This is a simple tutorial on how to read the code underneath a bottle cap without actually opening the bottle. We use the LED on an iPhone to create a reflection onto the surface of the soda, which you can then easily read. You can use an App on your phone to automatically flip the image since it will be backwards, or you can just read the code backwards. This is very helpful for the "Every 2 Minutes" Promotion so you can read the codes without having your soda go flat.
