The idea: Take a sign which says “Take away for free”, place it in the middle of a pedestrian area in the city center and place a couple of hundred non-deposit containers around the sign (small PET bottles and cans). The next step is to do the same with deposit carrying containers (=/> 1L PET) and the difference in behavior you see by the people passing by the two different piles of bottles is quite interesting, but I am certain you will know what happens.
