Your school is having an activity on making money out of trash. Your best friend will be representing your section in the pageant. One of the criteria to win is that you should have trash convertible to cash. The candidate with the biggest amount of money will be declared the winner. The proceeds will go to the purchase of garage bins for the whole school. So you readily agreed to help. But you have to find some big catch when it comes to trash. The heavier the trash is the bigger is its value. So you decided to go to abandoned factories and search for scraps of metal.
