Make Water Disappear Like a Magician!

Amaze your friends while learning about hydrogels.

As seen on the Ellen DeGeneres show, and also known as slush powder, 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 lots of fun, hands-on polymer science tricks to play on your friends is also included. Recommended for children ages 4 and up.

How does it work?

When you add water to this superabsorbent polymer, it instantly turns from a liquid to a slushy solid. Each portion is one blue scoop, which measures to about 3 grams. There are about 33 portions in the jar.

What does it teach?

Water 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!

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.

Can You Reuse It?

Yes, you can reuse the Water Gel after you are done with your experiments. Just spread the polymer into a thin sheet to let the water evaporate. In about 2 weeks the gel will be back to its original powder form.

Science Fair Connection

Think about some variables like these that you might test:

Try altering the type of liquid you use. Make sure you keep all other variables the same, including the quantity of water gel. Then compare the gel forms that are created. Are they the same? Different?
Try using different temperatures of water. Time the reactions or compare the gel forms that are created.

These are just a couple of ideas, but you aren’t limited to them! Come up with different ideas of variables to test and give them a try. Remember, you can only change one variable at a time for each test. For example, if you are testing different water temperatures, make sure that all other factors in the test remain the same!

Frequently Asked Questions

How many portions will this make?

Each portion is one blue scoop, which measures to about 3 grams. There are about 33 portions in the jar.

Is it like Insta-Snow?

The polymers are very similar, but the molecules are linked slightly differently, which is why they react differently with water.

What activities can I do with this?

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