- Two pieces of fiberglass or plastic screen. (Do not use any type of metal screen)
- One piece of clear plastic pipe. (I used the tube from an old gravel vacuum for this one)
- Two P.V.C. pipe couplings. (These must fit over the end of the clear pipe)
- A section of airline.
- An airline gang valve. (You can get one of these at your local petstore)
- A suitable air pump.

Wrap one of the pieces of fiberglass screen over one end of the clear pipe and cap it with one of the PVC pipe couplings.
Wrap and cap the other end of the pipe same as step #1.
Trim away excess screen material. You can use a razor blade to trim it up after the scissors if you want.
Cut an "X" just big enough to slide airline into one end of the screen.
Slide one end of the airline into the "X".
Attach the gang valve and air pump as shown.
