As seen on the Ellen DeGeneres Show and the 2008 National 4-H Youth Science Day
Also known as slush powder, this powder instantly turns a liquid into a solid. Sodium polyacrylate absorbs from 800 to 1000 times its weight in water and is actually the secret ingredient that's used to absorb "liquid" in baby diapers! Includes a science activity guide with lots of fun polymer tricks to play on your friends! Water Jelly Crystals are an example of amazing Hydrogels... superabsorbent polymers that are saving the environment. 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.
What Does It Teach?
Water Gel at work in the world is a superabsorbent polymer, or Hydrogel, that's used as super-effective way to hold liquid in baby diapers. Superabsorbent polymers in their crystalline form, are used to help farmers retain water in their soil in times of drought. Learn how polymers are used to lessen the effect of environmental disasters on animal and human life.
- Water Gel 100 Gram Jar Review by Danae
The Water Gel / Slush Powder is a super absorbent polymer with the scientific name of Sodium Polyacrylate, or Hydrogel. This powder turns a liquid into a solid within seconds. This gel absorbs about 800 to 1000 times its weight in water. If this product clogs your drain all you need to do is pour salt down the drain. (Posted on 5/31/13)
- Works great Review by Jenny Brown
This works really well in a cup. I tried it on a larger scale in a bucket and it doesn't gel as solidly or as quickly. It really ruins the trick when you turn it over and gel comes out. It's pretty amazing in a cup though. (Posted on 5/31/13)
- Liv It Review by Jack N Moss
Am satisfied with the quality of the material and the excitement it creates in a classroom environment of 9-10 year-olds.
Wish some of your items were less expensive e.g. artesian diver so that I could give some out to each of my small class of 11 students ( These are out-of-pocket costs for me since I volunteer my services to this poverty-level elementary school) (Posted on 5/31/13)
- Great idea Review by Bob
Water gel is a great investment for teaching science as well as providing top notch entertainment. I buy the product out my own pocket and have made repeat purchases. Be creative. Have a student pour water from another vessel into a small plastic cup with the powder already hidden inside. Claim that you can turn the cup upside down and the water will remain. Then place a CD case over the top, hold it tight, and turn it upside down. They will think that is "cheating." Then place the assembly on top your head and ask the class to hypothesize what would happen if the case were removed. With a towell in your hand (for effect), ask a student remove it. Hopefully you won't have as many anxious volunteers as I usually get, but the effect is dramatic. "Where did the water go?" Now that you got their attention you can use the effect to describe hydrophilic polmers. You can also experiment with some great hypotheses, such as "Dr Bob is crazy." Be creative - Water Gel makes it easy, memorable, and fun. Be aware that high schoolers love to play with the gel and sometimes toss pieces around. (Posted on 5/31/13)
- FUN, FUN, FUN!!! Review by Kathy Storer
This stuff is truly amazing! We got it to play pranks on our family and friends. It's so much fun, especially when you're pretending that you're going to pour water onto someone and nothing comes out. They jump, run, and sometimes scream to get away! Hilarious! You'll love it! (Posted on 5/31/13)
- Great product Review by Judy
Like many of your other polymer products, the classes are always excited by the demonstrations or experiments. You've got all bases covered when it comes to polymers for kids! (Posted on 5/31/13)
- Amazing Water Gel Review by Judy Hamilton
I loved to see my grandchildren's faces when they experimented with the water gel. I plan to use some in potting soil this winter (in my greenhouse) and next spring too!

- STEM Student Expo Review by Thomas Hollen
I have used the water gel several times in a Fluids class to show that things are not always what they seem. But at the STEM expo, my associate brought the water gel and Instant Snow. He impressed a lot of students. I had the water crystals, so between us we showed the students what polymers can do and how the react with water. Our demonstrations werew a real success.

- Water Gel Review by Chris White
This is a fun trick to play on friends. This would be fun for april fool's day. My preschool class loves to watch the water gel. And they love to feel it. Nice way to teach kids about polymers. Funny to watch a kids reaction when you tell somebody where they can find the powder. A baby's diaper. (Posted on 5/31/13)
- Awesome! The students loved it! Review by ProfW
Had 4th and 5th grade students in groups of 2 compare the insta-snow and this gel. They loved it! Put 1/4 tsp in a cup and added 6 oz of water and then a blue scoop of insta-snow in another cup and added 2 oz of water. The kids loved watching the polymers pop up and compare the 2. (Cups were 9 oz clear plastic) Used less than 1/2 a jar and did 25 demos! Lots of product for the money. (Posted on 5/31/13)

- 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.
- Can I reuse it?
Yes, after you are done with your experiments, spread the polymer into a thin sheet to let the water evaporate. In about 2 weeks the powder will be back to its original powder form.
- 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!.
Material Safety Data Sheets (MSDS)
Most teachers are required to obtain an MSDS on every chemical in their classroom. Without proper training, however, MSDS information can be quite intimidating and could possibly lead a person to the wrong conclusion about the safety of a product. For example, would you consider water to be a safe chemical? Sure it's safe... it's water! But try reading the MSDS on water and you might be surprised. "FIRST AID: Call a physician, seek medical attention for further treatment, observation and support after first aid. Inhalation: Remove to fresh air at once. If breathing has stopped give artificial respiration immediately." Sounds frightening... and it's just water! If you request an MSDS on any product, make sure you understand what you're reading beforejumping to any conclusions. Any chemical can pose safety concerns (yes, even water). The best advice we can give parents, teachers or any adult supervisor is to read and follow the directions carefully. Look for phrases like "non-hazardous" or "not expected to be a health risk". If you have any questions, pick up the phone and call. Most importantly, if an accident happens, seek help immediately.
