Newton’s Cradle Perpetual Motion Machine is rated 1.0 out of 5 by 1.
Rated 1 out of 5 by from Poor Quality The base and frame are solid but the strings for this unit are not. The string appears to be fishing line going from the ball to the frame and its just tied to the frame with awkward knots sticking out. Had this piece for a week and movied it from one side of my desk to the other and one of the stings broke away from the frame. Its deffinatly not worth the price you pay.
