Giant Crystal Growing Lab (National Geographic)

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.Each set includes a crystal cluster, crystal powder, crystal stand, magnifying glass, adventure guide (with some facts and info about crystals) and an activity booklet with puzzles.While the kits are quite bare-bones, they do produce some of the cleanest-looking crystals I've seen.
