TOPS & GYROSCOPES

Showing 1 - 9 of 10 Incredible Things
TEDCO® CLASSIC METAL GYROSCOPE
Gyroscope
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.

MAGNETIC LEVITATION, SPINNING DESK TOY
Perpetual Motion
Spin this spindle and watch it turn in perpetuity!!  Well, for a long time anyway.  Inside the 5-1/2" long colored plastic spindle are magnets which are repelled by magnets in the 5" x 3" black plastic base.  The variously colored spindle floats in the air above the base thus virtually free of normal friction. Nifty desk toy named "Revolution".

LIGHT-UP GYROSCOPE
Gyro-Light
A gyroscope with added entertainment value, and no old-fashioned string to pull. Get it up to speed with the geared pull-strip, and a spinning red LED automatically lights up. The 2-3/4" tall x 2" dia gyro is metal and plastic, with a small plastic stunt stand, and will continue to balance intriguingly, even If you somehow manage to wear out the LED's non-replaceable batteries. For ages 8 and up.

CRYSTAL ANIMATOR WITH 18 STRIPS
Paper Praxinoscope
The praxinoscope was the successor to the zoetrope, and both precursed (darn!) motion pictures. This praxinoscope, marketed as the Crystal Animator", can be assembled in 10 minutes. The finished scope is 4" dia x approx 2-1/2" tall with a 10" long spinner/handle. Spin it and watch the horse appear to gallop in the mirrored core. Comes with (18) pre-printed strips--including the horse, people, pigs and many more--but you can create your own, which is twice the fun, on the reverse sides.

RATTLEBACKS
Newtonian Fun
Rattlebacks are plastic semi-elliptical shapes, 3-7/8" long, that illustrate Newton's laws of motion, while mystifying kids. Set them down (the rattlebacks, not the kids) and their offset center of gravity makes them spin. Spin them in one direction and they stop and reverse themselves. You get a package of (10) in blue, along with a lesson plan and suggested activities.

MAGNETIC FLASHING GYROSCOPE
Flashing Gyroscope On A Stick
At least three times as much fun as it ought to be, this magnetic gyroscope is festooned with multicolored LEDs that flash while it spins around a hand-held set of 2-1/2" dia wheelie tracks. Spins as long as you keep giving it a little wiggle, and you can't beat that. Includes (3) button-cell batteries for the flashers.

3" DIFFRACTION GRATING PATTERN TOPS
These Are Tops In Our Book
These are not only tops in our book, but there are a dozen of them. Plastic tops, approx 3" dia, with assorted diffraction grating patterns on top. Discs with very short axes, they cling close to the surface of whatever they're spinning on, which is cool. Safety-tested to be free of lead and other nasty stuff.
