Dramatically demonstrate crystallization and release of latent heat.This fascinating hands-on experiment utilizes a patented 4" x 4" pouch of super-cooled sodium acetate to visually demonstrate crystallization and the subsequent release of latent heat. Indefinitely repeatable, simply boil and cool the pouch to return its contents to the super-cooled state. Best of all, you can use it to introduce conservation of energy to students of all ages. The instruction manual (included with Supercooled Lab Demo) covers history, practical applications, and suggestions for qualitative and quantitative experiments.
