With this KOSMOS experimental kit, a sparkling crystal is grown from crystal salt overnight. The highlight: when you buy it, you don't know which color will emerge, as the kit contains only one of three colors: violet, turquoise, or orange. This miracle of nature can subsequently be displayed in a small jewelry box.
Children playfully experiment with different solutions while growing the crystals, thus discovering the first aspects of chemistry. The easy-to-understand color manual explains step by step how the crystals are grown. For ages 10 and up.
