STEP 1
Drill Holes
- Drill a hole through the PVC pipe one inch away from the end.
- Now drill a hole through the wooden dowel at its center. The hole should be just large enough for the string to fit through.
STEP 2
Attach the Dowel
- Cut a hole into the middle of the sponge emery board that is large enough for the dowel to fit through.
- Secure it to the emery board with glue
STEP 3
Bend the Board
- Once the glue is dry, bend the ends of the emery board in opposite directions as seen in the photo.
- Insert the dowel into the PVC pipe.
STEP 4
Add the String
- Thread the string through the hole that you drilled in the PVC pipe and then through the hole that you drilled in the dowel (see picture).
- Turn the dowel so that the string winds around it until there is a small piece left hanging out of the PVC pipe.
- Hold the pipe vertically and pull the string out as hard as you can!
- If your chopper doesn’t fly away, then try turning the dowel in the opposite direction when you wind up the string.
