Wateraid chases Londoners with this remote controlled poo to demonstrate the plight of the 2.6 billion people globally who don't have access to a toilet. The victims of WaterAid's poo can escape -- but billions of people across the world can't. Living without proper toilets means people have to go wherever they can. This causes deadly diarrhoea, which kills 4,000 children a day. Help make it stop. Sign our petition at http://digtoilets.org/poo/
