Introduction: Tiny Tootophone

Picture of Tiny Tootophone

The tootophone could be the People's Instrument of the 21st Century.  You don't need to learn sheet music or memorize fingering positions to play just about any melody with it.  It can easily fit into a pocket, and it only costs about 25 cents to make.  The basic 1 cc insulin syringe costs about 15 cents. 

You can add pipe extensions to the body of the tootophone to give it a deeper, richer voice.  A variety of tootophones could make some very interesting music, I'm sure. 

To hear this tiny tooter in action, listen to the music samples in later steps. 

Step 1: The Reed Material

Picture of The Reed Material

From Wikipedia:  "A reed is a thin strip of material which vibrates to produce a sound on a musical instrument. The reeds of most Woodwind instruments are made from Arundo donax  ("Giant cane") or synthetic material; tuned reeds (as in harmonicas and accordions) are made of metal or synthetics."

Years ago, I borrowed a saxophone and couldn't get anything out of it except unmelodious squawks.  As an experiment, I sanded down some PVC plastic and made a replacement reed for it.  Still no great music, but at least it was easier to play.  The sax got returned and I continued experimenting, mostly with PVC pipe body instruments. 

Sanding PVC reeds was a lot of work, so I experimented with clear plastic packaging material I found in the trash.  It came in different thicknesses and with different degrees of rigidity.  Thinner material makes reeds that are easier to play.  Plastic reeds can be cut out of scavenged packing material with scissors.  

For your first tootophone, I suggest you go the easy route and just cut a reed out of scavenged plastic packaging material.  You can make mellower sounding reeds out of rubber, but it is more complicated, since you have to make the material.  (I haven't found off-the-shelf sheet rubber material for reeds yet.) 

I found that the traditional cane reeds were at the stiff end of the spectrum, followed by different kinds of plastic and rubber at the other extreme.  My first rubber reeds were made out of Sugru, a clay-like material that hardens like rubber.  That eventually led to my present favorite, a combination of fiberglass mat material and silicone rubber. 

I found that pure silicone rubber reeds were too floppy, so I increased their rigidity by adding cloth-like materials.  In this step I explain how I make fiberglass and silicone rubber reed material.  If you don't have the fiberglass, experiment with other synthetic cloth materials. 

1.  Start with a non-stick work surface, such as Teflon cloth, which I think is sold  for kitchen use.   What I use is a polyethylene plastic cutting board.

2.  Cut a section of fine fiberglass mat material big enough to cut out the number of reeds you want to make.  I usually make foot square sheets.

3.  With a palette knife, or similar tool, spread out an area of silicone rubber on the work surface big enough for the fiberglass material and set the material onto the wet silicone.  This eliminates any penetration problem from pressing the silicone through from above.

4.  Start at the center with the palette knife and press down and toward the edges, forcing silicone from below up through the pores of the material.   Make sure there is a reasonable layer of silicone on top.

5.  If you want 2-ply material, or thicker, repeat steps 3 and 4.  I use mostly 2 ply material.

6.  Let it dry several hours, or overnight before peeling it up. 

7.  Cut it into strips and sections long enough to serve as the reeds.  I use a paper cutter to cut the strips, which are about 1/4" wide. 

Step 2: Sanding the Mouthpiece by Hand

Picture of Sanding the Mouthpiece by Hand

The mouthpiece consists of a rigid part, and a reed attached to it that vibrates.  The rigid part is made of a 1 cc insulin syringe.  Large mouthpieces made from larger tubing tend to be louder, and need more lung power to blow. 

The syringe is sanded down with a curve against which the reed forms a tangent line.  When finished, I tape the reeds in place with electrical tape.  I wrap the electrical tape with nylon thread to keep the tape from coming unstuck. 

Sanding the curve is a bit of an art.  If you have trouble getting the high notes, the tip of the curve might be too straight.  I usually hold the reed in place with my thumb and blow to test it before taping it down.  I test it at different stages during its attachment. 

For mass production, I use a belt sander mounted to my workbench, but you can sand the curves by hand, too.  For small mouthpieces, stick a piece of wood inside them to hold onto. 

Try to avoid sanding your knuckles along with the mouthpiece!  Sometimes I use the finger from a rubber glove as a knuckle protector.  Use a forward and backward arm motion with a slight rocking motion at the wrist.  Sand the curve smooth, with no flat spots. 

You can use course, medium, and fine sandpaper.  As a final step, I use just plain drawing paper to get a polished smooth surface. 

After sanding the curve, you have to dress up the rough edges by scraping or cutting with a sharp knife.  I use a pointed X-acto craft knife.   Push the original plunger through to clean out any dust inside. 

Step 3: Sanding With a Power Sander

Picture of Sanding With a Power Sander

I make a lot of tootophones, so I came up with some special equipment to help with mass production. 

I mounted a belt sander to my workbench, upside-down, by drilling holes in the table and using wire to tie the belt sander down. I made a small PVC "table" next to the sander, held in a vise, to position the metal guides of the sanding tool on the same level as the sand paper.

The syringe slides in and out of the tight-fitting, heat-formed PVC holder on the side of the tool.  By rocking the metal guides on the flat PVC surface, the syringe is sanded down to a curve that matches the guides. 

With this set-up I can sand down hundreds of mouthpieces with reasonable uniformity. 

You have to finish machine sanding with a little hand sanding, using fine sand paper and then polishing with just regular paper.  Dress up the edges with an X-acto knife, or similar knife and fine sandpaper. 

Step 4: Attaching the Reed

Picture of Attaching the Reed

Cut rectangles of reed material a little over 1/4 inch wide (depending on the width of your syringe body), and about 1 7/8 inch long.  Position it almost to the end of the mouthpiece and hold it down with a thumb.  Test blow the reed.  If it sounds OK, tape down the other end with a little square of electrical tape.  Then press down the sides of the tape, making sure the reed doesn't shift. 

Then, starting at about where the hole begins, wrap the reed down with about three windings of tape.  Cut the tape. 

Once the reed is taped down, trim the two exposed corners of the reed with scissors to more closely conform to the shape of the mouthpiece. 

Electrical tape can sometimes come unstuck, especially if people wash the instrument.  To prevent the tape from unwinding, I hold it down by wrapping it with nylon thread.  See the picture for a description of how to do this.  Pulling one end of the thread pulls the other under the windings.  Trim the exposed thread ends and it's going nowhere. 

Step 5: Mouth Control

Picture of Mouth Control

Reed instruments are basically mouthpieces with tubular extensions on them.

Tootophones are single reed instruments.  The mouthpiece is shaped with a curve, and the player's lips press the reed against the rigid part of the mouthpiece at some point along the curve, creating a tangent line to the curve. 

Bend your lower lip in a little over your teeth and rest the reed at about the midpoint on the dry side of your lower lip.  You don't want a lot of saliva gumming up the reed, preventing it from vibrating.

Air blown through the space between the reed and the mouthpiece creates an area of low pressure, which pulls the reed upward until it closes off the air flow and the reed springs back.  The repeated opening and closing causes pulsing pressure waves in the air and the frequency of those waves determines the tone. 

Placing the lips closer to the end of the reed shortens the length of the reed and it vibrates faster, creating a higher tone.  Allowing the entire length of the reed to vibrate creates the lowest tones. 

I usually place my lips at about the midpoint of the reed, allowing me to vary the notes by varying the upward pressure of my jaw, and the strength of blowing.   The higher notes usually need more air pressure. 

Once you can get a sliding scale from low notes to high notes using mouth control, you can pick the notes you need for any melody out of the sliding scale.  This tiny tootophone covers about two octaves.  Fine tune and enhance the basic notes using your hands. 

Step 6: Hand Technique

Picture of Hand Technique

With stiff reeds, like cane, the traditional technique of opening and closing fingering holes works best.  With softer reeds, the holes don't behave the same and tonal changes are more easily achieved by not using fingering holes at all. 

Instead, cup the end of the mouthpiece, or instrument with your two hands, enclosing a ball of air.  Open and close your hands to create a wah-wah effect and to fine tune the basic note created by mouth and breath control.  Closing the hands creates more resistance to air flow and a lower tone, the same as having a longer column of air in a longer body does.  Opening the hands raises the tone. 

Step 7: Listen to the Tiny Tootophone

To hear the Tiny Tootophone, click on the icons below that look like pieces of paper with the corners bent over.  That should open up mp3 audio files. 

One file demonstrates the tiny tootophone with a rubber reed (deeper voice).   The other demonstrates the voice with a plastic reed. 

Step 8: Other Tootophone Variations

Any modification of the body will modify the sound.  Bigger and longer bodies give deeper voices.

i'm having soooo much trouble making one of these, is their a length specified for the sanded hole in the syring? and i was wondering if you sell these, because you could easily put them in an envolope and mail them, and i would pay $3 for the one with the x-ray plastic if you see this and you want to sale one or two, contact me at

Thinkenstein (author)fritolay222014-02-14

No, I don't sell them. Experiment with making longer and shorter curves. I think that the curve resembles 1/4 of an ellipse. Anyway think about that as you practice making a few. I learned by making a bunch of them. Hundreds, actually.

btiu (author)2013-01-16

Oh yeah. I have to say, glossy photo paper make great reeds, even without silicone. One downside to it is that the non-glossy side gets soft after a few uses. (I placed the glossy coated shiny side touching the tooter's body.)

Thinkenstein (author)btiu2013-01-16

Not very good longevity, if the reed gets soft after a few uses. Definitely, it's not the ideal solution, but it's great that you made a tooter. You can always replace the photo paper with other materials when they come along and learn something about how the different substitutions change the sound.

btiu (author)2012-11-30

I tried making my one. I used a plastic reed (specifically scotch tape sticking to itself; and also tried other plastic reeds). I end up with a middle ranged duck sound. Also, 1cc syringes available to me don't come with the cap that you made into a mute cap. Is there anything I can do to change the sound? Is it because of the missing mute cap or the type of reed I used? Please give me some alternatives. I'd like it to sound like a trumpet or a high woman/human voice. Thanks in advance.

Thinkenstein (author)btiu2012-11-30

My favorite plastic is from x-ray films, after cleaning off the image. Other similar gage packaging plastics work. I think your scotch tape reed was probably not stiff enough.

Anything that reduces the diameter of the throat will mute the sound. Less air passes through and less volume is possible.

All the varieties of reeds have their place in music. My favorite ones have thin layers of silicone rubber on x-ray film. Put some silicone on the film, with a piece of paper on top. Then squish it out with a printing roller. When dry, gently wash off the paper fibers with water. I coat the reed material on both sides, and then cut it in strips with a paper cutter.

There is a percussive overtone when the reed smacks the mouthpiece. Silicone against silicone is my favorite, with less tinny overtones. See my latest instructable, Silicone Rubber Tootophone Mouthpiece to see how my favorite mouthpieces are made now.

The syringe tooters are cheap to make, but sound tinny in comparison to the silicone ones.

Nice to hear that someone is actually making the tooters. Thanks for the feedback.

btiu (author)2012-11-30

Also, I forgot to mention. I haven't put silicon on any side. Will it help if I do? I don't want to lose too many high notes if possible. Love your invention.

Vace Cooper (author)2012-03-05

HA! I just played the hypo toot with some guy playing banjo on youtube... I was also smiling like a lunatic!

Thinkenstein (author)Vace Cooper2012-03-05

Sounds like you are well on your way to having fun with tooters.

Here's a Youtube video of me doing a tutorial for the basic tootophone made from an insulin syringe.

Vace Cooper (author)2012-03-05

awesome, i need to make one of these.

carpfluff (author)2012-01-08

everything is made from syringes. it seems pretty... unsanitary? disgusting? weird? i don't know.

Thinkenstein (author)carpfluff2012-01-08

Unsanitary -- no. Syringes are about the most sanitary products you can buy. Injection molded plastic packed for your protection. You have to understand, I get them at the pharmacy, not out of the trash at the hospital.

Disgusting? There is no accounting for personal tastes, I suppose.

Weird? I suppose it is only weird because you don't see them used this way all the time. Buy a few syringes, make tootophones, and help change all that!

carpfluff (author)Thinkenstein2012-01-10

okay. as long as they're not used or something. that would be the unsanitary/disgusting part. but it's cleared up now. thanks!

gangsan1996 (author)2011-02-18

do you take drugs? is that why u have so many needles?

Thinkenstein (author)gangsan19962011-02-19

I think the war on drugs does more harm than good, but no. I have so many needles because I need them to make so many totophones.

Thermonuklear (author)2011-01-30

Loved the sugru version :)
The mouthpiece is very similar to a traditional reed/straw whistle, I've made a few of them.

wolfcrane (author)2011-01-13

Being a diabetic, I'd love to see even more ideas on how to make stuff from old syringes. Thanks!

Thinkenstein (author)wolfcrane2011-01-13

I buy my syringes new. Recycling syringes might be a little problematical. It would be nice if all the use-once syringes could be recycled somehow.

wolfcrane (author)Thinkenstein2011-01-13

I buy them new too. I had meant that i would love to see more instructables on what to do with the used ones, instead of putting them in a sharps box.

Thinkenstein (author)wolfcrane2011-01-13

A sharps box is some sort of a collection container for used medical equipment, I take it.

Used syringes can be "defanged" to remove the needles and the risk of getting poked. That's the first thing I do with them, anyway.

After that, one has to trust they are clean after washing.

Besides slide whistles and tootophones, not much use for them occurs to me. If I had equipment to melt down and reform the polyethylene plastic, then it could become any number of things, but that would be on a more industrial recycling scale.

I can't think of any projects to use them up at the rate you are probably generating them.

Well, it's a good source of material for you to be considering. It would be neat if there was a home workshop way to melt down and extrude, or injection mold some of our waste plastics.

I wouldn't mind playing with something like a hot glue gun that could melt syringes down and extrude them. Maybe a hot glue gun would work? I'll have to try that out sometime when I feel like risking the glue gun.

tkjtkj (author)Thinkenstein2011-01-14

Great presentation! and the fact that you expanded your 'structable to include 'factory mode' of making lots of them was clever and appreciated.
As for recycling sryinges, it would involve cleaning and sterilizing .. In years past, where all were glass (including the plunger ..ground glass surface) they could be sterilized in an autoclave. Now, they are all gas-sterilized, which is definitely NOT a 'DIY' project! Im not sure what happens to the rubber-tip of a plunger in an autoclave: i'll try it .. but its not relevent to your project of course, cuz you don't use the plunger at all.
Which brings up an interesting point: what if you do use a plunger? varying the tone by changing tube length could be fun to try.. however without the 'lip control' you describe it'd be unlikely to be able to get more than one good note: ie, the 'resonant frequency of the cavity' ..

Also, for those concerned with 'legalities' : the device is NOT a sryinge at all .. It is a TUBE
not even a plunger, certainly no connector to attach any needle.. so there is NO 'possession' issue at all. If it were, you could be arrested for having a drainpipe on the side of your building: which is also a tube..
(Being a doc does make this easy for me to say ;)) )

Thinkenstein (author)tkjtkj2011-01-14

The plunger is good for making slide whistles. I can't see using it in a tootophone, because it would close off the air flow through the instrument.

tkjtkj (author)Thinkenstein2011-01-17

yes, that's reasonable, but (why does everything have a 'but..' haha) i remember that 'blade of grass' whistling device that we used to make as a kid: ya know: cupping one's hands and holding a grass blade between thumbs ... the result is a 'reed' type instrument NOT haveing a tube-like exit ..rather: thumbs form a 'bottle-top' device, and by changing hand shapes ya can do an entire octave .. i used to play 'Yankee doodle' that way , so it can be done. The reed, though, as you imply, would have to be repositioned so it vibe's as the air is blowing over the top of the tootophone , .. its just a thought .. maybe not worth pursuing ..

Thinkenstein (author)tkjtkj2011-01-17

I never even tried to get a melody from the grass blade. Congratulations!

A reed external to the tootophone would not take advantage of the tube, or conical ending that is part of the tootophone body, so it would be more limited.

I tried to make a grass blade type instrument, with adjustable tension for the blade. I used a rubber membrane instead of grass. Anyway, I wasn't impressed. The lip control of the tootophone reed is a lot more sensitive and quick than a finger trigger is.

tkjtkj (author)Thinkenstein2011-01-24

ya,i'm *totally* sure the tones etc from yur tootophone are far better!
The grass blade thing isnt all that difficult .. as you know, one cups one's hands in the exact same manner you do when not using the grass at all .. and blow across the joined distal knuckle of your thumbs .. The grass blade's one end is held between the fleshy-part of your hands below the thumb, and the other end of the blade is squeezed between the distal thumb joints, ..
flexing the tip of thumbs or extending them will stretch or shorten the blade .. its really quite accurate, if annoying to others!
(i gave the details here only for others who might not have had such a fun childhood ;)

Tamaresque (author)Thinkenstein2011-01-13

Hm, if only these were generally available we'd solve a lot of problems, not just syringe disposal!

wolfcrane (author)Tamaresque2011-01-15

I would love to see something like this at every landfill.

Thinkenstein (author)Tamaresque2011-01-13

Agreed. It looks like a promising way out of the plastic mess we have created.

wolfcrane (author)Thinkenstein2011-01-13

That would be a great idea, to melt them down for other projects.

conundrum2142 (author)2011-01-16

not exactly, this is an entirely different hack.

You can get very small bluetooth headsets so fitting the pcb internally with existing microphone and using a reed switch as the enable/power switch to make a compact cordless mic could work.


conundrum2142 (author)2011-01-16

i saw a plan in epe a while back for a "syringe logic probe" iirc.

These are ideal for such applications as the existing "end" can be removed and replaced with a sanded down (aka defanged) needle or just a blunt ended one from a printer repair kit.

i was toying with the idea of building a complete multimeter into one of these things with an audible readout as well as display taken from a cheap MP3 player.
that would be amusing :-)


You lost me. This would be a microphone pick up for the tootophone? Anyway it sounds like an interesting project. Go for it!

vonKaos (author)2011-01-14

Be serious!

Calorie (author)2011-01-14

If this were April Fools Day I wouldn't be so suprised. Sure, I'll take your word that it sounds good. But my God! If a cop saw one of these on you (or near you) you are going to be in a new level of hell.

I'm not criticizing anyone, the inventiveness is cool. But I was mystified how no one thinks that these look like a set of heroine works. And a cop ain't going to by the reed business. They've heard everything in the book, and then some. (And yes, I had an uncle who was a deputy.)

Well, good luck and keep these at home.

Thinkenstein (author)Calorie2011-01-14

Well, I have given away hundreds of these in town. It's admittedly a small town, and probably most of the police already know me. Anyway, the police station was the first place I started giving them away.

If the police were educated about this use for syringes, there would be less reason to fear them.

Likewise, if they would just call off this disgraceful and harmful War on Drugs, there would be less reason to fear them. Maybe people will someday see tootophones as a step in the direction of peace, turning cannons into plowshares.

spark master (author)2011-01-13

oboe reed and kazoo combined, interesting. I made same thing with a soda straw, nice though this holds up way better.

The tootophone is not a kazoo. You don't sing into it. It's a reed instrument that you just blow into, like a saxophone. I guess it can sound similar to a kazoo at times.

we hummed into kazoos, this is closer to a double reed, like an oboe? This is way way better then the strw thing I made since it is more rigid and has better tone, kudo's to you!!

This is a single reed instrument, like a saxophone. Make one and try it out. They are a lot of fun.

they look cool, I am looking for a needle as we speak. I have done this with soda straws.


Save Ferris (author)2011-01-13

I skipped straight to this step to hear the sample tunes. Now I HAVE to make this, and need to talk to my diabetic friend as soon as.

If you want to hear something special, then play Hypo Toot over this classical guitar piece on YouTube:

It's ridiculous but it made me smile like a lunatic. :¬)

geekdude (author)2011-01-13

sounds funny like something that could be used for cartoon sound effects

star folder (author)2011-01-13

A drinking straw can also be cut with the 'reeds' and then while blowing, use a pair of scissors to trim the straw a 1/4 inch or so either until you run out of breath, or the scissors get too close to your lips.

Thinkenstein (author)star folder2011-01-13

That sounds kind of like an unrepeatable melody.

I'm seeing plastic confetti.

dulciquilt (author)2011-01-13

check a gasket shop for rubber sheets

Thinkenstein (author)dulciquilt2011-01-13

Thanks. Will do.

carlpeb (author)2011-01-11

I've experimented with lots of different ways of making sound and not really got round to exploring single reeds properly - you've inspired me! A fantastic sounding instrument with bags of character and an absolutely brilliant instructable to boot, can't praise this enough - thanks for the inspiration, Carl

Thinkenstein (author)carlpeb2011-01-11

Reed instruments were abound the last ones I got to exploring, too. Maybe some of that had to do with the cost of them, which I found relatively expensive. Percussion is cheap. You can even find interesting things to bang on in the trash.

I'm glad you are getting enthused by the tootophone. Someday, I hope to hear a tootophone orchestra with different variations of the instrument creating different voices. We just need more players.

carlpeb (author)Thinkenstein2011-01-11

I've also been greatly inspired by Bart Hopkin and Denis Havlena's various instruments - one thing I was wondering about the tootophone - is there any relationship between the length of tube and tonal range, or is it entirely down to the reed? I'm interested in lower ranges - would a longer tube inhibit range?

Have you tried making a double reed from the rubber material - I shall be trying a lot of things out in the near future! Have you come across Fran Holland's balloon organ, it's fantastic - I've borrowed the same principle on a number of instruments (although I'm not nearly organised enough to get an organ together)

As I live in UK it rather rules me out from your orchestra, but if I was local, you could definitely count me in! Maybe it could make a good international project on the web.

Nice to chat,



Thinkenstein (author)carlpeb2011-01-11

Especially with the rubber reeds, body extensions give it a deeper voice. With the addition of body sections, I sometimes get changes in behavior of the reed. When I do a sliding scale, I start to get steps, or skips in the scale where note segments are missing. I still haven't figured out why, or how to eliminate them. An empty silicone rubber cartridge as an extension makes a nice resonant bass. Cut the conical tip of the cartridge in the right location to make a tight-fitting area to plug in the end of the tootophone.

I have been unsuccessful making double reeds. However I do sometimes make two tootophone mouthpieces side by side so I can play both at the same time. The duet effect can be nice.

The balance of reed material, curve sanded into the mouthpiece, and the sort of body extension used all affect the sound.
