How does it work?

Soak the crystals in red, blue and yellow water and see how fast they grow! In just a few minutes you'll have bowls of colorful icy-looking crystals, only they're not cold! Layer them carefully in your plastic test tube, and watch how many colors the crystals form when they blend together.
