Frisbee - online puzzles

A frisbee (also called a flying disc or simply a disc) is a gliding toy or sporting item that is generally plastic and roughly 20 to 25 centimetres (8 to 10 in) in diameter with a lip, used recreationally and competitively for throwing and catching, for example, in flying disc games. The shape of the disc, an airfoil in cross -section, allows it to fly by generating lift as it moves through the air while spinning.

Flying discs are thrown and caught for free-form (freestyle) recreation and as part of many flying disc games. A wide range of flying disc variants are available commercially. Disc golf discs are usually smaller but denser and tailored for particular flight profiles to increase/decrease stability and distance. The longest recorded disc throw is by David Wiggins, Jr. with a distance of 338.0 meters. 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; they typically travel significantly farther than any traditional flying disc. There are also illuminated discs meant for nighttime play—they are made of a phosphorescent plastic or contain battery-powered light -emitting diodes or chemiluminescent glowing sticks.
