How to Make an Origami Boomerang

2010-08-14T01:13:00.000-07:00

A boomerang is a flying tool with a curved shape used as a weapon or for sport. Although it is usually thought of as a wooden device, modern boomerangs used for sport are often made from carbon fibre-reinforced plastics or other high-tech materials. Historically, boomerang-like devices have also been made from bones. Boomerangs come in many shapes and sizes depending on their geographic or tribal origins and intended function. The most recognisable type is the returning boomerang, which is a throwing stick that travels in an elliptical path and returns to its point of origin when thrown correctly. A returning boomerang has uneven arms or wings, so that the spinning is lopsided to curve the path. Although non-returning boomerangs throw sticks (or kylies) were used as weapons, returning boomerangs have been used primarily for leisure or recreation. Returning boomerangs were also used as decoy birds of prey, thrown above long grass in order to frighten game birds into flight and into waiting nets. Modern returning boomerangs can be of various shapes or sizes as can be seen in the diagram of modern Boomerangs to the right of page.
