Can you tell me about frisbee today?

Answer 1

Flying discs (commonly called Frisbees) are disc-shaped objects, which are generally plastic and roughly 20 to 25 centimeters (8-10 inches) in diameter, with a lip. The shape of the disc, an airfoil in cross-section, allows it to fly by generating lift as it moves through the air while rotating. The name Frisbee is a registered trademark of the Wham-O toy company, but is often used generically to describe all flying discs. Flying discs are thrown and caught for recreation, and as part of many different flying disc games. A wide range of flying disc variants are available commercially. 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. Ring shaped discs are also available which typically fly significantly farther than any traditional flying disc. There are illuminated discs meant for night time play which use phosphorescent plastic, or battery powered light emitting diodes. There are also discs that whistle when they reach a certain velocity in flight.
