BesnanLy Newton's cradle is a device that demonstrates conservation of momentum and energy using a series of swinging spheres.
When one sphere at the end is lifted and released, it strikes the stationary spheres, transmitting a force through the stationary spheres that pushes the last sphere upward.
The last sphere swings back and strikes the still nearly stationary spheres, repeating the effect in the opposite direction.
Our newtons cradle is made with a new technology that makes the balls in perfect alignment so you will never have to worry about the strings becoming tangled.
The beautiful colors and the fact that the balls move smoothly for an average time of 20 seconds make science more fun
Learning is more fun. This cradle is a perfect way for kids to learn about conservation of momentum and energy. They are great for psychology, science and physics classrooms and are also great for kids with ADHD or autism. That makes a great present for decorating an office. It is an effective way to relieve stress and frustration for children and office people.
