Kosmos grow crystals

New breeding methods and a wealth of experimental materials - this large crystal growing set from Kosmos is full of creativity and possibilities. Children aged 10 to 14 can create their own sparkling world: iridescent single crystals form overnight, glittering crystal caves are made by hand, plaster figures can be coated with a magical, crystalline shell, and as a highlight, glow-in-the-dark crystals sparkle in the small treasure chest. The instruction booklet of the experiment kit explains with clear images how to create these wonders in various experiments and shows how to influence the size, colors, and shapes of the growing crystals or grow them on a thread.

The follow-up pages of the instructions provide a wealth of information about natural crystals. It's a creative and exciting way to discover the STEM science of chemistry.
