Chladni Plates
Ойын-сауық
Four centrally mounted brass plates are driven into various resonant states with a violin bow. Sand sprinkled on the plates helps to visualize the nodes and antinodes for each state. Pressing a fingernail against the edge of the plate imposes a boundary condition (as does the location of the bow, for certain plates).
There are dozens of continuity errors and other technical mistakes-sorry about that.

my cat is obsessed with this video and comes every time i play it. im not sure why but he’s a huge fan.
I love how he wears eye-protection. I would have chosen the ear-protection XD
This is amazing. Thanks for sharing with us.
Is it possible to get all these sounds downloadable for use as a ringtone?

Uh, what year are we in? Fellow time traveler here.
I love the Zen puff at the end
we haven't tried that. maybe the sand would tumble down the incline instead of collecting in the nodes?
That's f***ing ART! I love it
Its gotta be +90dbA Ear plugs! Nails on a blackboard? Fascinating how the rhythm of the bow changes the modulation of the frequency with certain metal shapes and grains of salt sugar on the mental plates surface.
Hell yeah. So if I walk up to an ancient portal and say the magic word, it could reveal its secrets to me with a liberal dusting of powder. Story of my life.

this is amazing
Heard about these in Thomas Mann's Doctor Faustus . Glad I read
pretty impressive
Amazing
Like a kaleidoscope....
Different sound provides different particle order or is it the same if it's done again? I'm reading the music theory for computer musicians and there I saw they mentioned this experiment which I've never heard of before. But is it harmonic music or just noise?

I would assume it's mostly harmonic, because you can hear discrete fundamental tones.
Amazing!

Thanks!
how particle size affects results? why don't you use particles of different sizes?
My mind is blown!
its art!!!!
Any scientific research on Cymatics is available at your lab because I very much interested in it
I wonder if the use of interlocking blocks in intricate patterns in ancient structures like Machu Picchu work in a similar way. The blocks create a system of tension and compression forces that can help to distribute and dissipate energy throughout the structure, reducing the risk of collapse from earthquakes. While the physics of Chladni patterns and seismic waves are different, the underlying principles of energy distribution and resonance seem similar to me. I wonder what frequencies earthquakes tend to be and what patterns in 3D are most stable under those conditions

I would imagine earthquakes would have a very complex frequency that might be hard to pin down lol. Typically the strength of a pyramid shape structure is only strongest because a pyramid takes up a very low volume and thus resists the effects of gravity and collapse more than another shape. Very interesting idea you have though, it's always food for thought
is there any way a high school student could create something relative to this?
what is the thickness of the plates? are they pure brass, or some kind of alloy? would carbon steel work as well? do you need a metal or foam/rubber washer between the screw and the plates? does the distance between the plate and the wooden mount matter? I WANT TO MAKE SOME AND I JUST HAVE SO MANY QUESTIONS!!!!

can u try different material for the plate?
That’s is amazing 😉 love 💖 physics
So these are Tanavast's tones, uh?
fascinating
I think this video probably damaged my ears but it was totally worth it
I want to do it at home. What do I need?
I believe the sand wont fall down!! could you try that*?
The violin string is all good but what about using speakers and more complex sounds?
what happens if you tilt the plates?
this made me grind my teeth into dust
The sand falls off?
so the music, depending on the vibes, can certainly give "shape" to the matter. it probably influx in the developing of "one shape" or the other, in biology or cell terms (?) may have an influence for example in the creation of one form of cells or other? how much? this forms (from vibes) always reminds me the different cells in the microscope. anyone knows any research of that?

Ofcourse you are right... Music can give shapes to matter which means, different frequencys of sound can alter cells. This gives much more complex thoughts about solfeggio frequencys and our health
what would happen with water?
Sounds awful, but looks beautiful :)
This is literally how they make horror movie sfx. Not even kidding
you got a suitable username for yourself
IF you record those sounds and attach a speaker to the bottom of the plates and replay the sounds WILL THEY form the same patterns ?

Good question! My initial guess is that it could work, though one may need a dangerous amount of sound pressure from the speaker to get the sand to move the same way that the bow can. An easier-and more common-method is to mount the plate on a mechanical transducer and drive it with a signal generator.
And theres me who puts salt on my dinner and a bow on a fiddle ....
Trippy
okay, this is obviously a wizard.
Wow
nice :D
Are there any equations describing those shapes?

Thank you so much for your response. Greetings from Chile where I hope to make some chladni plates. You are sure they are brass? The color looks more grey, perhaps then a nickel silver brass alloy?

I know this is a 9 year old comment. However I absolutely agree. I think the patterns are actually an alphabet of sorts. It's already known sound is universal,and almost anything can produce sound. Our scientist tell us math is universal. I believe this for is more universal than math is.
OMG! my martini glass broke! LOL
i feel bad for that bow lol
Does this remind anyone else of Prince of Persia? :D

Richard Watkins invokes this phenomenon as an example of how biological information/potential/memories might be stored as "songs" in resonating bio-energetic fields: kzread.info/dash/bejne/oIub3LmSpJjJaJs.html He gives this example starting around 13:42.
