Throwing the Cardboard Boomerang

Materials Required:

	Cut a slit of 1.5cm at one end of each pieces of the cardboard with scissors.
	Attach two pieces of the cardboard as illustrated.
	Place the third cardboard as illustrated by the arrow, and then turn it in the anticlockwise direction.
	Adjust the three pieces of cardboard so that they will each form the same angle.
	Wrap the ends of the cardboard with the tape (this adds weight and allows the boomerang to travel in a bigger circumference when thrown).

	Twist the wings of the cardboard as illustrated.

	Holding the boomerang as illustrated.
	Throw the boomerang vertically in front of you, using your wrist.
