Frisbee
A frisbee, also called a flying disc or simply a disc, is a gliding toy or sporting item generally made of injection-molded plastic and roughly 20 to 25 centimetres in diameter with a pronounced lip. It is used recreationally and competitively for throwing and catching, as in flying disc games. The shape of the disc is an airfoil in cross-section which allows it to fly by reducing the drag and increasing lift as it moves through the air, compared to a flat plate. Spinning the disc imparts a stabilizing gyroscopic force, allowing it to be both aimed with accuracy and thrown for distance.
