Be careful !!! in Hamburg (Germany), in the district of thirst, an anti-pee paint now covers the walls of a lively neighborhood. The people were tired of seeing the cliens bars urinating in the street. They found a solution: coat the walls regularly covered with an anti-pee hydrophobic paint. Result, return to the sender! The coating returns the urine stream directly on the shoes of the author. Only one problem, this painting is expensive: 500 dollars to cover about 6 square meters.
