A boomerang is a curved, usually wooden, device which is thrown. A boomerang spins as it flies through the air, and can travel long distances. A boomerang is designed to, when thrown correctly, fly a curved path to return to the person who threw it
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, and come in various shapes and sizes.
