Giant Glow In the Dark Geodes
No. 219
Ages 9+

This is the first and only glow-in-the-dark geode kit. Imagine turning out the lights and seeing the eerie glow of your giant geodes – their hollow orbs glittering with glowing crystals. The kit includes a mold and casting plaster for two geode halves, glow powder, growing chemicals, and a science guide. Your giant sparkling geodes will sprout with glass-like glowing structures, growing realistic crystal formations in two to three days. Great for science fairs and family learning.
