Sculpting in Solid Mercury using Liquid Nitrogen


Boing Boing Video teams up with PopSci and Theo Gray (in 2009) for an eerily beautiful science experiment — how to cast solid, if fleeting, shapes from normally liquid mercury — just keep it at 320 degrees below zero, with liquid nitrogen.

We love seeing examples of the elements’ different freezing and melting points. Because of Mercury’s toxicity, this one is especially interesting.
