1. Small Rattlebacks / Celts Classroom Set of 24, Prizes, Physics Demonstration Item
Feature
Small, easy to use size!Set of 24 Rattlebacks
Description
Rattlebacks, also called Celts, are an intriguing piece of wizardry or science, depending on your audience. The shape of the piece allows it to be rotated or spun. in a few seconds it will rattle, stop, then spin in the opposite direction. As a magic piece, you can pretend to cause the action with your mind power. As a scientific diversion, why does it work? These are small rattlebacks that work perfectly, but are at a size (and price) that everyone in your class or gathering can have one! (Penny is for size comparison only - not included.) Buy now and start spinning!2. Pack of (10) Rattleback Physics Curiosities-- Challenge the Law of Conservation of Angular Momentum!

Feature
Assorted colorsIncludes Teacher's Guide
Each one measures approximately 98mm or just under 4 inches.
Pack of 10
Description
The Rattleback is a long and thin half-elliptical shape formed in plastic so that it has a slightly offset center of gravity. This offset gravity causes the Rattle back to spin in directional rotation of choice, usually counterclockwise. If you attempt to spin the Rattleback in the clockwise direction, strong preference will cause the Rattleback to "rattle" back and forth after few rotations, stopping and then reversing the rotation back to the preferred counterclockwise direction. The directional preference is so strong that if the Rattleback is at a standstill and you push down on one end it will begin turning. Color may vary. Comes with Teacher's Guide.6.
