Boomerang 回飞棒
Boomerang is also called “heavier‐than‐air” flying machine. King
                                  Tutankhamen of Egypt had an extensive collection of it for over
                                  2000 years ago.
                                  It was developed from a flattened throwing stick, used by early
                                  hunters. The returning boomerang was accidentally discovered by
                                  an early hunter while fine tuning a hunting stick.
Modern boomerangs can stay up in the air for several minutes and can reach a distance over 200 yards.
There are two types of boomerang, smaller boomerang is used for sport and is thrown so it would
return to the thrower while the larger war boomerang does not return and is used for hunting and
warfare.
