National Geographic - Crystal Lab (purple)

Grow crystals in your kitchen in five simple steps! These kits are among the most efficient I've seen, not bothering with frills or unnecessary components.All you need to do is heat up water, pour it into a container, and add the crystal powder and seed crystals. After 3-4 days of undisturbed rest, the crystal will form into an immaculate crystal cluster with its signature color.
