Product Description

Grow dozens of colourful 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 colours under the light from the included ultraviolet flashlight.Mould fun plaster shapes, including moons, stars, butterflies, neon signs, mushrooms, frogs, and gemstones, and then grow layers of crystals on them. Use dye tablets together with the glowing pigments to experiment with different colour combinations, and mix the dyes to grow a rainbow of custom coloured crystals. Mould your own glowing crystal geode a hollow rock lined with crystals and create a beautiful crystal cavern inside.
