Steps of Newtons Cradle Assembly : First, gently open the packaging of the office gadgets. Second, carefully separate the steel support frame.Please be patient and careful during the installation process, as excessive force will cause entanglement!

Fine argument of Newton's law of motion and the starting point of physics.

Silver Ball Made of high quality Stainless Steel that will last for long.

The balls continue in perpetual motion FOR ONLY 15-25 SECONDS due to the resistance of the air and friction.

We can not create a vacuum environment, so the balls will have some space when it is working, but it won't influence the effect of playing.

Funny and useful for those kids who want to learn more about magnet and physics: Just lift up one or more outer balls and let them loose - As soon as they meet the other ones, the same amount of balls on the other side will start swinging. This way, Newton’s cradle combines physics and art for some interesting scientific insights. What is more, the balance pendulum is an ideal gift for young and old curious minds. An exquisite decoration that can be placed in house,school or office.Sleek desk toy for adults and children.
