Make a Super Loud Whistle With an Acorn or Other Pocketed Object





Introduction: Make a Super Loud Whistle With an Acorn or Other Pocketed Object

Someone showed me this with an acorn a few years ago. Once you figure out how to do it well, you can use all sorts of objects to make a super loud whistle. This is handy if you are lost in a forest, just want to get someones attention, or if you want to ref an impromptu soccer game.

Caution as this is so loud, you may not want to try it indoors!

Please check out my other instructables and I also have a diy podcast called

Step 1: The Hands

hold your hands so your thumbs are touching like the picture below. Rotate your hands open slightly like you are making a butterfly shadow puppet (see second picture) Note the "V" shape created at the top of your thumbs.

Step 2: Holding the Acorn Cap

You want to hold the acorn cap so it is totally sealed all around except for in the "V" shape you made with your thumbs.

Please excuse my hands, as an industrial mechanic, this is about as clean as they ever look.

Step 3: The Blow

Press your lower lip gently against your thumbs as shown, your upper lip kind of sits on top.

Blow hard. It will probably take a bit to figure it out right but when you get it, it will be loud!

Step 4: Video Examples

In these examples the sound does not do it justice.

Good luck

    My dad taught me this! Great trick!

    That is probably one of the coolest things I have ever seen. First principles;what is actually going on with a whistle, why is it louder than when you just whistle with your lips?

    super simple and super awesome! thank you!

    Great Instructable. The wife and I about hyperventilated trying different things.

    "The wife" - Originally used by Kipkay. It should stay that way mate ;)

    I've heard tons of people besides kipkay say the wife.

    I wrote that being completely unenlightened to the fact that it was a southern sort of phrase (at least, I don't think I've met any Northerners that use it). Feel free to flame me for being a noob at linguistics.

    my father taught me this technique years ago, i glue a bottle cap and a beer top together an carry them around(fr the different pitches)
