Coca-Cola Israel and Tel-Aviv based creative agency Gefen Team have designed a Coke bottle that takes a selfie photo of the drinker.  The novel device easily attaches to a half-liter Coke bottle. It then senses the exact moment the bottle reaches a 70-degree tilt, the ideal angle for taking selfies, before snapping a photo.
