Don't pee in public, now walls can throw it back

In a bid to teach drunken revellers a lesson, people in a night club locality in Hamburg have coated their walls with a special paint that bounces back urine on the urinator.The hydrophobic (waterrepellent) paint, if urinated upon, makes the urine bounce off the wall and back at the urinators' feet who relieve themselves in the public.
Walls in the St Pauli nightclub district have been painted with a super-hydrophobic coating and given accompanying signs, which read, `Do not pee here. We pee back!', media reports said. Residents of the St Pauli neighbourhood, sick of starting their day with the biting stench of urine, have begun coating their walls with the paint. The high-tech coating guarantees the urine bounces on to the urinator.
The special `superhyperhydrophobic' coating goes by the trade-name `Ultra-Ever-Dry' and was originally developed in 2012 by the US company Resource Energy Group. It can be used to coat cars and fabrics, but also wood and brick. The paint costs $446 a gallon (3.7 litres). About $700 is required to cover six square meters with urine-repelling paint.
