Not only vegetable material, but also animal residual waste can perfectly serve as a raw material for design. Did you know that one gut of a cow can be up to 50 meters long? The Danish designer Kathrine Barbro Bendixen apparently does: she actually made a collection of lamps with "Inside Out". Each lamp consists of a hanging fixture and an LED tube surrounded by the meter-long cow intestine. In preparation, the casing was first turned inside out and covered with a thin layer of foil for firmness, after which air was blown in for the winding form. By the way, that air will gradually escape from the cow's gut, which means that the lamp can unfortunately not stay on the ceiling forever.
