This unusual project called ‘Tap Project’ was initiated by UNICEF. This vending machine was installed in Manhattan and people had choice between bottles that “contained” Malaria, Cholera, Typhoid or Dengue. And the bottled water was really dirty. All this to raise awareness of water conservation and to remind that not every one in the world has this possibility to drink crystal clear water, what we take for granted very often. No one drank this dirty water, of course, but many people donated.
