| Who knew the conservation of momentum and kinetic energy could be this fun? Sir isaac, of course. This newtons cradle with mirror desktop display piece has become a must have for office décor. Swing one steel marble back, let it go and watch as kinetic energy causes the one on the opposite side to swing the same distance. If you're feeling saucy one day, try swinging two or three at once just don't pass out from the excitement. This desktop display model is a version of newton's cradle, a device that demonstrates conservation of momentum and energy via a series of identically sized swinging spheres. When one ball on the end is lifted and released, the resulting force travels through the line and pushes the last ball upward. Because it uses newton's laws, it was named after sir ISAAC newton, english physicist, mathematician and astronomer, but was actually "invented" (brought into commercial application) in 1967 by english actor simon prebble.
1. ENTERTAINING: These little steel balls will keep you entertained all day. The back and forth motion is a soothing experience you'll enjoy day after day while also learning about the conservation of momentum and energy. Newton's Cradles never get old, great for any science and physics classroom and are also great for kids with ADHD or autism.
2. GREAT DECOR PIECE: Desktop display version of Newton's cradle performing based on Newton's Law. Made with technology that gives the balls perfect alignment so you will never have to worry about the strings becoming tangled and looking messed up.
3. LEARNING TOOL: Newton's Cradles demonstrate Newton's laws of motion, specifically that "for every action there is an equal opposite reaction." This helps people better understand the concepts of conservation and momentum. Perfect for teachers teaching students the laws of physics. Perfect for physics teachers, students in school, office workers, kids and men and women all ages
4. SIZE: L6.2" x W3.5" x H4.5"
