The granddaddy of desk toys! Sir Isaac didn’t invent this gadget, but he did describe the laws of motion that bear his name, and that this demonstrates.
Gently swinging, softly clacking metal balls are soothing and inspiring! Our version has a shiny silver-colored cradle and balls that are suspended by clear threads.
The mini fits anywhere, even a crowded cubicle. The regular size looks great on a shelf or coffee table. For information on the physics of Newton’s Cradle see the tab below.
For a concise description of the physics of a Newton’s Cradle, see this explanation from the Physics Department of Brown University.
