The Kid Should See This

Sculpting in Solid Mercury using Liquid Nitrogen

Watch more with these video collections:

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.

This Webby award-winning video collection exists to help teachers, librarians, and families spark kid wonder and curiosity. TKSST features smarter, more meaningful content than what's usually served up by YouTube's algorithms, and amplifies the creators who make that content.
