Throwing the Boomerang
You have probably heard about the boomerang, that small piece of carved wood that, when thrown, returns to the thrower, and wondered about it. No other weapon or hunting device does that (which is actually a misconception), so it is a wonderful implement, even as a toy. At least for someone who knows how to throw it; otherwise, it is just a piece of wood, or, as most put it, a stick.
What makes it fly
But how does a boomerang fly? A boomerang’s shape is flat one side and convex on the other. It is thrown with the curved side up so when it whirls through the air, the flat shape produces a lifting action, much like an airplane wing. Since one arm of the boomerang is longer than the other, the longer part gives it impetus to move forward and in a circle when thrown correctly. Likewise, it is this longer arm that makes the boomerang flatten its flight path from near vertical, since it makes a infinitesimally little more lift than the shorter part.
How to throw a boomerang
There are generally two ways to hold the boomerang for throwing. First, the pinch hold. It consists of pinching the boomerang’s end (doesn’t matter which) between the thumb and forefinger like holding a key about to be inserted into the keyhole. Then there is the cradle grip, which is holding the boomerang like you’d hold a hammer or tennis racquet, the boomerang arm well inside the closed fist. Either way, use the grip that is most comfortable to you.
Boomerangs are designed to fly with a little wind, although it can fly through dead calm and stronger gusting winds depending on how strong you cast. See how in another article here someplace
