The Euthanasia Coaster is an art concept for a steel roller coaster designed to kill its passengers. In 2010, it was designed and made into a scale model by Julijonas Urbonas, a PhD candidate at the Royal College of Art in London. Urbonas, who has worked at an amusement park, stated that the goal of his concept roller coaster is to take lives "with elegance and euphoria"
