The boomerang is the first flying instrument heavier than air to have been invented by humans. There are two possible meanings for the term “boomerang.” The first comes from the Turuwals, an Aboriginal tribe from New South Wales. When they caught the flying object, they exclaimed “boom-ma-rang,” meaning “Come back, stick!” The second comes from the Aboriginal term “boomari,” which means “wind.” 

Boomerangs are generally made from a piece of wood carved from an acacia or eucalyptus branch. The Aboriginals had many uses for the boomerang: hunting, games, and music. Thus, the boomerang can take different forms depending on its use. 

Here, the curved shape of the boomerang indicates that it was made for recreational purposes.
