Biology has its fearsome animals, bacteria and viruses, and physics has its mind-bendingly powerful forces. But let’s not forgot how utterly terrifying chemistry can be

This video from SciShow explores the deadliest and most dangerous chemicals known to science. Among the chemicals are the highly volatile, the ridiculously toxic, the stupidly corrosive, and the one chemical so dangerous the Nazis decided it was too scary.

But if you thought all these chemicals are now banished to the past or some high-security laboratory, you’re wrong – some of these chemicals still have their uses today. Maybe all those fumes have finally got to those chemists' heads.
