Go smart-water / keep on rolling SmartWater is a liquid containing a unique code that can be traced back to the person who sprays it. It is invisible to the naked eye but glows under UV light.

Some streets in neighbourhoods across the country display SmartWater signs on lamp posts and other fixtures to deter would-be turd-burglars.
