Magnetic Tennis Balls

These balls look like ordinary tennis balls, but they are hiding super-powerful Neodymium Magnets! When the two balls come close to each other, they stick together! Unprotected, these Neodymium Magnets are so "attractive," they'll knock iron chips off each other if they get too close! That's why the tennis ball disguise makes it safe for even the youngest scientists. Magnetic Tennis Balls are perfect for Discovery Centers. Each set contains 2 balls. Recommended for children ages 8 and up.

How does it work?

Neodymium magnets also contain Iron and Boron, making them some of the strongest magnets in the world. Magnets of all types create a magnetic field, with both a north and south poles. The magnetic field created by the neodymium magnets is so strong; if you throw the two tennis balls in the air, they'll stick together! Once you start playing and experimenting with them, you'll never put them down!

What does it teach?

Teachers and older students can use Magnetic Tennis Balls to demonstrate the "attractive" forces between molecules (hydrogen bonding, for example). Younger students discover the science behind magnetic fields, friction, and the magnetic poles of the earth.
