Educational Focus: Geology
• Grow your own crystal and display it on a color-changing light-up stage!.
• Assemble a special platform with a color-changing LED circuit inside.
• Learn about the chemistry of crystal formation and the physics of light and color.
• Includes a 16-page, full-color manual with step-by-step instructions and straightforward scientific explanations.
• For ages 8 and up
Grow dozens of colorful crystals, including two types of crystals that glow in the dark. Experiment with growing a variety of crystals from a potassium alum salt solution. Add strontium aluminate to your crystal solutions to make phosphorescent crystals that charge up in the light and then glow in the dark on their own, slowly emitting the stored light energy. Or try adding one of two ultraviolet-reactive pigments, pink and greenish-yellow, to your crystals to create fluorescent crystals, which glow in stunning colors under the light from the included ultraviolet flashlight.
