Introduction: Make an Amazing Sports Noisemaker!

Sound off like a Semi! These noisemakers are perfect for sporting events and parties. The effect is similar to the air horn on a semi or a train. Everyone around you will want to know where they can get their own. Or they will move away and give you more room. Either way works for me.

Step 1: Short Video


Step 2: Tools Needed

Hot melt glue gun, X-acto knife, Drill press or Drill, Forstner or Spade bits

Step 3: Materials

Rubber Bands, Latex Balloons, Plastic Plumbing "tee" (from Lowes, Home Depot, Menards, about $2.00), Prescription pill bottles

Step 4: Prepare Inner and Outer Tubes

You need to make a tube in a tube. We have used many different materials for the tubes, including pvc pipe, film canisters and chapstick tubes. The pill bottles in the illustration are called "20 Dram" and "30 Dram" sizes. If there is a childproof tab, cut it off carefully so the small bottle fits inside the big bottle.

Step 5: Making Holes

Drill a hole in the bottom of each bottle. The inner tube needs to fit snugly into the outer tube. In our example, the outer bottle used a 1&1/2" Forstner bit and the inner bottle used an 1&1/4" bit. The size of the hole on the inner bottle is not critical. The fit between the inner and outer bottles will be caulked, so you have a little leeway, but in our example they fit like a glove!

Step 6: One More Hole

Make a smaller hole for the "tee" in the upper 1/2 of the larger outer tubes. Be sure to make your matching holes at the same level if you want the tubes to be even. It will work if they aren't, but it looks nicer when they are even. The example used a 1/2" Forstner bit to fit the tee.

Step 7: Hot Melt!

Time to start putting it all together. Run a bead of hot melt glue, caulk, or epoxy if you wish, around the seam of the inner and outer tubes. Set the open ends (the tops) down on a flat surface while the glue hardens. You want the inner and outer tops to be level with each other. The bottom can stick out any length, but the tops need to be as close to level as possible.

Step 8: Add the "tee"

Insert the "tee" into the side hole and run a bead of hot melt glue around it. Do the same thing to the other side and you are almost done.

Step 9: Add Balloon Diaphragm

Stretch a cut balloon over the top and secure with a rubber band. Pull the balloon as tight as possible for the loudest sound. A looser balloon will give a saxophone like tone. Tune the noisemaker to give a harmonious, resonating tone. The louder the better, of course.

Step 10: Options

Don't forget, you should customize your horn! Use team colors for your balloons, add stickers, write with a Sharpie and add a lanyard to hang around your neck, allowing your hands free to ring the cowbells I know you brought.

Step 11: Diagram of Concept

In response to questions about how this works, I have included a cut away diagram.  The air enters on the side of the outer tube, travels up under the balloon diaphragm, and out the center tube.  You can use this info to make your noisemakers out of other materials.

    I just built one of these today. Works great. I am hoping to adapt it to use on an electric bicycle as an air horn similar to the commercially made Airzound. Thanks for the good start to my project.

    I work in a pharmacy, so I was naturally drawn to the use of prescription vials in your design. I used the Rexam 16 and 30 dram vials and they worked perfect. I really can't believe the sound you can get with very little blowing needed. I giggle like a little girl every time I blow into it. You really made my day with this one. Nice work!

    Is there an easier way to make the holes? because : -i have No power tools (except hammer,heavy duty pliers,etc..) -even if i did, i wouldnt be allowed or even ABLE to use them! ~~> so is there any easier way?

    Gosh, I haven't been on in months. I just thought that perhaps another way to make the holes might be with heat. How about a soldering iron or gun? That would melt the holes pretty quick.

    Made one yesterday. The volume is incredible. Thanks for posting this instructable. I only made a single, but may try double when I get more medicine bottles.

    I don't the prescription bottles at home and I doubt anyone will sell them to me empty.  Ideas or what other cylindrical objects will work? PVC pipe inside one another?

    You could use plastic vitamin or headache pill bottles too.  Check your neighbours' blue bins on garbage day.

    Nice one, what great fun!

    I made a variation of this instruckable and this one
    https://www.instructables.com/id/Blow-your-own-air-horn/  out of a toilet paper tube as a proof of concept experiment.  The possibilities are endless.

    I strengthened the open ends of the toilet paper tube with “caps” cut from the sides of a 1 gallon plastic milk bottle hot glued to each open end as described below.

    One end was more like a real cap that was about 1/8“ bigger in diameter than the toilet paper tube opening with a hole cut in the center for a straw to slide in snuggly and the other end was more like a narrow ring that over hung the outside of the toilet paper tube opening about 1/8“ and also over hung the inside and of the toilet paper tube by about 1/8 inch too.  A bit like a washer with a large opening in the center.  This was the end that got the balloon stretched over it.  Both “caps" where firmly hot glued in place.

    A hole roughly about 1/4 inch in diameter was cut in the side about half way between both ends of the toilet paper tube and this is where you blow into it.  

    Stretch the balloon over the “washer” like cap and insert  the drinking straw (bigger the better)  into the other end touching the balloon “diaphragm”.   Adjust the position and pressure of the straw against the balloon while blowing into the hole in the side to get it to work.

    The softness of the toilet paper tube muffles the sound but it proves the concept and worked.  I await the next empty vitamin/pill/aspirin  box to make one for real!

    oh yes!  i have made them from a number of other cylindrical objects.  Pvc pipe was a little overkill, but very sturdy.  If you have a Walgreens near you, they might be willing to let you have a few at cost.  30 dram and 20 dram are what they are called.  We used to let people buy a few for maybe 50 cents each.  Other objects used were film canisters and chapstick tubes.

    awesome! I've never seen a 3yr old jump so high!  I finally matched his everyday decibel level
