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". As for practical applications of his design, Urbonas mentioned "euthanasia or execution". John Allen, who served as president of the Philadelphia Toboggan Company, inspired Urbonas with his description of the ideal roller coaster as one that "sends out 24 people and they all come back dead". As a hypothetical means of euthanasia, the design led to concern from anti-euthanasia associations such as Care Not Killing.
