Great for ooey, gooey color mixing fun! These amazing pebble-sized polymer crystals mysteriously grow into huge pieces of gel-like material when you add water. In fact, these crystals absorb 150-300 times their weight in water! Because of their incredible thirst, they're even used to reduce the amount of water needed to water crops and gardens during years of drought! Included with each package of crystals is a science activity guide, with lots of fun ideas for science projects. Ages 6 and up.

What's included?

• Superabsorbent crystal polymer
• Science activity guide

Pick your favorite color or pick all three!

How does it work?

Soak the crystals in water and see how fast they absorb water! In just a few minutes you'll have a huge bowl of icy looking crystals, only they're not cold! Dry them out on a paper towel, and you can use them again!

What does it teach?

Discover how polymers perform very important functions in everyday life. They're used in everything from baby diapers to environmental cleanup materials! Aside from their environmental and industrial uses, super-absorbent crystals are a great way to teach kids about color and light!
