Newton's Cradle, also called Balnce Balls, is a great desk and classroom science toy. This educational toy demonstrates the conservation of momentum and energy. Newton's first law of inertia - an object at rest tends to stay at rest and an object in motion tends to stay in motion unless acted on by an external force. Newton's second law - Force = mass X acceleration. Newton's third law - For every action there is an opposite and equal reaction.

Son used it once and it got so tangled up we had to throw it away. Uses a very thin fishing line. I even spent the extra money thinking it was a nicer one but now not so sure.
