Invisible Vending Machines Surprise Lovers on Valentine's Day

Not only do vending machines offer all kinds of products, including piping-hot burritos and crunchy salads, but they also come in all shapes and sizes. For Valentine’s Day this year however, Coca-Cola managed to create a truly original offering, in the form of an ‘invisible vending machine’ that only reveals itself to passing couples.
When the machine detects a passing couple, it lights up and asks them their names. After a short wait, complete with some visual entertainment, the couple are presented with a pair of cans complete with the names they just shouted out to the machine.
