Bottle Bank Arcade The FunTheory.com

The FunTheory.com conducts an experiment in order to get people to recycle their bottles by making it a fun activity. The experimenter sets up a bottle bank with flashing lights and a display, giving the player points for their bottles.

The flashy bottle bank receives bottles from 100 people, while a nearby bottle bank is used only twice. Considering that one of the hardest parts about changing our behavior is changing our attitude about something, would this be an effective way to get all people to recycle? What other games do you think would make green activities entertaining?
