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.

What does it teach?

Learn about mixing colors as the primary-colored crystals blend into secondary colors in the tube. Discover how these thirsty polymers perform very important functions in everyday life. They're used in everything from baby diapers to environmental cleanup materials!
