I thought botulinum toxin was the most toxic substance, with the lowest LD50. Is dimethyl cadmium more toxic?

Very good episode. Made me laugh

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.

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?

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

#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.

"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"

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.

Let's put them all together!!!

Great episode.

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.

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.

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 :)

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

OMG this is funniest educational video ever. !

thioacetone isn't a thiole, but the sulfur analog of a ketone.
