“Euthanasia Coaster” is a hypothetic euthanasia machine in the form of a roller coaster, engineered to humanely – with elegance and euphoria – take the life of a human being. Riding the coaster’s track, the rider is subjected to a series of intensive motion elements that induce various unique experiences: from euphoria to thrill, and from tunnel vision to loss of consciousness, and, eventually, death.
