## Description

History of Newton’s Cradle:Newton's cradle (also known as Newton's balls or Executive Ball Clicker), named after English 17th century scientist Isaac Newton, 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; a force is transmitted through the stationary spheres and pushes the last sphere upward. Newton's Laws of Motion: "For every action there is an equal and opposite re-action."Fine argument of Newton's law of motion and the starting point of physics. Inspired us to better understand the concept of conservation of momentum. Demonstrates Conservation of mechanical energy.Newton Cradle will never be outdated. It’s great for physical teachers, students, office workers, kids, men and women at all ages.

Review: A little bit cheap looking - The product looked and felt a bit cheap compared to other similar ones that I've seen. It was OK and as advertised however, I had a little higher expectations.
Review: Absolute garbage - Came so tangled I could barely get it apart & in the process of trying 2 of the balls came untied & were impossible to tie back together. Unfortunately the gas it would cost to drive 40 miles to a ups store is more expensive than the item was so in the trash or goes. Very disappointed customer.

### ⭐ Absolute garbage
*by L***E on July 15, 2023*

Came so tangled I could barely get it apart & in the process of trying 2 of the balls came untied & were impossible to tie back together. Unfortunately the gas it would cost to drive 40 miles to a ups store is more expensive than the item was so in the trash or goes. Very disappointed customer.

### ⭐⭐⭐⭐⭐ Good teaching aid
*by J***N on March 5, 2022*

I use this in my high school science class to demonstrate Newton's principle of force and reaction. The students were completely intrigued with the cradle. It was much more fun to use this as an object lesson than to just try to explain the principle verbally in class.
