The Giant Glow-in-the-Dark Geode brings the science lab right into your own room. Watch as the glow-in-the-dark crystals seemingly grow right before your eyes! The Geode kit includes a mold and casting plaster which allows you to create two Geode halves. Have fun learning about the formation of crystals, while watching as the entire process completes in about two to three days.

During the day these giant geodes glitter with brilliant crystals. When the lights go out at night they glow eerily in the dark. Making these giant geodes is fun and you’ll have a dramatic crystal display whether the lights are on or off.
