What about dimethylmercury?

Iryanmadayana . 2019-02-21
While dimethyl cadmium is extremely toxic, and it is way more dangerous by virtue of its other fun properties, I am pretty sure that it is not as toxic as some other compounds. Specifically, some biological compounds produced by microorganisms, most notably botulinum toxin. You know, the stuff that people willingly inject into their skin in order to kill parts of their face so that it won't be as wrinkly.

Hank, I know this comment is 10 years too late...

But I love this episode. One of the funniest SciShow have put out....

My fav part...

Azidoazide-Azide explosively decomposes when: ‘left Undisturbed on a glass dish’

Brilliant comedic delivery!

Thioacetone sounds like a weaponizable chemical. An enemy army can't fight if it's vomiting.

Dimethyl Cadmium Peroxide sounds even more deadly than Dimethyl Mercury (which probably would have made this list if it had been the top 6 instead of the top 5)

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.

I’m surprised botulinum toxin type H wasn’t on here THIS is the most toxic chemical known to man
A amount of 1 red blood cell of this toxin can kill all 40 trillion cells in your body
