Coca Cola invites college students to experience the happiness factory via the aptly titled "Happiness Machine".
We've seen the human vending machine idea executed a few times (faves include The Kit-Kat machine) so although it's not totally original it is fun, heart-warming and does what any brand experience should d0 - creates a buzz and gets people talking.
Go to buy a Coke from your nearby machine and you might end up with ten bottles, or a pizza, or a rubber chicken. And isn't surprise one of lifes best loved treats?!
