University of Stuttgart makes Urbach Tower from self-shaping wood

University of Stuttgart engineers have harnessed the natural shrinking process of wood as it loses moisture to create this world-first self-twisted tower in Germany.
The university's Institute for Computational Design and Construction (ICD) and Institute for Building Structures and Structural Design (ITKE) built the Urbach Tower in the Rems Valley for the Remstal Garden Show.The structure is made using a new, non-energy-intensive process that involves predicting how wood will shrink as it dries
