It’s funny, but when I start to think about the laws of conservation of mass and energy, I get hungry and inevitably a little distracted. Maybe that’s why I got a B- in physics back in high school?
Well, my grades aside, it looks the folks at ThinkGeek had me in mind when they created this Newton’s Cradle Fridge Magnet. You can watch the magnet in action, think about physics and then get a sandwich. Then again, it might distract you long enough that you stay on your diet. It’s brilliant!
