This large crystal growing set 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, and plaster figures are coated with a magical, crystalline shell that sparkles in the little treasure chest. The instruction booklet of the experiment kit explains with clear images how to create these wonders 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 lies behind it? It's a creative and exciting way to explore STEM sciences.
