What about trichlornitromethane and the pseudo-halogenic compound cyanogen.
King Slade (3 days ago)
Now then, the big question. Where can I get this stuff and how much does it cost? I got some names in a notebook here that need to be erased cuz they are taking up too much room 😇
Beau Davis (3 days ago)
"Absolutely nothing" Wow! I thought that there was no way that a material could exist that could blow up with no one even remotely touching it. That is absolutely, ridiculously unstable stuff. No, thank you. Keep me a 1000 miles away from the stuff before it decides to blow up for no reason. I thought that antimatter was bad. This is even worse than antimatter.

Doesn't cyanobacteria, nature, break down nitrogen triple bonds? Also did you mean that the nitrogen triple bond is hard to break or that all triple bonds are hard to break because nitriles are pretty reactive.

Holy hell how do they even make most of this stuff? Like the Azidoazide azide and the last acid? Humans...they're a lot smarter. Scratch that. Some humans...they're a lot smarter than other humans give them credit for. I would say the people who managed to create 5 of the world's most dangerous chemicals are, but they created 5 of the world's most dangerous chemicals. So there's that.

Is it weird that I have rewatched this more times than I can count. I love this video. Hilarious and informative 😂 "even the germans were like,...woah"

It was probably a stray cosmic ray that passed through the azide to make it explode.

So how the heck is "AA" able to be synthesized in the first place if it's so unstable?

SciShow , where did you find the information about dimethylcadmium, because i had a hard time finiding anything about the toxicity
Ken Seehart (14 days ago)
But dihydrogen monoxide, a common industrial solvent, has killed far more people than all of the substances in this video combined!

Used the elemental symbol for Cobalt (Co) instead of Cd in the formula for Dimethylcadmium. Slaps forehead. This is what happens when you let amateurs "teach" science.

everyone is talking about the AA, what about the fluroantimonic acid? sure AA explodes when nothing happens, but this acid eats through all but one substance. look up superacid vs fruit, watch some videos, and imagine that but millions of times worse.

I'm sick. Every time I watch this video I laugh my a## off. It's Hank's delivery but also, the thought of people sitting around saying "Let's put together something that blows up no matter what you do with it." :-). I would love to hear what Professor Sir Martyn Poliakoff has to say about azidoazide azide.
