Make Your Own Newton's Cradle!
Now you can learn about the law of conservation of momentum by building your own Newton’s Cradle. Plastic rings are included for adjusting the positions of the marbles. Pull one ball away and let it fall. If you line them up correctly, it will strike the first stationary ball in the series and come to a stop. The ball on the other side gets most of the energy from the first ball, flies outward, then falls back to repeat the process.
Includes plywood rails, string and marbles. No tools required! Assembled measurements: 2.4" x 4.7" x 4.7''
