Galinstan is a family of eutectic alloys of gallium, indium, and tin which are liquid at room temperature, typically freezing at -19 C (-2.2 F). Due to the low toxicity and low reactivity of its component metals, it finds use as a replacement for many applications that previously employed toxic liquid mercury or reactive NaK (sodium-potassium alloy). Composition: 68.5% Ga, 21.5% In, 10% Sn. Its name is a portmanteau of gallium, indium, and stannum (Latin for "tin").

It can coat objects to make them conductive. It can coat glass to make mirrors. It can make low friction electrical connections.

Comes in 25 gram pre-package bottles
