Why do cans of Diet Coke float, but cans of regular Coke sink?
Did you know if you put a can of regular coke in a pool of water, it will sink (naturally, right?) BUT if you put the same size can of Diet Coke in a pool of water it will float.
Crazy, right? Well, if anyone can tell me why I will shower you with discounts. Here's the trick though - you have to be able to explain it.
