The Euthanasia Coaster is a concept for a steel roller coaster designed to kill its passengers. In 2010 it was designed and made into a scale model by Julionas Urbonas, a PhD candidate at the Royal College of Art in London. His concept for the coaster was to take lives with, "elegance and euphoria." The seven loops, or inversion, put the body under such stress that it causes the brain to be starved of oxygen. A fun death, if rather macabre.
