Glow-in-the-dark crystal

Crystals are sparkling masterpieces of nature. And when they glow at night, the fascination is complete. With the Glow-in-the-Dark Crystal take-along experiment, boys and girls aged ten and up can grow a little treasure: A real rock crystal is covered with a glittering shell of alum crystals and glow-in-the-dark dye. This creates a large, artificial crystal cluster that shimmers mysteriously in the dark. The transparent treasure chest included in the set serves to store the self-grown showpieces.
