High Quality Content by WIKIPEDIA articles! The Yo-Yo is a common amusement ride featured in carnivals, state fairs, and similar events. A variation of the Chair-o-plane, it resembles a series of swings arranged in a circle, which turn just fast enough to be slightly affected by centripetal force. On some rides, there is a tilting mechanism, allowing the ride to tilt up to 10 degrees. Unlike the Zierer Wave Swinger, Watkins Swinger, Intamin Flying Dutchman, or Chair-O-Planes, the Yo-Yo has a more intense tilting motion; therefore, the seats feel like they will hit each other during the ride. Because of this, not only is the ride equipped with a standard metal lifting lapbar, but a snug seatbelt around the waist. Extremely large riders may not fit. Most Yo-Yo rides have a passenger height requirement of 46 inches tall or more.
