Newton’s cradle is a device that demonstrates conservation of momentum and energy via a series of swinging spheres. The device is also known as Newton’s balls or “Executive Ball Clicker”.
Japanese art student at Musashino Art University, Yasutoki Kariya, created the installation Asobi, a wonderful lightbulb version of Newton’s Cradle, the physics toy also known as the “Executive Ball Clicker.” Eleven computer programmed lights are used in this visualization of kinetic energy and it has been coined ‘Edison’s Cradle’. Notice that the glass bulbs do not actually touch, preventing them from breaking. Asobi is currently a nominee for the Mitsubishi Chemical Junior Designer Award 2012.
