Making a working paper boomerang is a fun craft for children, as it is an easy project that can be completed successfully with only a few household materials and a little bit of time. Flying paper boomerangs with children is a great way to teach them about scientific principals such as air resistance and gyroscopes. Experiment by launching the boomerang at different angles to see which method results in the boomerang coming back to you.
Lay a 4-by-6 index card or piece of cardboard on a table and measure 1/2 inch up from the lower left corner. Draw a line from this point to a point in the centre of the top edge of the index card. Repeat the process on the right side of the card, so that a large upside-down "V" is formed.
Cut along the two lines. Your index card will now resemble a pentagon.
Measure 1/2 inch inward from the lower left corner and make a small dot to mark the point at the bottom of the index card. Repeat this step on the right side.
Make another point directly 1 inch below the top centre point. Connect these three points to form the shape of your boomerang.
Cut along the lines to complete the paper boomerang.
Lay the paper boomerang on the palm of your hand with the corner of the boomerang facing away from you. The right edge of the boomerang should be hanging off of your palm.
Tilt your left palm upwards so your fingers are facing the ceiling and the boomerang is at a steep angle.
Stick out the index finger on your right hand and slide it quickly along the palm of your left hand so that it hits the right edge of the boomerang and launches it into the air.
Keep practicing until the boomerang comes back to you.
