WHAT WILL YOU NEED?

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.
