Newton's Cradle is a timeless, classic desktop science "toy" that is the
perfect blend of science and art. Lift one steel ball and allow to fall back
at one end, the ball at the opposite end will swing out the same distance.
Stylish chrome and black color scheme. Fascinating to watch. Also known as
"Balance Balls", "Newton's Pendulum" and "Newton's Balls", this executive
office toy demonstrates the law of conservation of momentum. Using Newton's
third law has never been this much fun! What happens when you swing two? Or
three? Newton's Cradle was invented in 1967 by English actor Simon Prebble and
named in honor of scientist and mathematician Isaac Newton because it employs
Newton's Laws.

• 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 bal l. 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") in mahogany/cherry wood colorwith metal balls.
