It's no secret that cigarettes are lethal. The CDC pegs yearly death rates from tobacco at a staggering figure of almost six million per year, and Villanova reports that a single drop of the drug in its pure form is enough to kill someone. With that knowledge, you might be surprised to learn that there are substances that are way more toxic.
There are substances that will explode with the slightest touch, and others that if you were to ingest a millionth-of-a-gram of it, you'd perish. Hank Green notes in the clip below that one of these was even deemed too dangerous by the nazis [emphasis his].
He runs through five of the most dangerous chemicals, but the most interesting of the bunch might be fluoroantimonic acid.
Hank prefaces the acid by identifying it as "the strongest corrosive agent in the world. The most dangerous acid ever devised by humanity."
According to Real Clear Science, this stuff is "100,000 billion billion billion times more potent than stomach acid," for whatever it's worth. They bring the figure into perspective by saying that sulfuric acid, well-known for its corrosive properties, is only "ten times more acidic than the contents of your stomach."
What's almost as surprising as hearing that such an acid exists is how mundane the storage process is. You know that wonderful stuff that lines your favorite pans, preventing stuff from sticking to them? Yes, you're remembering right — it's called Teflon.
Aside from its incredible nonstick properties, Real Clear Science notes that "Teflon is not only unreactive, hydrophobic, and 'non-stick', but it's also immune to a host of corrosive superacids."
