Large Newton's Cradle
Newton's cradle, named after Sir Isaac Newton, is a device that demonstrates conservation of momentum and energy via a series of swinging spheres. When one on the end is lifted and released, the resulting force travels through the line and pushes the last one upward. The device is also known as Newton's balls or Executive Ball Clicker. Pull up 1 ball of the Newton's Cradle, release it, and on impact, only 1 ball moves from that reaction. Pull up 2 balls of the Newton's Cradle, release and 2 balls will react! This simple yet unexpected result from the Newton's Cradle shows that every action has an equal and opposite reaction. The contact of the outer ball with the inner balls of Newton's Cradle has the visually startling effect of moving all the energy through the stationary balls, because only the outer balls move in an equal reaction to each other. Thus, Newton's Cradle demonstrates that an object in motion continues in motion with the same speed and direction unless acted upon by an unbalanced force. That's a little fact for you to crack out one time, we'll give you that for nothing. Newton's Cradle delivers a daily dose of unprecedented genius into your life, who knows, maybe the sparkling intelligence and inspiration will rub off on you? !
