Mercury:
"Back in 1972 (October issue to be precise) National Geographic Magazine published a photograph of a man sitting on a pool of mercury. And I do mean on, not in. I've never forgotten that photo, and finally dug it up again (from their CD-ROM collection):
Of course, no one in their right mind, then or now, would expose themselves to this much mercury. But, man, doesn't it look like it would be an incredible experience? Mercury is so dense, and clings to itself so strongly, than the man floats on it like styrofoam floats on water. The pressure inside a pool of mercury rises 13 times more rapidly than the pressure in a pool of water (because it is 13 times more dense). Imagine sticking your arm straight down into a pool of mercury: The pressure on your hand would be as high as if it were 20 feet under water. What must that feel like?"
Coolest. Thing. Ever.
