Materials Required:
- Cardboard
- Pencil
- Scissors
- Book
Procedure:
- Draw a V-shaped pattern like the one shown in the illustration on a piece of smooth, stiff cardboard. Cut it out, making sure the corners are rounded.
- Hold a book in your left hand, with the binding pointing upward at an angle. Place the V-shape cardboard on the book so that one arm may hang off the side.
- Hold a pencil along the side of the book. Quickly, move the pencil forward and strike the cardboard so that it may spin and fly off the book. In a few seconds, the cardboard will be back at your feet!
This is what happens:
You have just made a boomerang. Because of its shape, the boomerang returns to the thrower, continuing to spin in the same path without turning over. Boomerangs, used by native Australians and usually carved from wood, can be used as weapons or for hunting or just for the fun of it.
