Last week, we had the opportunity to try making bouncy balls. It was super easy and worked pretty well.
The idea comes from the 36th Avenue blog.
All you need is:
The bouncy ball probably bounced about a foot off the ground and our ball took a little while to start bouncing. We had to play with it quite a bit before it would bounce (I am not sure if this is because of the humidity or not). Ethan loved making a bouncy ball and we played with it for the remainder of the day until it was permanently squashed and unable to be remolded into a ball.
This is something that you could definitely do easily in the classroom too! :) Check out Fourth Grade Frolics for more fun ideas!
