Description
With this experiment kit from the 'Take-Along Experiments' series by Kosmos, sparkling green crystals can be grown independently. After just a few days, the first visible crystal structures appear in the growing vessel. An easy-to-understand instruction manual guides you step-by-step through the chemical experiment and conveys the fundamental principles of crystallization as well as the factors influencing crystal growth. The set also includes a practical jewelry box in which the successfully grown mineral shapes can be safely stored and attractively presented.
