This simple toy provides endless entertainment – the bouncy ball! When your child spots one in a gumball machine, he likely clamors for a bit of change. You spend the 25 or 50 cents only to later find the ball has bounced away into the twilight zone where lost bouncy balls live, probably never to be seen again.

Imagine if your youngster could make their own bouncy ball? Scratch that. Imagine if he could make a WHOLE BUNCH of bouncy balls? Then you’d never have to worry about finding the one that got away because there would be countless more to take its place. In this activity, you will not just make your very own bouncy balls at home, but your kids will also learn how polymers are made.
