A boomerang is a curved, spinning throwing tool designed to return to the person who threw it, built with special wing-like shapes that make it fly in a returning path. The tool has been used by Aboriginal Australians and other cultures for hunting and sport, and the word itself comes from an Aboriginal Australian language.
