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!

That’s a great question. I think they could help. Since the purpose of the crystals is to hold on to the water, it will help to keep the ground somewhat wet and less like to be blown away on windy days, depending on how much you use. To be fair, we have not tried this ourselves. It’s a great experiment, though!

If you use it in a bathtub or a sink would it cause it to clog up? Also the fizzes would it cause Staining in the bathtub or sink?
