Says it all in the headline. Hang house and car keys separately, or just pinch the middle and it's a ball-bearing spinner ready to relieve your fidgetous anxiety. Try to do both at the same time, however, and you'll find a new level of frustration unless your thumb and index finger are six inches long. (Surplus!) We'll send you one in a lucky shade of bright green. And just to be clear, you can’t use these for mountain climbing—only for keys and amusement.

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".

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 assorted colors, along with a lesson plan and suggested activities.

Admit it, we all still love to spin. These fidget spinners have a radius of about 1-1/2”, and a great feel. Better than that, they’re branded, which means you’ll get one with an official Looney Tunes or Justice League design on it. Yeah, we’re talking Bugs Bunny, Tweety Bird, Tasmanian Devil and Batman—every last one of them a great spinner. We'll reach into our grab bag and pull one out. ! WARNING: CHOKING HAZARD–Small Parts. Not for children under 3 yrs.

A tiny touch of whimsy from your local scientific and surplus monger. You get a trio of 1-3/4" dia x approx 2-5/8" tall plastic tops in assorted colors, with the American Science & Surplus logo on the disc. The tops of the tops have a vaguely Constantinopolitan shape, and are a different color from the bottom. Just one more dazzling detail from Jarvis.
