These Amazing Pebble-sized Polymer Crystals Mysteriously Grow into Huge Pieces of Gel-like Material!

Just 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 an activity guide with lots of fun ideas for science projects. Water Jelly Crystals are an example of amazing hydrogels… superabsorbent polymers that are saving the environment. You can also color them for amazing results!

How does it work?

Soak the crystals in water and see how fast they absorb the 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. Sometimes referred to as hydrogels, they’re used in everything from baby diapers to environmental cleanup materials! Aside from their environmental and industrial uses, superabsorbent crystals are a great way to teach kids about color mixing and light!

How Long Do They Take to Grow?

The crystals grow in less than a day, so if you throw them in water before your students come to class, they should be ready for your little scientists to play with after lunch.

Is This What They Put in Flowers?

INDEED!! Using jelly crystals will help to reduce the amount of watering that you will need for your plants during the planting season.

What Temperature Should the Water Be?

Through all of our rigorous testing, we found that they crystals grow better in warmer water than they do in cold.

Frequently Asked Questions

In the color packs, can I pick the colors?

No, the packs are created with color mixing in mind. Our clear crystal packs are limited to being clear. The three and four packs both come with the primary colors – perfect for color mixing! The four pack does include clear as well in case you’d like to try your hand at coloring them yourself.
