  • 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...

  • Constant Speed Vehicle
    Constant Speed Vehicle

    Some sort of crawler has long been a favorite for introducing the ideas of velocity and acceleration. This product has a three position switch so that it can be powered in either direction, a stable platform for carrying objects, a hook for towing and blunt ends for pushing. A spacer is included to take the place of one battery for half speed operation. Requires 2 C-size batteries.

  • Collision Balls
    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.
