No longer will you need to keep your physics balls at your boring desk. Now you can play with your balls while you cook, while you eat, or while just passing by with the magnetic Newton's cradle physics balls. Simply stick it right to your refrigerator, your filing cabinet, your locker, or really anything that's metal, and start bouncing your balls back and forth immediately. With each open of your refrigerator door, you will begin to hear the click clack sounds as your balls get jostled back and forth while searching for a snack to eat. Take all those terrible and cheesy Christmas cards you got from your family members last year and throw them in the trash to make room for these majestic swinging balls that will make you look smarter as you explain to guests how it demonstrates the laws of conservation of mass and energy.
