Get into the swing of things

If we had one wish, we'd wish for a million more wishes. And with one of those million wishes, we'd wish our refrigerator could do more than just keep things chillin' - more than even those fancy-pants ones that have a water and ice dispenser. We'd want our fridge to do physics.

And now it can. With the Newton's Cradle Fridge Magnet your refrigerator can demonstrate the laws of conservation of mass and energy each time you open and close the door. CLACK-CLACK-CLACK. Need a beer? CLACK-CLACK-CLACK. Standing in the kitchen waiting for a pot to boil while trying not to watch it? Watch this instead! CLACK-CLACK-CLACK. Magnetic poetry kits are so last decade as a way to kill time in the kitchen while you're waiting in line for the microwave. (Except for the ones we make, naturally.) Next time, do physics to it. You'll be glad you did.
