A Ferris wheel is a large, rotating amusement ride consisting of a vertical rotating wheel with passenger cabins attached along its circumference. It was invented by George Washington Gale Ferris Jr. in 1893 for the World's Columbian Exposition in Chicago. Ferris wheels are often found at amusement parks, fairs, and tourist attractions, providing riders with a panoramic view of the surrounding area. Typically, a Ferris wheel operates at a slow speed, allowing passengers to board and disembark safely. The height of these structures can vary significantly, with some reaching over 200 feet tall. They are popular for their ability to offer a unique perspective and a sense of thrill while being suitable for all ages.
