See the laws of Physics in motion with Sir Isaac Newton's classic model. If you pull up one ball and release, you will see only one ball move from that reaction. If you pull up two balls, two balls will react. Try it and see for yourself.

Swing one ball back, let it go, and watch the energy transfer through to the ball on the opposite end as it swings to almost the same height. But the fun doesn’t stop there; the balls continue to swing until energy loss due to air resistance and transfer to sound slows the momentum, allowing you to observe the principles of conservative motion right in front of you.
