St. Pauli is one of Hamburg’s top entertainment destinations, attracting as many as 20 million visitors a year with its popular nightclubs and legal prostitution. However the steady stream of visitors has many residents and merchants angry as the visitors often relieve themselves against walls which leaves the whole place smelling like a latrine.
So to combat this, St. Pauli merchants association is fighting back by coating the most frequented walls with Ultra Ever Dry, a hyper-hydrophobic nano paint originally developed by Nissan. Now when urine hits this paint, it splashes back, soaking the offender’s pants and shoes with his own urine.
UPDATE: Pee-repellant walls commissioned by San Franciso Public Works
