Author RobotSchipperke ( ago)
I thought botulinum toxin was the most toxic substance, with the lowest LD50. Is dimethyl cadmium more toxic?

Author Robert Raupp ( ago)
Very good episode. Made me laugh

Author Miles Flaherty ( ago)
I Think That Why C2N14 Exploded By Nothing, If Any Air Was Blowing into The Room (It Was Climate Controlled), Then The Friction Chould Have Caused it To Go Explode.

Author Hugh Janus ( ago)
I think I'd take the fart gas over the other ones but that's just me.

Author Sean B ( ago)
What's with there being so many German scientists discovering cool shit

Author Christopher Hereford ( ago)
How about links to seeing this stuff at work? It's all well and good to describe it but how about finding videos of cement on fire?

Author Are Elvestad ( ago)
No B-roll? OK :'|

So azidoazide azide is the school shooter of chemicals

Author Feriin ( ago)
Lol, Hydrofluoric acid is deadly, EXCEPT when the U.S. puts it in your water , then it magically becomes a nutrient...

Author Chris A ( ago)
Greek fire!

Author HolyFlame Dragon ( ago)
#3 Yes because someone can die now then die later, then die after that, then finally you stop dying by the onset of death. Makes sense.

Author Deinonychus194 ( ago)
"If I worked with Azidoazide Azide, waking up every morning and seeing that I still had all my fingers would be a very exciting discovery"

Author Dany St-Gelais ( ago)
this pop up in my recommendation after syria chemical attack xD thanks youtube I can make my own now

Author Metal Jacket ( ago)
One of them should be a random fat guy's fart.

Author Archibald Mirenopteryx ( ago)
Great video, from a biochemist and organic chemist. The identities actually surprised me: I was expecting methylmercury to make the cut - that stuff is also extremely poisonous, for pretty much the same reason as methylcadmium, and it actually resulted in a death not long ago.

Author C Cartoons ( ago)
Let's put them all together!!!

Author watts300 ( ago)
Great episode.

Author Donkeyearsa ( ago)
Where can i get a few gallons of that thoacetone? I can think of a few places around the collage dorm rooms that I can have some fun with it.

Author Tamisin 731 ( ago)
I dunno why I keep coming back to this video. I guess I enjoy explosives and science.

Author SuperKimxD ( ago)
Thioacetone must smell like Switch cartridges taste.

Author Tino TheKid ( ago)
Why does Germany 🇩🇪 make so many dangerous chemicals

If you have just a basic understanding of chemistry, this video is freaking hilarious

"The cement was on fire" best quote ever 😹

Author GeneralHands ( ago)
Anyone else find his voice and tone really fucking annoying?

Author Erin Fury ( ago)
So let's not show how to get laid nor how to not know wiki

Author Timmy Tide ( ago)
Could it be that Germans are kind of.. chemistry obsessed? just think about Justus Liebig.. He set the way for silver mirrors

Author notaseagull ( ago)
Smallpox has a single chromosome, which is 1 big molecule. It may be possible to revive smallpox with just 1 well placed copy of its genome in a receptive cell. At the very least, it wouldn't take a whole lot of them to reconstitute a viable culture in a dish, which could be used as a weapon. The limits of biological agents are usually more dangerous than chemical ones because they are self replicating.

Author [iX]smasher ( ago)
I laughed like 🤣 when he said the concrete was on fire!

Author Mud Kip ( ago)
When something *eats through the fume hood*, you know that there is no way it's safe.

Just after he said "one shoe scuff away from ka-blammo" I slipped on a stray lucky charm. Needless to say it scared the sh!t out of me

Author isaiah orozco ( ago)
Take my subscription!!

Author animist channel ( ago)
Okay, I'll throw this out there. Some maniacs with a super-cooler actually mixed up di-flourine dioxide: F-O-O-F. If you can still find the paper online, it's a fun read. Much of the article is dedicated to how many ways it goes BOOM. One gets the impression that a certain amount of equipment was sacrificed in the process :)

Author Keyreaper HAVO ( ago)
eats through glass like its cotton candy😆😆😆😆😹

Author AwesomeEB ( ago)
what would happen if you eat azidoazide azide?

Author Sharp knife ( ago)

"its too sensitive to measure how sensitive it is"

Remember hearing stories from inorganic chemists about shock sensitive materials. Prepare to lose some fingers

why not get teflon labware and go at it?

THE CONCRETE IS ON FIRE!!

Author Goriaas ( ago)
What is it with the pacific northwest accent that makes it seem like the people are speaking to you in a way they would speak with 3 year olds...

I don't know if I'm the only one feeling this way, but I know multiple people from the Seattle and Vancouver area that give me the exact same vibe

Author Grey Wolf Alpha ( ago)
OMG this is funniest educational video ever. !

Author Martin Ivers ( ago)
thioacetone isn't a thiole, but the sulfur analog of a ketone.
