Also known as slush powder, this powder instantly turns a liquid into a solid. 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! Includes a science activity guide with lots of fun polymer tricks to play on your friends! 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 is a superabsorbent polymer that’s used as a 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.
Science Fair Connection
While playing a prank on your friend is fun, this activity isn’t a science fair project, yet. You can make it one simply by identifying a variable (something that might change the outcome) in the experiment, then testing that variable, and correctly reporting the results. 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!
