Boomerang

It is estimated that boomerangs first appeared forty-thousand years ago. The curious shape and its equally curious behaviour had many people think it had magical powers.  Initially, it was presumably a weapon used for hunting and in battle. Later it emerged as a sports implement. The first boomerang was brought back to Europe by Captain Cook in 1770. Throw it around as much as you like, but don’t move. Try it sitting in the water!
