It was invented by Theophilus Van Kannel, who also invented the revolving door.[3] It consisted of a large oval course with a flexible metal floor. There were hidden reciprocating levers that produced a wave-like motion. The floor itself did not move but the moving wave propelled small scooter-style cars with two seats, which could be steered by the riders.
It was installed at other amusement park locations, including Blackpool in England,[4] London’s Imperial National Exhibition in 1909, Euclid Beach Park in Cleveland, Paragon Park in Massachusetts, Saturno Park in Barcelona, Rockaway Beach, and Palisades Park in New Jersey.
It is about the biggest fair in England. The whole of St Giles' … is thick with freak shows, roundabouts, cake-walks, the whip, and the witching waves.[5]
