A riveting demonstration of conservation of energy, conservation of momentum, and projectile motion, the Loop the Loop looks like the track of a rollercoaster. The curved metal track allows you to drop a steel ball from the top and watch the results. Depending on the height at which it is dropped the ball will roll completely around the interior of the track or will drop to the ground. A circular scale is attached to the device for measuring the angle at which the ball drops. Includes two steel balls and instructions. Size: 110cm L.
WARNING: CHOKING HAZARD - Small parts. Not for children under 3 yrs.
