I Mentioned this about six weeks ago and thought I would show you how to make them if you haven't seen it already. I saw this on Turkey Call a few years ago.



You start with a pill bottle that has a cap that is NOT child proof. It just snaps down to close it. I used a coping saw to cut the end off.

Then I cut a half moon shape out of the lid with a stanley knife. You can make this too large which makes it difficult to seal the sides while blowing into the call.

You might want to start small and make it larger to get the right sound.

I'm showing you the inside of the lid to show you that it is a very simple, snap on lid. I've found some that have a second ridge on the inside which doesn't work for the turkey call.

Next, take a strip of latex from a rubber glove, like they use in hospitals, a stretch it over the opening of the bottle leaving a gap and snap the lid over top of it.

Place your upper lip above the straight part of the opening and blow into it while "saying", "yuck, yuck, yuck". You'll have to practice with it and play with the placement of the rubber glove strip to get the right sound, but it works.

that's pretty cool Bona.

You can also use a 35mm film cannister.  Thanks.
