Grow dozens of beautiful crystals that glow in the dark with this luminous science kit! Experiment with dyes and glowing pigments, grow crystals rapidly and slowly, learn about the chemistry and geometry of crystallization, and check out your fluorescent crystal creations using the included ultraviolet flashlight. Mold 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 color combinations and mix the dyes to grow a rainbow of custom colored crystals. This kit is thoroughly tested and nontoxic. A full-color, 32-page experiment manual guides your experiments.
