Newtons Cradle is named after Sir Isaac Newton himself, an invention which he employed to demonstrate a scientific discovery. Pull up 1 ball of the Newtons Cradle, release it, and on impact, only 1 ball moves from that reaction. Pull up 2 balls of the Newtons Cradle, release them and then 2 balls will react! The simple yet unexpected result from the Newtons Cradle shows that every action has an equal and opposite reaction.
