A boomerang is a thrown tool, typically constructed as a flat airfoil, that 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 sport, and entertainment. They are commonly thought of as an Australian icon, and come in various shapes and sizes.
Description
A boomerang is traditionally a long wooden device, although historically boomerang- like devices have also been made from bones. Modern boomerangs used for sport are often made from thin aircraft plywood, plastics such as ABS, polypropylene, phenolic paper, or even high-tech materials such as carbon fibre-reinforced plastics. Boomerangs come in many shapes and sizes depending on their geographic or tribal origins and intended function. Many people think of a boomerang as the Australian type, although today there are many types of more easily usable boomerangs, such as the cross -stick, the pinwheel, the tumble-stick, the Boomabird and many other less common types.
An important distinction should be made between returning boomerangs and non-returning boomerangs.
