Thioacetone's odor can render people unconscious. It has been described as "fearful". No joke, read the Wikipedia page. Pretty gnarly stuff

I don’t get it; if AA can’t be moved or touched without exploding, how did they discover the rest of the stuff on that list?

Don't forget dimethylmercury. A chemistry professor spilled one or two drops onto her latex glove and it killed her a few months later.

When the ton of ClF3 spilled, it was inside a metal building, like a storage shed. When ClF3 decomposes, or burns, it forms hydrochloric acid and hydrofloric acid, and the two combined to ‘instantly’ corrode the entire building, besides having a large hold burned in the concrete.

If you want to learn more about ClF3, I suggest the book ‘Ignition’, which deals with the history of liquid rocket fuel. It talks about the accident, and lots of other exciting stuff.

I would just like to point this out to the scishow crew, in reference to azidoazide azide:
"This term is not a real chemical name. The blogger Derek Lowe made up this term as a joke when referring to "1-diazidocarbamoyl-5-azidotetrazole". The joke name azidoazide azide has, however, been used since then, sometimes jokingly in imitation of Lowe, and sometimes apparently without realization of the joke origins of the name." This is from Wikipedia.

Has the military ever thought of using thioacetone to disperse enemy combatants? I feel it would be more effective than bombing and would cause less casualties, given it is not a poison or disease would it be banned based on the Geneva Convention?
