possible paths of flight. For example, if it is thrown against the wind, it might sail along flat for a while, suddenly rise as high as a house, and then finally return to the starting point. If it is thrown with the wind, it will not return.
Never throw your boomerang from the midst of a group of your friends, nor when there are people standing anywhere near the spot where it may return.
You can make a small model boomerang out of a piece of cardboard and observe its path of flight. In this case it is important to make one arm a little wider and shorter than the other and to twist it at a slight angle to the long arm. To throw a paper model, lay it on the edge of a book, and flick a pencil sharply against the extending arm. It will shoot up, turn rapidly and then approach the starting point in a large curve.
When you are playing with boomerang along with your friends, it is very important to be careful as much as possible, because if its hits anybody they can be badly hurt.
