Product Description

Law of motion in action

This product follows Sir Isaac Newton’s third law of motion. You pull up one ball and release it, you will see one ball move from that reaction. If you pull two balls and release them, then two balls will react.

“For every action, there is an equal and opposite reaction.”

-Isaac Newton
