Original Gyro-Ring

Get the Gyro-Ring and amaze your friends. How Does the Gyro-Ring Work? The Gyro-Ring is really just five little tops of unusual design strung on a metal ring. Do you remember how tops appear to start "wobbling" as they slow down? This rotation of the spin axis is called precession and causes the ring to press on one side of the hole in the spinning top. The contact point between the ring and the top can be thought of as a gear that changes the motion of the upward moving ring into the top's spinning motion.

KaBlaster YoYo

With a flick of the wrist, set the balls in motion and witness Newton's classic laws of physics in action. As the first ball swings around, it always stops when it hits the second ball, which then steals its kinetic energy, allowing it to swing around. Once you get KaBlaster going, you won't want to put it down! This unique yo-yo puts the "fun" in fundamental physics. Available in Blue and Yellow or Purple and Green.

AstroBlaster Collision Accelerator

The toy modeled after the dynamics of an exploding Super Nova! Simply hold the ASTRO-BLASTER in front of you, drop on a flat surface and watch as only the top ball "blasts off" into the air-UP TO 5 TIMES THE HEIGHT DROPPED! The famous astrophysicist, Dr. Stirling Colgate, created the ASTRO-BLASTER to demonstrate the awesome kinetic power of a super-nova. Each ASTRO-BLASTER comes with a story explaining how this toy and a super-nova are related. Each ASTRO-BLASTER also comes with two extra balls-because this much fun can't be contained indoors!

Levitron-Omega

Some things just get better and better. Enter the latest version of the Levitron, hailed as "the best new science toy in a generation" by the American Association of Physics Teachers, and loved the world over by experts and amateurs alike. Unique, fun, and sophisticated, the Levitron is the perfect gift for the person who has everything - or for anyone else, for that matter! Just spin the top and watch it float, spinning and surfing on magnetic waves. Pass your hand above, beneath, and around the top without affecting its performance, without affecting its marvelous movements in midair. Supported solely by the repelling magnetic force produced by permanent magnets, the Levitron requires absolutely no batteries, and can be used anytime, anywhere. And this updated, state-of-the-art model floats TWICE as high as its predecessors, for twice the excitement. Tell your friends that there is a century-old scientific theorem that states that this sort of thing is impossible - but the Levitron tells quite a different story, levitating like a genii on a magic carpet right before your eyes.
