German Wall Will Pee Back on You If You Pee On It [VIDEO]
If this doesn't stop public urination, I don't know what will.
If you have been to a bar district anywhere you have seen it, guys peeing outside. One because they're probably drunk or the line is too long. Mostly it's the drunken factor not giving a crap because you really have to go. In Hamberg, Germany they have a real problem with public urination and they decided to get the walls to fight back for them.
They sprayed down the walls with this coating that repels all liquids. So if someone pees on the wall it will bounce off and go on them. I think if this were to happen to you once, you would never pee outside again.
