Making Crystals In 15 Seconds

A seed crystal is dropped into an unstable supersaturated
solution of sodium acetate NaC2H3O2 and it completely
crystallized in front of your eyes. This chemistry more... more...
demonstration is prepared by heating 700 grams of sodium
acetate in 50mL of water in a flask until all the solid
dissolves. The solution is then cooled back to room
temperature. Drop a seed crystal and see the very cool
results.
