Peter Lustig wants to know exactly: With his special furniture, a desk with extra accessories, he sits in the middle of a stream bed. Water in front, water behind, water all around. Peter wants to get to know what everyone thoughtlessly consumes and uses every day. What could be more obvious than to take a look around out in nature, where the water comes from? And once you're sitting in the middle of the stream, you discover what all lives here and how easily a stream can be thrown out of balance. And because no one likes to drink the dirty water from exhausted streams anymore, Peter thinks about how such a poor body of water, constricted by the concrete corset and polluted by sewage, can be turned back into a beautiful, clear forest stream, from whose water Peter would like to make himself a coffee - on his desk with accessories.
