How to trick Rival Football Fans to have fun together

I like this stunt by Coke, it was performed at the San Siro stadium in Milan, home of an ongoing derby that divides the city, the idea comprised 2 vending machines, each one was placed on the one of stadium sides, these machines allows anyone to share a Coke can with a fan of the rival team, hit the share button and the can will sent to the other side, and to ensure the excitement, these machines were fitted with a live camera feed, it’s really awesome!
