Astrid raised her hand again and said, "Sir, rides that are designed to be quickly set up and taken down, thus helping the carnival operator in moving them."

She looked over the textbook and added. "Some rides are for young children and may include a Carousel, Miniature Railway, Miniature Roller Coaster, or an inflatable bounce house. For older children and adults there can be many different types of rides. These rides are designed to use height, speed, g-force or centrifugal force to appeal to the riders senses. Some examples are the Chair-O-Planes, Ferris wheel, Zipper ride and the Tilt-A-Whirl."
