Kudos to this Fanta elevator experience from Brazil:
I love the expression of the guy (0.16) who automatically says 'hi' back and then is struck with the realization that there is no one in the elevator with him.
Unlike Brazilian elevator antics of the SOS Fauna campaign, which has a high risk of annoying someone, people seem genuinely happy to be participating in the Fanta elevator.
I want to be in the Fanta elevator! This is much better than the elevator I have to be in at work that will cut your arm off if you don't get in fast enough. The Fanta elevator becomes extremely awesome when the orange plastic balls fall from above and transforms the lift into a Fanta ball pit.
