Newton's Cradle Fridge Magnet

Newton's Cradle Fridge Magnet

Endless clever fridge magnets have been forged into existence, but besides sticking things to metal, they don't really do much else. The cool new Newton's Cradle Fridge Magnet changes everything. This unique fridge magnet not only holds pictures, memos, report cards, menus, and other assorted papers securely to the fridge or other metal objects, it also has a functional Newton's Cradle with tethered steel balls that clack away back and forth against each other to demonstrate the laws of conservation of mass and energy and also effectively relieve total boredom in the kitchen. It's also perfect for school lockers to inspire physics students, filing cabinets for something more interesting to do at the office, washing machines to help pass the time, or wherever there's a magnetic surface that needs more hypnotic clacking balls.
