You should smell my crotch, its actively working on producing a new element, even now unfinished you can smell it under water and wake up dead people. Every time I put on new underwear, I never see them again. On my latest job interview the guy could not stand the odor, and it was a phone interview.

Whats going on in the LAB Jim??? I heard Alarms. Ah nothing we just managed to set the fire on fire again with the this new chemical we created.........tried to put it out with more fire but it caught that fire on fire so we're just letting it do it's thing in there. Figured it would be cheaper to build a new Lab then try to cover this one up, and the boys at Dupont thought they got in trouble for Teflon C8 and C6 mess, we'll never hear the end of it. Na, just call that number from the comments bellow and get some of that N-STOFF junk that'll clean it up.

Another one the germans made was hydrazine. They tried to use it as plane fuel which resulted in blown up planes.

Thioacetone is not a thiol. A thiol, as you said is C-S-H. It is the sulphur analog of an alcohol (which would be C-O-H). Thioacetone is a thione, a sulphur analog of a ketone. Ketones have C=O bonds and thiones have C=S bonds.

WATER is the most dangerous chemical. You can drown in it, it is the universal solvent, drinking too much of it can kill you, not drinking enough of it will kill you .... Water. It ought to be banned. There should be warning labels on it. Frozen water is even worse. Broke my leg once on frozen water 😢 so slippery. My aunt died in a snow avalanche (so it's not all bad).

Thioacetone sounds like it could have some real applications as a safe area non-lethal weapon. Rather than bombing some rebel stronghold to pieces - you would have to imagine that permeating the area with the most godawful, instant-nausea smell known to man would massively demoralize and incapacitate solders within days if not just hours. And if you just need a couple of canisters to do that job then it seems like it would be stupidly effective. Seems like it would make an excellent riot-control weapon too that it would be much less violent than high-pressuring hosing, rubber bullets, tazers and tear-gas. Nothing kills your will to fight as much as extreme nausea, and this would certainly disperse and deescalate more than force that just riles up the crowd further. (Not that I support suppressing peaceful protesters of course, but sometimes such tools are legitimately needed and we might as well have them be the least harmful possible). This is assuming it's not overly harmful in some way not mentioned in the video overview though...

MUCH. MORE Rookie: what is your most recent attempt Scientist: I put it into a shock proof, light deprived, airtight, climate controlled room and it has not blown up sense Rookie: *well that great.* how long ago was it Scientist: 10 seconds before you got here *loud explosion blast a door off it’s frame* Scientist: *sobs into table* Rookie: okay i’l come back later *walks out the door* *THE END*

One minor mistake: thioacetone is a thioketone, not a thiol. Those are different organic functions. https://en.wikipedia.org/wiki/Thioketone

azide is funny. we used to put iodine crystals on the bottom of some ones shoes, then spray with ammonia, when the crystals dry out they become explosive. when they walked they were making little mini explosions like lady fingers.

For the most awful smelling, Pyradine must be near the top. Honourable mentions for going boom: Picric acid and Sodium Azides. The Sodium Azide as you can see for the other azide mentioned in the video, likes to go boom if it builds up say in a sink drain pipe array, and one day BOOM! Picric acid, heh, is a Medical Laboratory Scientist's curse. So many lab test still need it! Well It is kept in an airtight container with the crystals under a layer of water. Why? You simply NEVER want it to dry out. Once dry, just a slight jostle and POW!

azidozine azine is very relatable -most explosive compound on earth -very reactive because it mainly just wants to be "left alone" -stuck in a loosely bound high energy state, wants to get to a lower energy state by any means necessary -too sensitive to measure how sensitive it is

Should Francium be on this list somewhere? My understanding is that, as the most alkaline metal, it should be super willing to give up that last electron to pretty much anything.
