SAN FRANCISCO (AP) - The problem with public urination in San Francisco has become so bad that the city has painted nine walls with a repellant material that makes offenders' pee spray back at them.
Walls are coated with the clear liquid repellant material, which goes on much like paint. Any urine that hits the material sprays back on a person's shoes and pants.
Mohammed Nuru is director of the city's public works department and calls himself Mr. Clean. He got the idea from St. Pauli quarter in Hamburg, Germany, where walls are painted with the clear material to discourage late-night beer drinkers from urinating in alleyways.
It's San Francisco's latest effort in its battle against public urination. The city also has solar-powered rolling toilets in one neighborhood and attendants manning public toilets to encourage people to use them.
