• * Newton's Cradle is a timeless, classic desktop science "toy" that is the perfect blend of science and art.
• *This is a shiny, nicely balanced, high-performance example of the classic Newton's Cradle - a ball on one end of a row of balls suspended, barely touching balls swings into the others, and the ball at the opposite end reacts to the collision.
• *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.
