boomerang (redirected from Boomerang world cup)

boomerang (b`mərăng'), special form of throwing stick, used mainly by the aborigines of Australia. Other forms of throwing sticks were used by the peoples of ancient Egypt, Ethiopia, and India and by the indigenous peoples of the SW United States. The boomerang is sickle-shaped with arms slightly curved in opposite directions as in a propeller. The trajectory of a boomerang is usually an arc, but in some cases it is a full circle. The boomerang of the Australian aborigines (from whom the name is derived) is made in two types. The smaller boomerang, 12 to 30 in. (30 to 75 cm) long, is used only for sport and is thrown so that it returns to the thrower. The larger war boomerang is 24 to 36 in. (60 to 90 cm) long and does not return; it is used for hunting and warfare.

boomerang

Curved throwing stick used chiefly by the aborigines of Australia for hunting and warfare. About 12–30 in. (30–75 cm) in length, the returning boomerang varies in shape from a deep curve to almost straight sides of an angle. The ends are twisted or skewed in opposite directions. It is held at one end, above and behind the thrower's shoulder, and swung forward rapidly. Just before release, the thrower adds spin by flicking the wrist so that the stick will loop around and return to him. Returning boomerangs were used only in eastern and western Australia as playthings, in tournament competition, and by hunters to imitate hawks for driving flocks of game birds into nets. The longer, straighter, and heavier nonreturning boomerang can kill animals and even humans.
