Newton’s Cradle Fridge Magnet

Newtons Cradle Fridge Magnet

Much like your regular Newton’s Cradle that you put on your desk and waste time playing with, cept’ this one goes on your fridge. Every time you open your refrigerator you will be reminded of the laws of conservation of mass and energy from the sound we all know and love.. CLACK, CLACK, CLACK, CLACK.  **Warning: Your cat will probably try to attack this while it is clacking.
