Finger Boomerangs
SUBJECT: Aeronautics
TOPIC: Boomerang
DESCRIPTION: Plans for making and flying small boomerangs made from
file card paper
CONTRIBUTED BY: Gregory Vogt, OSU
EDITED BY: Roger Storm, NASA Lewis Research Center
MATERIALS:
File card
Scissors
Pencil
Pattern
PROCEDURE:
1. Cut out the patterns of the
boomerangs and trace them
onto a file card.
2. Cut out the boomerangs from the file cards. SOME SAMPLE SHAPES
ARE SHOWN HERE.
Lay
the boomerang on the edge of a book and tilt the book slightly upward.
The book will serve as a launching platform. Using one of your index fingers,
strike the boomerang so that it spins rapidly as it shoots rapidly off
the book. The boomerang should fly straight out, turn, and come back. If
necessary, give the boomerang a bit of additional lift by bending the leading
edge tips of each wing slightly upward like a forward facing flap.
DISCUSSION:
Refer to the Four-Wing
Bomerang Activity for more information about boomerangs.
