The Coca-Cola Friendship Machine: viral vending done right!

To celebrate the International Day of Friendship, Coca-Cola planted special vending machines that sold 2 Coke bottles for the price of one. Only one catch: standing at over 3 meters tall, you’d need help from a buddy to reach the slot; afterwards you could share the drinks. And isn’t that what friendship is all about? :)

Meanwhile, arch enemy PepsiCo responded with a similar idea, but their PepsiCo Social Vending was a bit more complicated.
