A childhood belief about drinks

Up until I was about 6 or 7, I used to think that, instead of entering the prize codes that I would find on my soda bottle caps on the internet, you were supposed to say the code out loud, and the prize would just apper in your hands. I never tried my theory, though, because I thought my parents would be mad, since I thought the prizes would cost money, and the money would dissapear.
