Rio de Janeiro has beautiful beaches, but they are always dirty because of people's bad habits. How can we get people to throw garbage always in the trash?
Approach
A shower with a built-in trash that detects the trash thrown and automatically releases water. Now every beer can, ice cream stick and all garbage you find in the sand will help you refresh as long as you throw them in the trash.
Results
A shower that cleans the people('s habits) and the beach.
