Kosmos Growing KOO Crystals 645601

This large crystal growing kit is full of creativity and possibilities. Children create their own sparkling world: iridescent individual crystals form overnight, a glittering crystal cave is made from scratch, plaster figures are coated with a magical, crystalline shell, and they sparkle in the little treasure chest. The instruction booklet of the experiment kit explains with vivid images how these wonders are created through various experiments and shows how to influence the size, colors, and shapes of the growing crystals. And what expertise from the fields of geology, chemistry, and mineralogy is actually behind it? It's a creative and exciting way to explore STEM sciences.
