Public urination is a common problem in every major city around the world, particularly those that have popular party neighborhoods or red-light districts. Hamburg is one such city, with its St. Pauli neighborhood regularly victimized by late-night revelers looking to empty their bladders. To battle this problem, walls in the neighborhood are being covered in a hydrophobic paint that splashes urine back to perpetrators.
The walls are coated with Ultra-Ever Dry super-hydrophobic, oleophobic nano-coating paint. While some of the walls have signs warning people of the consequences of peeing on them, not all do, so if you're in St. Pauli and need to take a pee, think twice before aiming.
This creative anti-public urination venture is dubbed 'St. Pauli Pees Back' and is a funny and effective way to tackle a problem that's no laughing matter––especially for those who live in the neighborhood.
