That will teach em. 
Late night revellers and heavy drinkers may think nothing of relieving themselves in public.
But now walls are fighting back against the disgusting habit.
Walls in San Francisco have been coated with water-repellent paint so that desperate drinkers get a nasty surprise if they urinate on them.
Nine walls around the Mission and Soma districts have been treated with hydrophobic Ultra-Ever Dry paint, so that if someone wees on them, their urine sprays back over their legs and shoes, hopefully deterring them from urinating in public again.
The nanotechnology spray can be applied to almost any material.
It turns into a super hydrophobic shield when applied, so that breeze blocks can be made non-porous, walls hydrophobic and gloves completely dry even when submerged in water, for example.
