I know this has nothing to do with Mercury :)

Yes, I am aware now that I should not have been turning a jar of Mercury around in my palms, reveling is such a dangerously toxic element's beauty.
Mercury is interesting for numerous reasons. It is one of only six liquid metals and is the only one that remains a liquid at room temperature, which makes it uniquely variable in it's uses. Mercury was named after a planet, but it's chemical name is Hg which is derived from the Latin hydrargyrum (meaning watery & silver). It has one of the narrowest temperature ranges in it's liquid state and is worth discussing because it is a really beautiful element. cont...
