How to Make a Simple Boomerang
Just to show the principle of the boomerang you can make a toy one and see for yourself how it acts. Cut a boomerang out of heavy cardboard about 6 inches long and make it the exact shape shown at A in Fig. 2.
To project it into the air lay a book upon a table and slip a piece of wood about an inch thick under one end so that the book sets in a slanting position. Now lay the boomerang flat on the upper surface of the book with the long end sticking out about 2 inches as shown at B in Fig. 2 and flip it sharply with the end of a pencil when it will sail through the air and return to the place it started from, nearly.
Magicians make an ordinary playing card do the same thing and you can too if you practice long enough. Hold a corner of the card between your first and second fingers and let the other corner rest against the ball of your thumb; then give it a spinning twist and throw it at the same instant into the air and it will return to you again.
