**These Jumbo Bounce No Bounce Balls are over 8x the volume of the standard Bounce No Bounce Balls!**
How Does It Work?
While the Jumbo Bounce No Bounce Balls look similar, their difference lies in their composition. The Bounce Ball is made of a rubber that has spaces in between its molecules. When the Bounce Ball hits the floor, the molecules compress and rapidly decompress creating a spring reaction. The No Bounce Ball is made of a rubber with smaller or nonexistent spaces between its molecules. That means when the No Bounce Ball hits the floor it will compress very little or not at all.
What Does It Teach?
The Jumbo Bounce No Bounce Ball demonstration is a one-of-a-kind, hands-on demonstration of molecules and their composition, but the possibilities don't stop there. Jumbo Bounce No Bounce Balls demonstrate effects of temperature on rubber, potential energy, and conservation of energy and make a great critical thinking tool.

We have had a lot of fun playing tricks with our look alikes. Students and adults have been surprised that they could look so much alike and be so different. Thanks for the fun. (Posted on 5/31/13)
