    Awesome vid, very entertaining and interesting. Question: At 5:11 he describes dimethyl cadmium as the most toxic chemical in the world, so toxic that a millionth of a gram can kill you. But at 7:04 he says it smells terrible. How could anyone know what it smells like if it's so deadly? Wouldn't a person die before they inhaled enough of it to actually smell it?

    The AA chemical probably explodes simply from heat energy. It will be impossible to store it unless its absolute zero.

    The name "azidoazide azide" is actually a joke. The real name of the chemical 1-diazidocarbamoyl-5-azidotetraazole. I just read that on wikipedia and am totally saying it now to sound smart.

    the problem with Ca-F bonding in humans isn't that your bones get eaten; it's that muscle contraction requires calcium, so if it's tied up in fluorine bonds, your heart can't beat.

    After a lengthy insurance claim to replace and install a new spectrometer, the team spent a great deal of time figuring out how to get the sample of AA into the machine without it detonating. A solution was found and the sample successfully and safely loaded installed into the new spectrometer to great applause. Figuring that the hard part was over, one team member turned on the new machine which instantly blew up. They learned an interesting fact that day, insurance companies have no sense of humor.

    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
