Snap on the ratchet top, crank it up and push the button, and this 3-3/8" tall top spins like a demented dervish. The bottom is a big spring, so it'll bounce, too. The auto part is the light inside the top of the top, which lights up only when it's spinning. Includes (2) button cell batteries. We'll select a lovely, top-like color for you.

38102 AUTO-TOP |
2" flywheel in well made metal frame. The trick is the same as it has been for 100 years. Wind the string through the spindle, pull it firmly to set the flywheel spinning, and perform effortless balancing magic on pencil tips, string tightropes, and the like. We tend to forget that bicycles and aircraft navigation both rely heavily on gyroscopic principles. It's never too early to tell the kids. Besides, it's fun.

93368 ET'S TOP |
The future of train travel, and the essence of magnetism, is demonstrated in this Omega" levitating top from Levitron®. No science teacher should be without it. A little hard to start, like a '62 Falcon we once owned, but much, much more satisfying, and staggeringly educational once you get it going. The phrase "fiendishly clever" has been bandied about the office on this one. The magnetic top floats over a 4-1/2" plate with an opposite charge. On a black plastic tripod base, it comes with (10) counterweights of various materials, an instruction pamphlet and tips on making it work. Set the weight, level the base, keep a steady hand, and it will spin-suspended in air-for extended periods.
