How To Make Water Polymer Balls At Home

Cups, bottles, toys, source=SFGHG&utmmedium=referral&utm_campaign=8610'>shower curtain liners, food containers, CD boxes: look around and you will probably see lots of plastic in your environment. Plastic is a type of synthetic polymer, which is a substance made up of many repeating structures. Polymers also form natural substances, such as proteins, starches and cellulose. Manufactured polymers share many properties, including resistance to chemicals, insulating ability and strength. You can make your own bouncing polymers with ordinary household materials.

Step 1

Cover your workspace with newspapers or paper towels.

Step 2

Combine the borax and water in a plastic cup, then stir with a Popsicle stick.

Step 3

Add a few drops of food coloring, if desired.

Step 4

Add the cornstarch to the borax solution, then stir.

Step 5

Add the borax-and-cornstarch solution to the cup containing the white glue. Stir until it is very thick.

Step 6

Pull the mixture out of the cup. Knead and roll it into a ball shape. Continue rolling until it is relatively dry.

Step 7

Add more cornstarch, half a teaspoon at a time, if the ball is too sticky.

Step 8

Coat the outside of the ball with white glue for extra protection, if desired. Set the ball on wax paper while the glue dries.

Step 9

Store in a sealed plastic bag.
