Shuttlecock
A shuttlecock, sometimes called a bird or birdie,[1] is a high-drag projectile used in the sport of badminton. It has an open conical shape: the cone is formed from sixteen or so overlapping feathers, usually goose or duck and from the left wing only, embedded into a rounded cork base. The cork is covered with thin leather.
The shuttlecock's shape makes it extremely aerodynamically stable. Regardless of initial orientation, it will turn to fly cork first, and remain in the cork-first orientation.
The name shuttlecock is frequently shortened to shuttle. The "shuttle" part of the name was probably derived from its back-and-forth motion during the game, resembling the shuttle of a loom; the "cock" part of the name was probably derived from the resemblance of the feathers to those on a cockerel.
The "Shuttlecock" also used in traditional Chinese sports called "TiJianZi" by Chinese spelling, or "Shuttlecock kicking" in English. There is a lot of kinds and sizes of shuttlecock in the sports. The shuttlecock by size 15-15x14-15x14-16 cm of weight 24-25 grams is called "Middle Shuttlecock", usually used in "Chinese JJJ" game. It's a most popular shuttlecock kicking game with 90 cm height middle net and using inner lines of badminton court, which invented by Mr. John Du in May 2009. Chinese JJJ uses Soccer's shooting goal techniques in the game, making the shuttlecock sports much closer to Soccer Sports which is the first time happened in the history.

[edit] Feathered vs. synthetic shuttlecocks
The feathers are brittle; shuttlecocks break easily and often need to be replaced several times during a game. For this reason, synthetic shuttlecocks have been developed that replace the feathers with a plastic skirt. Players often refer to synthetic shuttlecocks as plastics and feathered shuttlecocks as feathers.
The cost of good quality feathers is similar to that of good quality plastics, but plastics are far more durable, typically lasting many matches without any impairment to their flight.
The playing characteristics of plastics and feathers are substantially different. Plastics fly more slowly on initial impact, but slow down less towards the end of their flight. Feather shuttles may come off the strings at speeds in excess of 320 km/h (200 mph) but slow down faster as they drop. For this reason, the feather shuttle makes the game seem faster,[citation needed] but also allows more time to play strokes.
Most experienced and skillful players greatly prefer feathers, and serious tournaments or leagues are always played using feather shuttlecocks.[2] Experienced players generally prefer the "feel" of feathered shuttlecocks,[citation needed] and assert that they are better able to control the flight of feathers than of plastics. Because feather shuttles fly more quickly off the racquet face they also tend to cause less shoulder impact and injury.[citation needed] In Asia, where feather shuttlecocks are more affordable than in Europe and North America, plastic shuttlecocks are hardly used at all.[citation needed] All senior international tournaments use only feather shuttlecocks of the highest quality. Also as opposed to feathers that self correct and drop straight down on the clear shot, plastic never quite returns to a straight drop falling more on a diagonal.
[edit] Specifications
A shuttlecock weighs around 4.75 to 5.50 grams (0.168 to 0.194 oz). It has 16 feathers with each feather 70 millimetres (2.8 in) in length. The diameter of the cork is 25 to 28 millimetres (0.98 to 1.1 in) and the diameter of the circle that the feathers make is around 54 millimetres (2.1 in).
