Named after Sir Isaac Newton and inspired by a version of his First Law, Newtons-Cradle has appeared in many movies, including âSuperman IIâ. As soon as one of the outer balls is lifted, it hits the other balls. Not only can one ball be lifted but many at once, and a greater amount of force is applied against the balls that are static. Although it is used by scientists to study momentum and energy, it is also a fun toy. Small Newtons-Cradles are available for people to put on their desk. When wanting to take a break from working, an adult can play with their toy.
Not only is this toy designed for adults, it is also an educational toy for children. Fun to play with, it can also be purchased for children who are studying science at school. As it can be dismantled and assembled relatively easy, a child could even take it into their class. This toy is also safe for young children. As the balls cannot be removed unless the individual strings are cut with scissors.
