Newton Cradle, Balance Ball, Office Desktop Home Decoration Gift, Educational Kits

Material: Frame: plastic (coating film to be silver) Base: plastic (painted to be dark red or black) Ball: steel (5 balls, could be 7 balls, we accept customized) Usage: 1) 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! 2) 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! 3) You can also try: Pull one ball of each side with same height. Pull one ball of each side with different height.
