Wim Delvoye, a Belgian artist, had put in eight long years to build the Cloaca, also know as the “poo machine”, and was created with the help of experts in gastroenterology and plumbing. Delvoye set up the intricate machinery at the Museum of Contemporary Art in Antwerp, Belgium in 2000. The machine imitates the human digestive system through a series of vacuums that contain human digestive juices and enzymes. Food is dropped into a funnel and in a process that emulates the human teeth is reduced into very small pieces. It then passes through several vacuums comparable to how food is processed in the human digestive tract. The resulting ‘product’ is then vacuum-packed and sold to guests. Delvoye is known for artworks and projects that are mostly inventive yet shocking and repulsive. If you find this interesting, you will find plenty more on his website.
