Aus Wikipedia. Nicht dargestellt. Auszug: Flying discs (commonly though incorrectly called Frisbees as noted below) are disc-shaped gliders, which are generally plastic and roughly 20 to 25 centimeters (8-10 inches) in diameter, with a lip.

Disc golf discs are usually smaller but denser and are tailored for particular flight profiles to increase/decrease stability and distance. Disc dog sports use relatively slow flying discs made of more pliable material to better resist a dog's bite and prevent injury to the dog. Flying rings are also available which typically fly significantly farther than any traditional flying disc. There are illuminated discs meant for night time play that use phosphorescent plastic, or battery powered light emitting diodes. There are also discs that whistle when they reach a certain velocity in flight.
