According to the 3d print groups lately, these are the new things all the cool kids are using to cause massive disturbances in the glorious silence.

Ocarinas are among the oldest wind instruments dating back to prehistoric times. Some people call them potatoes.

You have to play it for us, once it's done.

Your actually volunteering to be tortured ???? Ya realize last time I tried to play anything it caused 3 suicides and 7 people poked their eardrums out to escape !!!!

I've got a roll of Lava filament kicking around, it goes from black-dark green-tan-orange-yellow with temperature changes. I'm thinking kids will go mental over a raptor resonator that changes colors wherever they touch it or blow into it. Worth a shot anyway to fleece the parents while the brats piss off everybody in earshot....er....I mean, provide their wonderful children with hours of joyful entertainment. .

Print it out of a hard material, it will sound better and louder. A soft material will dampen the vibrations of the air, and the sound comes from the air. It is a fipple flute, like a whistle or a recorder.

Apparently, I am only capable of using this thing as a whistle.

I can get it to make noise out of one hole only, and as soon as I cover that one up it goes Simon and Garfunkel. Ah, well, they aint meant for me anyway.

Turned out nice though. And it took 20 minutes for the first order.

It depends on a pressure wave generated at the open hole nearest to the fipple. That wave travels back to the fipple and bounces the air column upwards, briefly lowering the pressure in the chamber.

Look for obstructions, slag, anything that might disrupt the pressure waves. Try covering all but the farthest hole from the fipple. Try varying your air speed/pressure. Too much pressure can overwhelm the returning wave.

You are not covering the fipple are you?
