There’s a reason San Francisco is considered the epicenter of tech. And, it’s not just because giants like Google and Facebook and every start-up under the sun call it home. No, it's for shining technological achievements like urine-resistant walls.
If you’ve spent any time in certain parts of S.F., there’s no masking the potent scent of the pee-covered alleys and streets. It has become such a big issue, in fact, that the Department of Public Works is looking to test a liquid-resistant paint to prevent people from openly relieving themselves in public.
The paint, dubbed Ultra-Ever Dry by Ultra Tech, is already proving to be helpful in Hamburg, Germany, where according to SF Gate, city officials use it to spray in the St. Pauli Red Light District. How does it work? Once the offender attempts to urinate on the surface, the liquid is repelled back onto his or her feet and legs — making for a really messy surprise.
Right now, the Department of Public Works is looking for specific areas in the city to test and is taking suggestions. (You can even email the department here if you feel compelled.) While a less aggressive solution might be adding more public restrooms, we admit this is a much more interesting option.
