Hg-mercury-80

$36.00

Fun facts: The only metal that’s liquid at room temperature. Once used in thermometers, hat making, and mystical medicine—none of which aged well. Quite toxic. Named for the Roman messenger god. Hard to get a hold of, not that you should try.

Great for: Mythology buffs, fans of the planet Mercury, vintage science fans, and anyone who can’t be pinned down.
