Most festival guest have at some point seen used condoms lying on the ground. It is not the kind of waste you are collecting yourself, so a group of students has developed a concept that makes it easier for the owner to throw out his used condom properly.
The group handed out 500 free condoms at the festival, where a small bag is packed around. This bag is used to store the used condom until you have the opportunity to throw it out. No waste, no sticky fingers, no angry teammates.
