The muddy-hands survey

An unused plot of land in Yelahanka,Bangalore, which has degraded to become a garbage dump is the site for this work. An object (a bag of chocolates, a mobile phone, a pair of jeans) and a weighing machine are kept besides the plot. A board with instructional information is already put up there. Anyone who can collect garbage from the plot which weighs as much as the object placed on the weighing machine gets to keep the object. If a particular object doesn’t excite people enough to get their hands dirty for it, it will be replaced by another one. It will work as a survey to figure out what people are prepared to get their hands muddy for. What is an incentive enough?
