The Ferris Wheel was invented in 1893 by George Washington Gale Ferris Jr. in Chicago. A Ferris wheel is an amusement ride consisting of a rotating upright wheel with multiple passenger seats attached to the rim of the Ferris Wheel.
These passenger seats can freely pivot at the support where they are connected to the Ferris wheel. As a result, the gondolas always hang downwards at all times as the Ferris wheel spins. they are kept upright, usually by gravity.
