The Pee Tree by Joa Herrenknecht is a conceptual product that allows people to do their business without going to the public restroom (because it’s far away and a bit scary?).
“Because on wildlife hunting-ground men ambitiously love to find an adequate tree for their short basic needs and because in our modern age they tend to substitute these through the corners of our cities, the thought ? to bring back the pee-trees ? is virtually obtruded.”
And no, there won’t be a yellow pond around the tree. The urine is directly flushed down to underground sewage canal.
