68.80.12.36: /* Games */ Flutter frisbee is a game that improves catching skills.

While the word '''Frisbee''' is claimed as a [[trademark]] of the [[Wham-O]] toy company, the term is often used [[genericized trademark|generically]] to describe '''flying discs''' similar to those made by that company. They are generally [[plastic]], roughly 8 to 10 inches (20-25 cm) in [[diameter]], with a lip. They are designed to fly [[aerodynamic]]ally when thrown with [[rotation]] and can be caught by hand.

The shape and quality of frisbees varies significantly, and a high-quality frisbee easily flies several times as far as a cheap frisbee. [[Disc golf]] discs are usually smaller in diameter but are more dense and are tailored for particular flight profiles such as stability or distance. When it was discovered that [[dog]]s enjoyed chasing and retrieving the slow-moving discs, special frisbees were eventually designed with more pliable material that would more resist damage when the dog caught one in its mouth. [[Disc dog]] competitions, in which dogs' frisbee-catching skills are judged, have become quite popular as well.

Many frisbee-like discs are shaped like a frisbee with a large hole in the centre; such discs, known as ''aerofoils'', typically fly significantly farther.

The Flying-Saucer, originally invented by [[Walter Frederick Morrison]] and codeveloped and financed by [[Warren Franscioni]] in [[1948]], was unsuccessful, but a later model made by Morrison in [[1955]] and sold as the "Pluto Platter" was bought by Wham-O in [[1957]]. Wham-O renamed the toy in [[1958]] to "Frisbee", a (probably deliberate) misspelling of the name of the [[Frisbie Pie Company]] of [[Bridgeport, Connecticut]], whose [[pie]] tins had been used by Yale college students in the area for similar purposes. The first flying discs were produced on [[January 13]], 1957.

==Physics==
The disc's rotation creates an [[angular momentum]] perpendicular to the horizontal plane, stabilizing the disc's [[Aircraft attitude|attitude]] in high-speed flight. Small ridges near the leading edge act as turbulators, reducing flow separation by forcing the airflow to become [[turbulent]] after it passes over the ridges. Lift is generated in primarily the same way as a traditional asymmetric [[airfoil]], that is, by accelerating upper airflow such that a pressure difference gives rise to a lifting force.
