483 - Cannonball floating in mercury
Tuesday, March 31, 2009




This incredible element is so dense that it can float a person with only a bit of displacement. (About 25 lbs per 1000 ml.) Even lead will float in mercury! (But not iridium, tungsten, or osmium.)

    nice to float on it, but I wouldn't do it without proper protection :P

    Do either of you know enough materials science or chemistry to explain to me why something so dense is a liquid?

    Never mind, I googled it and found a good site with that and more:

    I'm so tired. I should sleep. Tooooo much work.
