Inter Milan and AC Milan are two intense rival football teams thanks to decades of competition within the same city. So Coca-Cola and agency McCann Worldgroup Milan decided to challenge Inter and Milan fans to see if they could share a little goodwill.

Coke installed vending machines on each side of Milan's San Siro stadium ahead of a derby match, equipped with cameras and screens. But the catch was that only Inter fans could give Milan fans a free soda, and vice versa.

Watch how the fans reacted to their rival team's fans in the video below:
