Description
Heres a fun, simple science experiment in a big plastic test tube!
Mix up some fast-forming crystals that produce heat!
The Sodium acetate solution forms crystals that look like ice, but are actually hot when formed and can be molded into shapes. Chemically safe and awesomely interesting!
