Instructables
Its wintertime and the wind is blowing. Make these "Wind Hooters" instead of wind chimes to add errie sounds to your yard. You can turn them off at night by turning the slots away from the wind (if they bother your neighbors).

Step 1: Cut the slot

Picture of Cut the slot
Peel off the label and cut a slot lengthwise down the bottle about 1/4 to 1/2 inch wide and about 5 inches long. You can use a 2 liter soda bottle or even smaller bottles for the windhooter.

Step 2: Drill the cap

Picture of Drill the cap
Drill a small hole in the cap for mounting the windhooter down. I used a strip of 2 by 2 and mounted down several bottles.

Step 3: Insert a screw

Insert a screw in the hole and use this to hold down the bottle. The end of the bottle needs to be capped or it won't hoot.

Step 4: Mount in a row

Picture of Mount in a row
Mount several bottles in a row on a 2 by 2 piece of wood. Tie down the strip on a fence, railing or pole in your yard.

Step 5: Adjust slot in the wind.

The sound is best if the wind blows across the slot.. You can turn it off by twisting the slot away from the wind. Narrow slots or smaller bottles make higher notes. Experiment with different bottles and slots.

Step 6: Video

Here is a video of the sounds.

I got this idea from Plastorgan. This is a great project for the kids. Also check my webpage for more about the Windhooter.

A good tip for cutting these bottles or aluminium cans, is to fill them with water and freeze them solid. Once frozen, your scalpel can cut exact shapes into the plastic and ice easily.

Wonderful tip!! Thanks.

love that tip
It is a good tip as it makes cutting a whole lot safer and surer.
Made 3 today! a 2 liter, a 1 liter and a 20 ounce... all I need now are a 3 liter and a 16 ounce, lol. Put them on my Halloween Shed way up in the pasture behind my house and over the hill-perfect to annoy the neighbors up that way I can't stand!

Should sound plenty spooky at night!

I made many of these to annoy my neighbors. They worked great!

Good job. Wind Harps work too. I turn mine out of the wind most of the time to keep my neighbor happy. But it is fun hearing it when the wind picks up.
Our house gets this sound with very little wind, all on its own! It was strange when we first moved in, but now I rather like it.

Sounds errie,my window does it when we get a noreaster,no matter how warm I am the noise will still give me a chill.

I love it! Simple and fast, this will be a great addition to my yearly yard haunt to add spooky sounds in the graveyard. I can put them inside one of the mausoleums with a fan to blow across them and make spooky sounds. Thanks much!

This is so easy, I will have to try this, thanks for posting!

Why not add a swivel to your cap and then place a tail at a 90 degree angle to the slot (like a windmill). That way when the wind blows the bottle will automatically orient itself in the winds and start howling.
botronics (author)  baudeagle5 years ago
That would work. You can cut up a second bottle for the vane and use sheet metal screws to attach them.

Cool! My friends and I go through a lot of two-liters, so I've got enough bottles to experiment with. We've been having a heckuva wind here lately so it shouldn't be an issue, but for when thigs go back to sanity, any idea what kind of wind velocity you need to have them work?
botronics (author)  Rishnai5 years ago
That's a good question. Maybe 20 to 25 mph. Perhaps i should attach one to my car's bumper and note the speed. At least it would scare away the deer in the road.
And potentially scare off all the people, too...
Ya and ghosts and goblins too

Get enough bottles and you can build something like this at Burning Man called Siren's Song
Probably just my incompetence but I get no sound on steps 6 or 7. Guess I'll have to make one just to fin out what it does sound like. Thanks just right for a little winter project to keep our neighbor kids excited and learn a little science.

Here is a link to the Youtube help Center. Perhaps this may help.

What a great sound!
LOL!

When I made "Sirens of Taos" with my windharp, I clamped a windhooter to the frame. The sounds added to the background and made it sound errie. You can hear it at the link.

How adding a swivel to the mounting bar and a vane so that the bottles are always kept at the optimum angle to the wind? I doubt whether doing this in-line like a weather vane would work due to increasing turbulence, so the vane would have to be at 90 degrees on a rod to keep the whole bar of bottles facing the wind.
botronics (author)  AndyGadget5 years ago
You could swivel the mounting bar and use two bottles at one end with the slots perpendicular to the bar. Attach the caps so one bottle is up and the other is upside down. The bottles form the vane. As the wind blows it will line up perfectly. Or place them fixed in a circle with slots going different compass directions. The sound would change depending on the direction of the wind.

Awesome! But it sounds real eerie...
Brilliant!
