The installation entails a large scale physical diagram that shows the role our bodies play in the water cycle. At the entrance, visitors are invited to sit down on a toilet facing a water fountain, as if to drink while peeing. Their bodies close a physical loop between tubing that forms a circle around the installation - beginning at the toilet and ending at the water fountain. In between, the tubes pass through 2 functioning aquariums, a biochemical reaction mechanism, and a plant that is fertilized by the reaction's byproducts. The reaction illustrates the extraction from urine of nutrients that are harmful to aquatic ecosystems for use as a local fertilizer.
