Ok, so I'm microwaving some popcorn a little bit ago... Standing there watching it spin around and around must have put me in a hypnotic state as I began to ponder one of life's great mysteries. "Hmmmm, I wonder why I have to put the bag in there with a specific side facing up. Popcorn kernals are round aren't they? It shouldn't matter!" Would somebody please bestow their wisdom upon this poor soul?
