NEWTON'S CRADLE Balancing Ball Newton's Cradles are great for home of the office desk!
This 7" tall hypnotizing toy will keep you amused for hours. Newton's Cradle of an odd number of identical steel balls each suspended by a bifilar suspension from a sturdy frame.
The balls are aligned along a horizontal line, just touching. When the ball on one end is pulled aside and allowed to swing as a pendulum,it hits the next ball.
The outcome is fascinating, the one ball on the far end is knocked away from the others with the same speed as the first ball had initially and all of the other balls remain nearly at rest !.
If you pull back two balls and let them strike the others,two balls are knocked from the other end, and all the other balls remain nearly at rest.
Great for stress relief and makes a wonderful gift!
Wooden base (7"x4.5") with metal balls.
