The residents of the St. Pauli neighborhood of Hamburg, Germany were tired of tourists and drunken revelers using their home as their toilets, so they decided to fight back — with science!
Bored Panda reports that a local organization covered many of the public walls throughout the area with a super-hydrophobic substance. If a careless visitor decides to relieve himself on one of these walls, they shall reap what they sow.
They’ll be splashed with their own pee.
Some of the walls coated with the substance are labelled to ward people off. Others aren’t.
The creators of this ingenious scheme created a delightful campaign video, which you can watch above, that warns careless public urinators, “it’s peeback time.”
