Boomerang: object that counts centuries! Characteristic of native Australians. Part of daily lives; come to our days owing to the peculiar use. Was it a weapon? A game? Its elliptical shape is what makes it create a path in the air. The beginning of its path is initiated by the user, and it returns right back to him. To use the Laws of Physics, unknown at the time! These are all interesting to see the use of this object, its shape better and intervening creatively, to convey in our everyday life. A simple form of American walnut, with a metal addition at the end, resting on the floor and on the wall, allowing us to hang any garment.
