This kit will take you through various experiments and show you how to grow your very own sparkling crystals. You will also get to create your own glowing crystals and crystals that react to UV light. Mould fun plaster shapes, including moons, stars, butterflies, neon signs, mushrooms, frogs and gemstones, and then grow layers of crystals on them. 

With 12 included experiments, you will learn all about the chemistry of crystals. You will get to experiment with growing crystals rapidly and slowly, and observe how that affects the crystal structures. See if you can grow a giant crystal and lots of crystals on the surface of a rock. You will measure how the crystalisation of solids out of a solution, and the dissolution of crystals back into a solution, affect the temperature of a solution, and much more.
