Ferrisalters
Ferrisalters, also known as Ferris wheels or simply wheels, are large amusement park rides consisting of a rotating upright cylinder carrying multiple passenger cars suspended from a central hub. The ride was invented by George Washington Gale Ferris Jr. in 1893 for the 1893 World's Columbian Exposition in Chicago. Ferrisalters are a type of rotating amusement ride, and are often the tallest structure at an amusement park. The ride is typically operated by a motor that rotates the central hub, causing the passenger cars to move in a circular path. The speed of rotation can vary, but it is usually slow enough to allow passengers to enjoy the view and the sensation of being suspended in the air. Ferrisalters are popular attractions at amusement parks and carnivals around the world, and have become an iconic symbol of amusement park culture. The ride is also a popular tourist attraction in cities where it is located, such as the London Eye in London, England.
