Playing the saw brought back many pleasant memories of my own high school physics teacher back in the early 70s. I agree that having the handle for the tip of the saw is certainly easier on the hand! We used a violin bow but making one's own bow I think (as a music teacher) is the better way to go. Great stuff!
I would guess that I've been at this longer than you have (just finished my 40th year) but I hope that you can use what I've learned and surpass me. Thanks for your comment!
@@YeanyScienceHello, I really could need your help. What material is your plate and thixkness, I used 70cm2 aluminum 3mm thick and I cannot make it swing nicely. I am using a violin bow with rosin but will try to build one according to your design.
This is the most interesting video I’ve seen in a looooong time. I’m going to build some of those plates and impress the heck out of my grandchildren. Thank you !
I love this! I have a program called The Science of Sound that I bring to schools. I'm definitely including some of Chladni plate demos! Thank you for this great video!
When Mr. Yeany started yelling at the Chladni plates, I almost had to stop and rethink my life. I'm watching a grown man yell different pitches into a metal plate with sand on it all in the name of science. But I still love it! Keep up the great work Mr. Yeany!
one of the few scientists doing useful things by YELLING at the equipment. way to manage your supplies! EDIT: also props for using the original meaning of 'fast' before war kind of changed it to mean quick.
Fabulous. I read a section in an old encyclopaedia from about 1900. It explained how to make a “sound picture.” You had to take a metal saucepan, stretch a skin across the top, sprinkle sand on the top and blow down the handle making different noises and record what patterns were made by the sand. I always wanted to do that, but I thought mum might not like it. I still have the book.
Your method of making a bow is simple and very effective. I wish I had thought of that earlier. I had made one by buying the string from a music store, then using a bar clamp as the bow, but the strings were not uniform and started fraying. I'm going to have to make one for next school year's physics class. Thank you for sharing.
I've been impressed with these, I compared it to a regular bow and found it works just as well but it may need rosin a bit more often. I'm not sure if the dowel needs to be bent quite as much as what I have. Good luck with the build.
A neat demo you can do with the violin rosin is to rub a liberal amount on your fingers and thumb (if a piece chips or off, crush it between your fingers and rub it between your index finger and thumb). Grab a metal rod or pipe (copper works great, but galvanized is ver difficult) in the middle with your unrosinned hand. With the rosinned hand, pinch the pipe firmly between your thumb and fingers and slide your hand down the pipe. It should start singing and repetitive stroking will make it sing louder. The waves produced are longitudinal waves and the ends can be seen vibrating by suspending a small washer from the ceiling, and touching the end of the pipe to the washer...the washer will shoot off quickly from the end of the pipe. Making the pipes sing is also fun to do at the hardware stores...you get a lot of puzzled looks. :)
LOL, I do have one metal bar that works but hadn't thought to try it with others and would I'd like to add a variety to my collection. I will try that at the hardware store before making my selections. Thanks Dwight
Honestly, thank you for this video. I was planning on buying a violin or cello bow to use on my guitar but it would destroy it in minutes. I'm glad you uploaded this because now I don't have to buy a real one.
been trying to do overtone singing lately, it's crazy how these work lol. some theory i heard about frictives being composed of ~5 + vowel or so overtones lol kind of interesting, like I've been using yaw, way (aioueyiou) to try and exchnge chest resonant cavity note with nasal cavity note through the back of the "hyeangiouweay" throat / intermediate part, it's like the sound goes to my nose / ears then out and back to my chest / diaphram note and my tonsil area / mouth chase the note through to my ear's / jaw + head (and you can tune in to single teeth if you find the right oscilation pattern lol. But this is great visualizer for what's happeneing. I'm excited to try different particulates to try and model the cycles that are happening. My mom has colored sand, I told her about your method and she made some of her uglier (gawdy and blech colored lol) sand a tolerable green haha.
Well done and amazing, as always! I was surprised that you could use the slippery nylon line for the bow. I know you applied rosin, but I did not think rosin would have adhered to smooth nylon.
Thanks Slater, the nylon works great, I compared it to a real bow and found it worked just as well, however, I did find that rosin may need to be applied more often.
I have just made my own "bow", it is more like a long wand though (Same length as standard bow) not too bad as it goes. I just used a thin wooden rod with electrical tape run tightly lengthways (Don't wrap it around, except at the ends). I am going to buy a proper bow but to be able to have a go with just a saw and stuff you may have lying around is awesome fun :D
Bruce, Hi thank's for your reply. My comment was only to give people a shortcut to have a little play with very little effort. Please try it for yourself (Simple bow made of a thinish rod of wood coated in lengththways stretched electrical tape) and let me know what you think, you may be surprised by the results. Your video did inspire me to invest time into the saw :D I am still working on muscle memory but am improving in leaps and bounds.
I want to know where to by the thing that vibrates and how to adjust the frequency. I am a physics teacher in India . I want to show this to my students. Thank you
I have a Chladni plate and a subwoofer. I've been experimenting, however I'm not getting such clear patterns. With a similar setting, how can I connect the subwoofer?
Rosin helps to make the bow string sticky. it's the stickiness that grab the string on a violin, or in this case the edge of the plate and then let go, grab and let go, grab and let go on and on for a few hundred times per second. This is what is setting up the vibrations in plate or in violin strings
Yes iam in a bedsit room with the volume up on my pc while i was doing the washing up - reminded me of the sound effects from the Poltergeist film.! ( - ;
Okay so when you rub the bow across the metal plate the sand rests on the nodes because that's where the sound waves are less frequent? So does that mean we're looking at the actual vibrations of the sound? So we could actually physically look at music with that?
I like to think of it that way but we're not quite seeing the sound itself but it is still a beautiful result to it . What we have is the reaction of the material to sound wave energy and the patterns change as the intensity and pitch change.
A few of them were cut from the sheet metal of an old refrigerator door. Some hardware stores sell sheet metal in various sizes or check for a local metal fabricator, also auto supply stores sell sheet metal for auto body repair
The sounds and the patterns that form are almost alien in nature. Made me think of an alien race that communicates with chirps with frequencies being phonemes then perhaps their writing would look like the chladni patterns on the plates.
Tidbit I found lecture 6/chapter 6 of John Tyndall's book on "Sound" rather wondrous the sensitivities of flames and streams of water to the most faint sounds. And observations of gas lamps at train stations and theaters or a house sparrow's chirrup from 30 yards away ... lots of fun facts ... or things inspiring to know. It's also readable on Google books as well as Internet Archive. archive.org/details/soundacourseeig01tyndgoog/page/n237/mode/1up

Thanks, I have enjoyed making them, unfortunately, I am doing these on my own with a point shoot camera, no budget, no help and not enough time to learn the skills that would make them better. Hopefully people can get past the amateur look that they have.
I love all your videos, all experiments. U r cool man

thanks Mark, I will try
I love watching these, Mr. Yeaney. Keep it up.
Thanks Elliott, nice to hear from you. We miss having any Facklers in school!
I needed to know how to make that bow so badly thank you! I have what I need for it here at home. Now I'm off to buy a saw and try it out.
That is awesome! I'm gonna make some of those. Thanks for sharing.

Really love your videos. I am a physics student and it's very nice on how interesting science can be.
Incredible, thanks.
Awesome! thank you for this...
Excellent video Bruce!
Very entertaining and informative, might give these things a go myself :)
Thanks,I hope you do!
Cool I have been learning too!
This is so cool!
For some strange reason, the sound made me think of the Devil went down to Georgia and Johnny rosins up his bow. You gave me an earworm.
Honestly, thank you for this video. I was planning on buying a violin or cello bow to use on my guitar but it would destroy it in minutes. I'm glad you uploaded this because now I don't have to buy a real one.
glad it could help

My mom has colored sand, I told her about your method and she made some of her uglier (gawdy and blech colored lol) sand a tolerable green haha.
its cool cause the screw "re-centers" the vibration. thats cool. im going to try it to annoy my neighbors! thanks!
thank Bruce for sharing us excellent experiment. May I know the thickness of the plate? I have tried 1.5mm thickness. It seems not work.
Well done and amazing, as always! I was surprised that you could use the slippery nylon line for the bow. I know you applied rosin, but I did not think rosin would have adhered to smooth nylon.

Oh and I totally get harmonics lol :)
Hi Darren, I will give it a try if there is an easier way and more people will try it, then I'm all for it
your a genius Bruce :D
That sound must be number one on the ghost top 100
1:06 when you like your job
You should now do something explaining sound deadening materials. You could apply those materials to your plates and see the difference.
Thanks for this teaching! I’m helping my niece with a science project and was wondering what gauge metal plate are you using? Thanks so much!
Respect 🤝
i wish i had you for physics
extremely cool
I want to know where to by the thing that vibrates and how to adjust the frequency.
I am a physics teacher in India . I want to show this to my students.
Thank you
Hello Bruce, love the video:)
What driver are you using under your chladni plate? Thank you
it is a homemade driver made from a audio speaker, 8 inch
I have a Chladni plate and a subwoofer. I've been experimenting, however I'm not getting such clear patterns. With a similar setting, how can I connect the subwoofer?
Nice sir
Magnifico
The yelling part killed me
How you made the bow?? Please give a bow made tutorial
Hell yeah! clubbed thumbs!
Anyone wanna audition for my band? We're about to take the world by saw. Our next record is gonna be 🔥🔥🔥🔥
Great video as always but I have one concern. Why did you apply rosin to the bow?
Rosin helps to make the bow string sticky. it's the stickiness that grab the string on a violin, or in this case the edge of the plate and then let go, grab and let go, grab and let go on and on for a few hundred times per second. This is what is setting up the vibrations in plate or in violin strings
When I watch this video on my phone, my dogs going crazy. Did dog response to certain frequency?
I wasn't paying attention and the sound of the saw scared the crap out of me
Yes iam in a bedsit room with the volume up on my pc while i was doing the washing up - reminded me of the sound effects from the Poltergeist film.! ( - ;
Okay so when you rub the bow across the metal plate the sand rests on the nodes because that's where the sound waves are less frequent? So does that mean we're looking at the actual vibrations of the sound? So we could actually physically look at music with that?

Thank you for this vedio
But I have question what is the name of the material you put on the board is it salt ?
sand or salt, either will work
Thank you 💟😍😍
Now I know where they got the sound for that voice in Don't Starve Together
LOL, I always thought the trick to that was making the noise with your mouth....
Awsome
Exactly what metal is this? What other material can I use to try this?
it is a thin steel plate, I cut the pieces out of an old metal cabinet for an electric appliance.
12:45 for those who watched
12:55 for those who didn't
Will this bow work on other instruments
I haven't tried it on other instruments but I've tried a violin bow on these pieces and it is about the same
Where did you get the metal plate???
A few of them were cut from the sheet metal of an old refrigerator door. Some hardware stores sell sheet metal in various sizes or check for a local metal fabricator, also auto supply stores sell sheet metal for auto body repair
what is this thing you're applying on the string ???
It's rosin, which is basically hardened pine tree sap which adds friction. Costs a couple of bucks on Amazon or your local music store.
It is violin rosin, musicians apply it to violin and cello bows to make them sticky. I think real bows use horse hair, I find this works just as well.
Some of those plates had annoying sounds but they all had amazing patterns forming.
LOL, you should be there when I record them, it's a lot louder!
That is physics for my taste.
Where can I purchase a chladni plate?
do a search online and you will find several offers
like maestro
The sounds and the patterns that form are almost alien in nature. Made me think of an alien race that communicates with chirps with frequencies being phonemes then perhaps their writing would look like the chladni patterns on the plates.
Dear sir, What is the thickness of the plate? Tried with a 0.3 mm thick steel plate, but it didn't work.
that is thinner than what I used, not sure what the gauge is, but I would guess it's at least twice that, I will check and try to find out
When you find a good reason to yell at a bucket
the yelling at the bucket was something I discovered in the middle of making the video, find that happens to me a lot

Where are you gonna hang your play button when you reach 100K?
I hope to hang it in my classroom, show it on youtube and thank the subscribers that thought enough to get me there.

Sounds like a Theremin
Do you know there is a festival dedicated to playing music on saws? ruclips.net/video/eON-p4afeTkF/видео.html
Come play your saw and learn more about saw playing!
that is awesome, however, I have no musical talent whatsoever
somebody please save that whale
Thank you. I love your videos but the unadjusted version was just unberable :D
I went back and tried it with headphones, my ears still hurt
Minecraft cave noises be like
Also if you really get advanced with these vibrations you can make any image...realistic....like anyone's face so on

Rubbi g bow on plate sound like horror movie music
this is fun but i would expect a tad better editing from someone interested in technics ‘^^
Thanks, I have enjoyed making them, unfortunately, I am doing these on my own with a point shoot camera, no budget, no help and not enough time to learn the skills that would make them better. Hopefully people can get past the amateur look that they have.
Thats the most annoying sound in the world. You have to give it that sir.
Funny how this is all about sound so I have to say this,,,professor chladni,,,you are mispronouncing chladni
