9. The Most Flammable Substance
8. The Most Toxic Poison
Quick, what’s the last thing you would want to inject into your face? Aside from something that burns through concrete, and maybe the world’s worst acid (coming soon), I would think “The world’s deadliest poison” would be in the top 3 with them. Not so, though, in the medical community; you’ve all heard of Botox, no doubt, and “deadliest poison” is it’s main claim to fame. Botox uses botulinum toxin, produced by the bacteria Clostridium botulinum, and it is so deadly, an amount equal to a grain of salt is enough to kill a 200 lb man. In fact, they even suggest that it would only take 4kg, properly dispersed, to kill every last person on earth. Maybe those crows feet around your eyes would be better treated with an angry rattlesnake….
7. The Hottest Substance Ever
6. Most Acidic Acid
Acid is scary stuff; they gave one of the scariest movie monsters ever acid blood to make it scarier than just a simple killing machine (the Alien), so it’s pretty ingrained in our psyche that getting dissolved is bad. If the Aliens had been filled with fluoroantimonic acid, they not only would have probably fallen through the floor until they hit dirt, the vapors given off by their dying bodies would have killed everyone around them. It is 21019 times more powerful than sulphuric acid, and can even eat through glass. And it explodes when exposed to water. And when it is reacting, it gives off poisonous fumes that can kill everyone in a room. Maybe we should move on from this one…

3. The Hardest Substance
1. The Most Super Superfluid
Superfluidity is a state of matter (like solid or gaseous) that occurs at extremely low temperatures, has high thermal conductivity (every ounce of it is always exactly the same temperature), and no viscosity. Helium 2 is the “most” example of this. A cup of He2 will spontaneously flow up and out of a container, as if it just decided to leave. It also seeps right through otherwise solid materials because its complete lack of friction allows it to flow through otherwise invisible holes that would not allow regular helium (or water for that matter) to flow through. He2 did not wind up at number 1 just because of its ability to act like it has a mind of its own, though, it is also the most efficient thermal conductor on earth; several hundred times that of copper. Heat moves so fast through Helium 2 that it moves in waves, like sound (and is fact known as “second sound”), rather than dispersion, where it simply transfers from one molecule to another. Incidentally, the forces governing He2’s ability to crawl walls is called “third sound”. You can’t get much more extreme than a substance that required the definitions of 2 new types of sound.
