This is a model of a Newton's Cradle. It's a device that demonstrates the Law of Conservation of Momentum. Carefully lift one of the apples with the mouse and then let it go. You can pull as many as you want. (metal click clack balls, executive desk toy, science, energy, simulation)
Sometimes it glitches out, just click the flag to reset it. Push start first and then click apples :) Wow, thank you for all the stars and hearts! This is the most complicated project I ever made. :) Sometimes it glitches out, just click the flag to reset it.
