mercury. i've been pondering a HAZMAT suit and a swimming pool full of the stuff. a metal that's a liquid. that can tell you the temperature. and it's poison?!?!?! other precious metals are bullshit, fort knox should've been full of toxic mercury. the extraction process is crazy too, they bake this rock called 'cinnabar' until mercury vapor comes out. then it cools into a liquid. i'm amazed it was discovered to begin w/. i also am amazed that cultures the world over all discovered bread.
