Westminster Newton's Cradle - 5.5" Review

Westminster Newton's Cradle - 5.5" Feature

• One of the most classic of the "classic" education toys
• Excellent Executive Toy
• Start a kinetic chain reaction with one ball.
• Crazy physics fun for everyone!

The classic "desk toy".Using Newton's third law has never been this much fun! Swing one ball and one ball on opposite ends swings in response. What happens when you swing two?
