What is Boomerang?
A boomerang is a tool, typically constructed as a flat air foil that, when thrown, is designed to spin about an axis perpendicular to the direction of its flight. A returning boomerang is designed to return to the thrower. It is well known as a weapon used by Indigenous Australians for hunting.
Boomerangs have been historically used for hunting, as well as a sport, and entertainment. They are commonly thought of as an Australian icon.
