. . . that I do not find this irritating at all?
It sounds like a cross between one of those nutty medieval instruments — what is it called, a flageoblat or something — and those straw kazoos we used to make. You know how to do that, right? Just bite down on the end of a plastic drinking straw to flatten it, cut the corners off to make a “reed” to vibrate against itself, and blow hard. Yeah, like this:
With some experimentation, you can figure out where to cut holes to play an octave.
You can also make a straw trombone — just slightly crush the end of one straw until it fits inside another. Cut a mouthpiece in the end of the outer straw, and slide the other straw in and out the other end as you blow. IT IS FUN, okay?
