San Francisco uses 'pee-proof' paint
Janitors everywhere are rejoicing. San Francisco city officials are implementing a new "pee-proof" paint around the city to combat the persistent problem of public urination. Public Works crews have painted 10 walls in the city with a special UV-coated, urine-repellent paint, according to CNN affiliate KPIX. Public Works Director Mohammed Nuru was inspired by a project in Hamburg, Germany, where walls in a night club district were coated with the liquid-repellent paint.
