Make a Bouncing Polymer Ball - Experiment with Polymers. Introduction Balls have been toys practically forever, but the bouncing ball is a more recent innovation.
Bouncing balls were originally made of natural rubber, though now bouncing balls can be made of plastics and other polymers or even treated leather. You can use chemistry to make your own bouncing ball. Once you understand the basic technique, you can alter the recipe for the ball to see how the chemical composition affects the bounciness of the ball, as well as other characteristics. The bouncing ball in this activity is made from a polymer. Make Quick Sand. What you'll need: 1 cup of maize cornflour Half a cup of water A large plastic container A spoon Instructions: This one is simple, just mix the cornflour and water thoroughly in the container to make your own instant quick sand. When showing other people how it works, stir slowly and drip the quick sand to show it is a liquid. Stirring it quickly will make it hard and allow you to punch or poke it quickly (this works better if you do it fast rather than hard).
