Custom mini cans feature Hulk, Ant-Man, Falcon, Captain America,
Black Widow, and Iron Man.
There were six easter eggs in the commercial––including phone numbers, a Snapcode, URLs, and the coordinates of the lab––which led to thousands of limited edition Cokes and prizes. Fans found them all in a week.

Best of all, since Hulk and Ant-Man had never met onscreen before this commercial, fans declared this as "canon" and so our story becomes immortal in the Marvel Cinematic Universe.
