Invented by Amariah Lake of New Jersey in 1893, the haunted swing was a Victorian era amusement ride. Participants entered a room and took a seat on the swing provided. When the ride got underway, the attendant gave the swing a push. As it moved, it appeared to rotate, creating an illusion that the people on the ride were upside down. In truth, the swing stayed in the same position, and it was the small room surrounding them that rotated.
