When you open the Jumbo Bounce No Bounce balls, you may think you've been duped or tricked. Don't worry, these balls are not the same.
 
Looking at the 2" diameter black balls, they appear identical. Both have the same size, shape, and markings… there is no difference! Try dropping them both on the ground. Now do you see? One of the balls bounces while the other thuds. It's not a trick - the balls are made out of two different types of rubber. One ball is elastic which bounces back. The other ball, however, is inelastic and lies lazily on the floor.
 
You've probably seen our standard Bounce No Bounce Balls... they're only 1" in diameter but perform the same as this jumbo version of the set. These Jumbo Bounce No Bounce Balls came from a partnership between Steve Spangler Science and the Gates Rubber Company. The balls are no longer in production, but we found a small stash in, you guessed it, Steve's Attic. So, whether you are a magician, teacher, presenter or trickster, get these one-of-a-kind Jumbo Bounce No Bounce Balls before they're gone forever. Recommended for children ages 8 and up.

What's Included?
  • One black 2" Bounce Ball
  • One black 2" No Bounce Ball
  • Activity guide

**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.

Customer Reviews

to Bounce or not to Bounce Review by diane

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 4/3/13)
