Sturdy, clear balloons to use for the Spinning Penny experiment or fill the balloon with Styrofoam beads to make a static electricity detector! Contains 100 clear latex balloons, so plan to get a huge crowd of your students together and start spinning! The kids will love it, and they'll learn some important science principles at the same time. We'll throw in the Spinning Penny Activity Guide as a bonus... you provide the pennies. Recommended for children ages 6 and up.
What's included?
- 100 High quality clear balloons
- Activity guide
How does it work?
Hold the balloon with two hands and make a swirling motion. Thanks to the laws of inertia and centripetal motion, the penny flips up on edge and spins around the inside of the balloon just like that motorcycle guy at the circus. It's science and it's amazing!What does it teach?
The spinning penny science experiment is great to introduce kids to the laws of motion, inertia and force. When an object spins, a force is created which pulls the object outward, just as when you ride on a merry-go-round and feel yourself pulled toward the edge. Besides being pulled outward, as the penny spins, it pushes against the side of the balloon. At the same time, the balloon pushes back. This causes the penny to spin and move in a circular path.

clear balloons
Deb Leedom - March 18, 2010
I was excited to find that clear balloons were available for purchase online, as I was having difficulty finding any locally. Our physical science class performed the centripetal force penny experiment, as well as the skewer- through-the-balloon demonstration. The students loved the experiments, but were visibly disappointed when many of their balloons failed to hold air throughout the 45 minutes of balloon-time. Several balloons had small visible holes and were losing air before being tied. But the point of the experiment was clearly understood in a fun hands-on way-which we love!!! Thanks! Deb- |
