Rattleback (Celtic Stone).
The Rattleback is a long and thin half elliptical shape formed in plastic so that it has a slightly offset center of gravity. Also known as the Celtic stone, or wobble stone it is a fascinating object. You spin it in one direction, it slows down, wobbles, and then starts spinning in the opposite direction! This spin-reversal motion seems, at first sight, to violate the angular-momentum conservation law of physics. Moreover, for most...

Trajectory Apparatus
This rugged, compact device allows students to clearly visualize and quantify projectile motion. A steel ball is launched repeatedly from the same place on a ramp and strikes a recording paper on a target plate that is moved horizontally each time.

Collision Balls
This long form collection of 5 balls, each in adjustable two-line suspension, is one way of showing that both momentum and kinetic energy are conserved when some number of balls are swung back and released. The same number of balls swings out at the opposite side following the collision.Requires ring stand.

Adding Momenta
Twin hammers are mounted at right angles so each imparts a component of momentum to the croquet ball. The included reinforcement rings, on the user supplied paper, allow the precise positioning of the ball. The mounting clamp is included but the lab stand is not.
