Washington: Sick of the foul stench on the walls due to some people's disgusted habit of peeing on the walls? Worry not as a now the walls will pee back at them.
Folks from St Pauli, the party quarter of Hamburg, Germany, have come up with an out of the box solution, which makes the wall reflect the pee, and could make the people think twice before relieving themselves on the walls, Discovery News reported.
Walls that take the most abuse were sprayed with Ultra Ever Dry, a hydrophobic coating, which makes any liquids directed onto the surface repel and splash back. Warning signs were posted.
After that, men who peed against the coated got sprayed back.
Julia Staron, a spokesperson for the project said in a Youtube video that "not every wall has a warning sign, so consider yourself warned, street pissers."
