Boomerangs are curved pieces of wood used as a weapon for leisure. Boomerangs originate from the Aboriginal people in Australia and have entered the mainstream as an outdoor pastime. There is no standard size a boomerang comes in. The size of the boomerang depends on the where it is made and what the purpose of it is.
There are different types of boomerangs for different uses. The most popular type of boomerang is the returning boomerang that once thrown returns to your hand. You have probably seen it many times and it is easily recognizable because of its curved shape. Even though not all boomerangs are made to return when thrown the ones that do, do so because of their shape. In most cases boomerangs are light weight pieces of timber and recently hard plastic.
Although the boomerangs seems to be a simple wooden object there is a lot of science behind it.There is no magic involved in this process or no tricks. Boomerangs return because of the laws of physics that work in relation to their distinct shape.
Returning boomerangs have slightly different shape than non-returning ones. The ones that return do so because they use the drag to lift and fly sideways by turning. Boomerangs fly because of the high pressure that develops underneath their wing while the top creates a low pressure area.
Keep in mind that in the returning boomerang one wing, the wing arm is a bit different than the handle one. As a result when thrown in the air one pulls the other in an angle. As it continues its flight the lift from the one corner makes the boomerang to at some point turn back and head to its starting position.
Whether a boomerang will return or not also depends on the way it is thrown. This requires some practice because it is important to get the right amount of spin in the throw. The right way to throw a boomerang is to tilt and gently pull the one side while you are throwing it away. This way you will increase the chances of it returning to your hand.
