wear are 100% cotton. And it's the same for my t-shirts. While it would be ideal to strip the bodies naked for dissolving and washing everything else for donating to Gooodwill (a charity thrift store in the US), it's not like what we wear in the Southwestern US would pose much of a problem for HF. Now, when the HF solution "ate" through the bathtub, dumping the "solution" onto the floor below, yeah, there should have been things left over that HF didn't eat. That's completely inexcusable.

[@RedDawn370]

These are fair and well reasoned criticisms. Well done professor! We need more of these on Breaking Bad!

[@aperson2703]

I love that he's mostly upset that there wasn't enough HF. It's for the purpose of the show. Just imagine that he grabbed more HF later but could only grab two bottles at a time. Grabbing bottles from the school is also a plot device for later.
