The water that you use from the world's water cycle is your private water part. The installation PRIVATE WATER PART celebrates precisely that part before you use it to, for instance, flush the toilet. The toilet's cistern is moved into the exhibition space, it is filled with water from the installation. The water is pumped from the red barrel into a small, 4 mm, space between the glass. The installation fills up and the water circulates between the double glass... until a PRIVATE WATER PART is used through the hole in the wall.
