Make Water Disappear Like a Magician!

Amaze your friends while learning about hydrogels.

As seen on the Ellen DeGeneres show, Water Gel turns from a powder to a gel in just seconds. Sodium polyacrylate absorbs from 500-800 times its weight in water and is actually the secret ingredient that’s used to absorb “liquid” in baby diapers! An Activity Guide with the test tube with water offers lots of fun, hands-on polymer science tricks to play on your friends. Recommended for children ages 6 and up.

How does it work?

When you add water to this superabsorbent polymer, it instantly turns from a liquid to a slushy solid.

What does it teach?

Sodium polyacrylate gel is the perfect way to demonstrate how polymers work. The gel is a superabsorbent polymer that can help illustrate how farmers can save their crops in times of drought and what kind of material is in a baby diaper!

A Picture is Worth a Thousand Words

Science teachers can talk all day about polymers and how they form and what they’re used for, but sometimes, just seeing them in action is worth so much more to young students who are aspiring scientists. Young scientists of age six and up can find that a picture is worth a thousand words with the Water Gel™ Test Tube kit from Steve Spangler Science. All they need to do is to pour some water into a cup with some Water Gel™ Polymer powder in it, and they’ll quickly see the polymer chains forming and soaking up the water as they look on in amazement. The kit comes with instruction cards for three experiments that teach the children about the many and varied properties of polymers so that they can begin to appreciate how these powerful compounds are used in hundreds of applications.

Super Absorbent Polymer Powder

Water Gel soaks up to 500 – 800 times its weight in water in seconds! It uses sodium polyacrylate – the secret ingredient used to absorb “liquid” in diapers!

Science Fair Connection

Turn Water Gel into a fun science fair project by simply identifying a variable (something that might change the outcome) in the experiment, then testing that variable, and correctly reporting the results.
