Glowing Crystal Geode, Project Kit

Product Description: 

• Create your own crystal geode — a round rock containing a crystal-filled cavity. 

• First, cast a plaster geode shell in the mold and then fill it with a crystal-growing alum salt solution.

• The crystal solution contains an ultraviolet-luminous pigment that gets incorporated into the crystals as they form, resulting in a geode that glows in ultraviolet light. 

• An ultraviolet flashlight with holder, as well as a display stand for the geode, are included. 

• Learn about how crystals form and why the pigment glows under ultraviolet light.
