Glowing Crystal Geode
Make a beautiful crystal geode that glows in UV light!
Create your own crystal geode--a round rock containing a crystal-filled cavity. The crystal solution contains an ultraviolet-luminous pigment that gets incorporated into the crystal 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.
