Sound Visualizer & Chladni Patterns Formed on a Plastic Bucket // Homemade Science with Bruce Yeany

- The Sound Visualizer and the Chladni Bucket are used to show how vibrations from sound waves are able to create some very beautiful patterns using a few simple pieces of equipment. As compression waves from sound hit a surface it may cause standing waves to form. In the first case, a mirror attached to the surface has a laser aimed at it, the reflected beam is then aimed at a wall and a pattern will form due to the way the surface deforms due to the standing wave. Changing the pitch will cause the surface to distort in different ways causing new patterns to be seen. As combinations of tones are played at the same time, more complex patterns will be formed.
The traditional Chladni Plates are solid metal plates that were originally caused to resonant using a violin bow. Sand or some type of powder is commonly used to show the patterns formed by settling into the areas of little energy (nodes) versus being removed from areas of high energy (antinodes). The more advanced version can use a tone generator and vibrator to excite the metal plates and produce more intricate patterns. In this case, I am producing the same types or standing waves on a trash bag that has been stretched across the top of a 5 gallon bucket. The simplest way to resonant the surface is to simply shout at it at various pitches.
Teachers in hallway:
*Teacher 1*- Is Bruce Yodeling in his classroom?!?
*Teacher 2*- No, He's just screaming at sand.
*Teacher 1*-Oh ok, that makes more sense.
LOL, you pretty much nailed it, the teachers around me are pretty good sports and have accepted me doing things like this
boys will be boys when playing in a sand box.
or screaming at it ;)
boabab95 HAHAHAHA classic....they are probably used to it 🤪
I feel like this should be mandatory for all physics teachers at some point in the year. For me, it was bowling ball week while learning about Newton's laws. It didn't help that we were on the second floor.
I've been looking for DIY Chladni plates for hours on youtube.. your bucket+trash bag is the best all night!
Now I know what my neighbour is doing, he's just creating sound with sand. I thought he was calling out to me.
0:30 That moment when you can't stop playing with the new toy.

- Let's get starteeeeeed!
- All right.
....
*This thing is so funny*
- Let's go.
😂
It just fascinates the heck out of me how the tones create those consistent visual patterns.
And if you look at art created by ayahuasca shamans you'll find the same patterns. Super cool.
Acoustic waves interacting. Imagine the effects of EM radiation or even gravitational wave interactions on relevant matter :)
They're so pretty as well
Bruce you're awesome!
this is just amazing to look at, great video
Wow, I definitely need to built one of this ! It's awesome !
Awesome videos Mr. Yeany. Wish I had you as a science teacher. I hope your students appreciate you.
Watched loads of your vids now, Everything I want to have go at 😁. Its great to have these demonstration vids to learn from. Epic teaching style.
Love this video!
Thank You Bruce!
Very inspiring and very nice to use common items to create the experiments!
That was amazing. I loved watching that. I feel like making my own now and doing a lot of experiments. I can already think of a lot of applications for it.
love your simple and informative experiments. my grandfather who was a math and science teacher would have loved them as well and it's like watching his experiments again. thank your and keep it going
So... freaking... amazing!!!!
Bruce thanks for this video I always love your videos you're a amazing teacher
so simple yet so education and fun. your time and effort are very appreciated. thank you thank you thank you
I love how simple your devices are
This was such a great example of clear, practical scientific demonstration- thank you for your excellent work Mr Bruce!! 💪🏼
Such a great teacher! Thanks for the projects. I can make them in my school too! A grand salute to you!
Thank you, Bruce!
Mr Bruce, great and amazing video and its very very interesting because I like music and physics. thank you very much for this.
Best videos EVER! I love that these are so simple and so amazing. thank you so much for making these!!!!
You the man Bruce! Your example is the best 💣
Hey Bruce, I've been watching your videos for quite a few years for my own entertainment. Now, I'm rewatching for ideas to amaze my little children and get them thinking about science.
good luck, there should enough ideas to keep you busy for a while
The salt visuals really amazed me. I had no idea. Amazing!
I love you! Thank you so much for making this in such a simple way!
Mr Bruce, you are so inspiring 👏🏻👏🏻👏🏻 I am a physics teacher from Turkey, I love watching your videos, thanks for sharing 🙋🏼
Hello Guzin, thank you, nice to hear from someone in Turkey
@@YeanyScience hello i tried to make it but it's not working like that, is it a special laser or mirror ?
@@YeanyScience , i am not sure i understand why would a mirror-reflected light be a pattern? 9:57
Since the mirror is a plane, no matter the vibration underneath, shouldn't the reflected light form just a single point on the wall at a time? Why is the pattern a closed loop?
Such an inventive experiment. Thank you so much!
Best and simplest video.Great job!
This is amazing, I've doodled with lasers before, but I built my things with rotating mirrors in LEGO :D I will definitely have to do this to have as a music visualizer here at home! Super neat project :O And so simple as well, nuts! Cheers :)
Thank you Mr. Yeany for making this video! My four year old daughter and I made the laser sound visualizer and it was awesome! Will be using this idea for many avenues including vision board parties and in a preschool classroom teaching that words do have power!
...We also made the sand pendulum!
Thanks again for the simple instruction, but very detailed and easy to understand concepts!
Good stuff! Thank you for taking time to share
Amazing experiment! Even if one sucks in the science department, one cannot say this isn't awesome! Thanks for sharing, Bruce!
simple and enjoyable to watch, please create more videos.
This is awesome! I'm going to try this in my classroom.
Absolutely awesome.
Very good this demonstration, thank you!
Thank you Mr Bruce you always make my brain so happy! :-)
Another great educational video, Thanks!
That was great thank you. Love the enthusiasm 👍
What an inspiring educator.
Holy shit that's amazing
Omg this is awesome, I wanna build this
Bruce - Great job on this video! Love the screaming Chladni patterns.
Thanks Steve, I had a lot of fun with this one, ( well, that's actually true with all of these) the shots were pretty much first take videos as I was experimenting with the bucket, so the next step is to we see how we can improve it on it.
Wow, I can scarce believe how amazing this was to watch, I want to teach Year 3 sound just for doing this damn lesson now... it would blow their minds just like it's just blown mine!
i love you
this is awesomely amazing and wonderful!
thank you
please never stop making these awesome videos
Insane! That is so cool!
Omg you getting me so much ideas for my class. Awesome
Simply amazing!
Nice! Keep it up!
FANTASTIC, VERY NICE.........!!!!!
Never get tired of videos visualize the invisible :)
You sir are cool! I enjoy these vids very much!
This is awesome! Thank you!!
I'm so glad to see you doing this in the classroom. I wish I would have had you as a physics teacher!! I had to go get an engineering degree to realize how much I love vibrations and acoustics. I'm currently building a speaker box with this concept built in. The issue i'm having, of course, is that the rubber membrane is acting as a passive radiator and making a sound of its own, throwing off the tuning of the box.
Great content to get people interested in vibrations!
thanks, not sure what to recommend for you speaker but keep trying, good luck with it
This is fantastic!
This is phenomenal
Thank you. I will try once again
Love this video! Gonna give it a try
You make my most favorite videos. You turn complex science into fun that inspires all❤
thank you Jami
Always a delight to click on a random video because of the thumbnail/title and it turns out to be a Bruce Yeany vid!
Sounds like you had a lot of fun making this video!
ma shaa Allah ..thats amazing
excellent vid. and very impressive singing!
Very very cool. Awesome channel.
really awesome demo thanks
well done explanation of one of my favorite topics
Excellent vidéo thanks so much ❤
Mr. Yeany, I don't think you could know what a difference this video has made for me. With my infinite thanks.
glad you liked it
Amazing! You are my hero!
awesome, you are a great teacher
I gotta say, the digital clock at 1:40 in the top right looks so mesmerising when shot with your camera.
Its really Great experiment .. you are Good Teacher .. thank u.
Loved your video
Ahhh it was the perfect opportunity to play the Close Encounters of the Third Kind theme :D
Good lord I love your videos... This is so creative and interesting!
thank you
I used to have the same keyboard like the one you use when I was a kid. It has the best pre-recorded beats ;D
wonderful explanation
We built the Chladni plates from your other video. We followed it to a T and it just would not form uniform shapes, just random blobs and it wouldn't even work on most frequencies. Over and over we tweaked it and adjusted changing plates, materials, speakers, volume, but, we just couldn't get salt sugar or sand to create those cool shapes or designs. worked on it for about 7 hours. That pushed our time limit to the edge, so we quickly found and built this one and it too, didn't work well. I tightened and loosened the balloon, moved the laser closer/further, vocalized closer/further from the plastic jar but, we couldn't get those crazy and cool shapes from different vocalizations. We even tried different sized balloons and different brands of balloons too. Nothing. Spent way too long tinkering with it. Then while taking a much needed break, my wife put a metal can on the bottom side of the wood and we tried it again and although it worked better, with a few cool lines, it only works a bit and only on certain vocal frequencies! Super frustrated with this project/experiment. Not sure WTH we did wrong or didn't do right but, after 9 hours with this one and 7 hours with the other one, I'm flat out exhausted. Scientifically, emotionally and physically. HA! You MUST''VE tweaked it some in some way to get it to respond so well. I wish I knew what you did to make it work so well, because it was very responsive/reactive to your vocalizations but, not ours. He had to take it in to school today anyway because there was no time left. Im guessing there were some tweaks that you must've made and I wish you would have gave some suggestions that might have helped to get better response.
Very nice sound
Inspiring stuff good sir .....
Am reminded of the wonderful Prof. Julius Sumner Miller showing beautifully geometric patterns achieved on a steel plate with a violin bow .....
Thank you , Prof. JS Miller has been a big inspiration in my teaching
Thanks, just found this. Now I know how to get patterns for my artwork! :o)
great video!!
your singing made my day
superb video
Oh wow! Great!
Fantastisch, danke!
Sir, you are an inspiration. Greetings from a couple of artists in Portugal ;)
