Thats cool. Its hitting all the high frequency mode shapes of the plate, and the salt is falling into the standing wave nodes Run a high frequency modal analysis on any FEA software and you see the same thing, but I've never seen it visualized like this before.

The machine is called a "wave generator." It simply creates an electric signal output that goes to a speaker. the speaker has a rod attached to its front, and the flat metal square is attached to the rod. At certain frequencies, the plate resonates, and flexes in a "standing wave" (google that).

i've seen many responses that suggest the sand is moving as a direct result of the sound. this is not the case. The sound is used as a harmonic force input to the plate. this input excites the natural frequencies of the plate and it resonates in a mode shape. the sand is simply gathering in the nodes of the waveform on the plate.

What amazes me about this experiment is how the sand grains just instantly shift seamlessly to another shape or unique pattern perfectly. There's something very important about this idea. I can't put my finger on it yet. Being able to see sound at its frequency of vibrations, much like what hallucinogens do to a psychedelic tripper, except sound is also in the form of vibrant color. Cymascope would probably be more relevant there.

think of a standing wave on a string. if there are particles on the string, they will roll into the valleys of the wave. when the wave reverses (180 degrees later) they will start rolling the other way. the steady state result is the particle gather on the nodes, constantly rolling back and forth small distances, always falling downhill.

This is simple. The vibration of the plate vibrates differently in different spots. The distance from the center is the reason it makes the powder alike on the sides. Certain frequencies make it vibrate certain ways which is why it makes a "perfect picture".

The salt is being poured on to a special machine that oscillates the square plate vertically (quickly moves up and down), and can be set to a wide range of frequencies (causing the sound you hear in the video). It's a really cool experiment in a physics-lab.

In science sand particles form a certain pattern when activated by sound. Low frequency creates plain geometrical shapes. The higher frequency is, the more rich and exquisite pattern it takes. The interesting detail is when frequency changes before it becomes a solid shape, it creates chaos..In life- one has to go through an emotional turbulance, before things calm down. By changing your thought process, you change your life (same concept as the sand experiment)..

You can't see it because it's moving so fast, but what's happening is that the plate is being vibrated, and the plate is moving like a wave. In some parts of the plate, different bits of the wave hit each other and cancel each other out. In other places, they reinforce each other. In the places where they cancel each other out (destructive interference), that means that the plate isn't vibrating there. So the sand just sits there and isn't moved. As the frequency changes, the patterns change.

This is how Tibetan monks and others began to take the universe apart to study it. They had no power so they used bowls, which are called "singing bowls".... When they "ring" < they are actually at their resonant frequency... these different frequencies generate the geometric patterns on the Chladni Plate......... peace

the sandy areas represent the nodal lines of the waves where destructive interference is happening, thus no movement of the plate in these areas

This is amazing. Just goes to show.

it's like catching a quick, inside glimpse into the workings of Nature.

Imagine you have a long rope fixed to a wall. If you send a wave down that rope (by flicking), when it hits the wall, it will come back to you, except its bump has turned upside down. Now imagine that you send another wave down the rope before the first one has made it back to you. When the two waves meet, one bump is up, one bump is down, and they are both the same size. They will cancel each other out for a moment. That is what is happening with the plate, but adding another dimension!

@barryfarrimond It's not so much that the waves stabilise. It's what's known as a standing wave, if a wave propogates and hits a wall, end of a beam, side of a plate etc. It is immediately reflected, causing supportive/destructive superposition. The wave effectively stops propogating(though it still is) and appears to stand still and oscillate in position.

@AxemastaGAMING I think it's the other way around. The nodes are the positions where the sand moves to, since those are the most stable positions.

@Aeway100 The nodes are where the salt sticks, i.e. the parts which are not moving. The antinodes are not visible, of course.

it is all about acoustics. If you didn't study acoustics or wave physics, it is hard to understand this phenomena.

It's not just a good theory, it's directly linked to the phenomenon of higher consciousness and intelligence that has been known only to few occult socieities on earth. Frequency, highly sophisticated sound and waves is the key to pretty much everything.

holy crap my ears almost imploded from the sound...cool stuff

cant you just see the beauty of it?

THAT'S INSANE!!! This video blows my mind. It made my dog howl like crazy too for some reason. Great video though...really got my gears a grindin.

You dont need a second pressure wave the reflection of the first wave at a fixed nodal point(the end) is enough to create a standing wave.

Some of those shapes where amazing! Also... It's symetrical OMG... and last DID YOU SEE THOSE PERFECT SQUARES AT ONE POINT?

@AxemastaGAMING I think we have the same understanding of what's going on, but I think we might have a communication error here. :S The anti-nodes are the points where the sand moves away from, since those are the points that vibrate the most, while the nodes are the points where the sand moves to, since those do not have 0 amplitude vibration.

@TheRealVerbz You think a bunch of guys are using resonance to break cornstalks? Holy shit, they're even better organized than I had imagined!

Huh, radial and angular nodes, quantized energy levels. This would be a great way to show a visual representation of where orbitals come from to Gen. Chem students.

I think there is deeper knowledge to be had here. These aren't just pretty patterns on a plate.

Cosmos = Resonance = Energy

@nextbest47 82 seconds in we all started rolling around in a geometric shape

Actually, my mother did a rain dance once when she was a kid, but then a tornado hit. So no, I'm not inclined to believe that rain dancing is %100 effective.

So awesome. Think about how certain songs make you feel good. What if that's it. Certain frequencies make you body do certain things. So awesome.

@steveb391 It is possible, but the thing is, the energy needed to move said crops would be very high. It could very well be a high sound producing crop circles, but it would likely be loud enough to leave behind some evidence. Plus crop circles are easy to make with a stick and a string. Plus the images aren't particular to resonance images. Plus the images only tend to cover part of the feild, not the entire thing. This would be akin to the image in the video only using 10% of the plate.

@Zee96969696 The shape of the object itself has a lot to do with it... when anything vibrates to a pressure wave (sound), it does so in those symmetrical 'ripples', which originate from the center because of how it's attached to what I'm guessing is the source. Ever seen a shockwave?? It's like that. When the sound goes higher, the WAVELENGTH of the sound is shorter, and so there are more nodes and antinodes created on the surface of the object.

You don't travel on sound waves, you vibrate the craft to a specific frequency, like to the frequency of green light. vibrating at that frequency will give the craft unusual properties, in fact it would glow or emit that spectrum of light. like a flying saucer perhaps?.

ya that "rotating" part of a wave is the node.

Ow... The sound hurt, but it was incredibly nifty to watch the salt move. :D

@tudoralexe No... it's the proof that each sound frequencie has diferent shapes.

shld be one. creates nodes cause the waves are.."in" the plate. so when it reaches the end of the plate it reflects back. creating the nodes. i believe

when i first saw the symbols made by the studies they reminded me of a man who used to draw things on the sidewalks of cross roads . . . he carried a bugle under his arm . . .

Vibrations really hold everything together. There's always a high pitch frequency, if you meditate you can hear it.

What's with this hatred being expressed on a video that is showing us the beauty and love of the universe? Take a lesson from these images and be more harmonious.

I would like to see a simple tiered scaffold with multiple membrane levels (perhaps a wide taught stretched cellophane perhaps). if you do multiple levels a couple inches apart, framing in a square you would be able to get a fully "3d" idea of how it looks. (in 2D slices).... I guess if you did a white wire frame you could put a couple drops of dye into the salt in a blender. say against a white background the same color as the frame. the frame will "disappear" and the salt will have vivid contrast to the background. Anyways dude I woke my ol lady up. thanks. but cool stuff really. .

this is the way the ovni´s fly,,that´s the same sound. :) Very nice.

Just realized I was being dense. The pattern is banded because it is just a 'vertical' slice of the interference pattern. Although, I'm still curious if we could measure the waves after they left the slit (rather than just taking a vertical slice) without collapsing the probability. I'm probably not making sense, sleep now.

well.. i was asuming that it went to highpitch for me to hear. obviously it didnt stop because it was still going (unless you suffer from blindness then your answer is ok).

My headphones are clicking from this high.

I know. I was illustrating it more clearly.

there doesn't doesn't have to be a WHO if there is a WHAT. Energy can and could be the creator of everything. Energy can be created by an explosion which, often times, happens to matter which could have just always BEEN here!

from the description i'm guessing the sand is outlining the 'destructive interference' of the sound waves =]

at about 0:57 i stopped hearing the sound due to inner ear damage i suffered when i was about 4. a lot easier to see when you don't have to squint in pain from annoying sound waves. (my speakers are broken and wont turn down.)

I like the X pattern at 0:45 but theyre all cool

...that's the movement of the hairs in your eardrums, and tension from your shoulders.

me too!!! ran away terrified from the room.

@happybuddyperson Uh... no. The REAL reason this works (without the mystical bullshit) is simply that in any standing wave on the surface of a solid like this one, there are nodes and antinodes. The nodes are places of absolute rest - they are stabilized by the opposing motion of the two adjacent antinodes - so it doesn't move. The salt rests in these places because it's simply forced off of the other places by the motion.

lovely shapes!! i want to grab the first pencil i see and start draw those!

Ah, we had that experiment shown in physics lesson at uni. awesome stuff O_O

were tachyons proven to exist, what you are implying would be almost plausible. The only problem is getting it to travel, and maintaining the core stability of A: the vessel itself, and B: its contents (ie humans).

Holy shit, I was wearing headphones at high volume when I stumbled this!

nice I think there alot of things became more clearer before seeing this vedio

This is a great video. What I would really like to see are the patterns of these frequencies in Hz: 174, 285, 396, 417, 432, 528, 639, 741, 852, and 963. Which I'm sure are shown on here at some point, but it would be great to see a video for the Solfeggio Scale itself as well as 432 Hz.

cymatics, its all about resonance fields

To quote Epicurus: Is God willing to prevent evil, but not able? Then He is not omnipotent. Is He able, but not willing? Then He is malevolent. Is He both able and willing? Then whence cometh evil? Is He neither able nor willing? Then why call Him God?

I believe that this phenomenon when utilized with a craft, at a specific frequency, could be used for travel, perhaps even through space. This could be used as a loophole to travel intersterally, almost instantly while still obeying the laws of physics.

for anyone who watches one piece: the best opponent to crocodile would be that annoying noise

not bad for compression format at all

So sound waves do that in 3D all the time then, is that right? Cool experiment!

sweet, I had to turn off the sound 1/3 of the way through though.

wow hats a good theory i haven't heard that one and it makes sense

i love this song

imagine the holes those high pitches are making in your ears! yeouch. LMAO xD Love this stuff. Those patterns are crazy.

now there's a thought

You should check those patterns with the ones you find at the templair´s temples. just a clue :D

1;30 that pattern is symbolised by the myans

Wouldnt it be cool if it was possible to modify the sound signals so the sand actually make a picture instead. I wont mind making one of these and seeing what happens. How could would it be to have SSD (sand screen display) lol

Imagine this in HD running at 100,000 fps!

Why not do this to the recorded "alien" sounds and see what symbols they do.

something to do with the cells in your ears moving or changing or something. google it

Also, I always wonder in amazement how is that possible? What drives the particles to reformat in these arrangements? But sometimes a completely different question, I want to know what happens when you sprinkle only once and the frequency gradually increased. Unfortunately, there I do not found until now such videos.

could this explain crop circles then? Crystals align themselves to the frequency of the resonance!

what is it that doesn't make sense? Energy creates sound. Maybe energy doesn't need a creator.

@billman2112 Tolkien had the right idea. (The Music of the Ainur)

turned it up and my ant farm just went geometric, thanks a lot :P

@manchiald: Interesting remark !! In some mystical religous / creation / belief systems sound has the power of creation (look up Sefer Ha'yetzira). This is a practical demonstration of wave energy effecting the organization of material. Could you tell me where you saw that video?

i wonder if specific frequencies correspond to specific patterns.

Thumbs up for ear destruction at 0:39

this completly insane, i just cannot understand how this work lol i mean... why is this making this exact form!? and why not another form?

I'm sure it didn't like it too much...dogs ears are super sensitive. It was rough for me too :)

There is salt everywhere around it, lol

yeah

what is the significance of this? besides being utterly cool...

When I sneeze it makes my guitare resonnate.

So what happens when it goes beyond the range of human hearing? He sounded like he said "oops" when he turned it off. Do your eardrums explode?: Does the shape begin to start making patterns that only dogs can see? COME ON, KEEP GOING AND SHOW US. I'm guessing it becomes so complex that it frightens scientists when they see the face of god or something. Maybe it starts spellng out things that ends with the number 42.

You are describing an imbalance in chi!

@MagWrath yay, new crop circles

That's what I've been asking with my amateur knowledge of physics

lol, you can turn down video volume on the player

lol so this is how crop circles are made... haha

IMAGINE SOME DUBSTEP ON THIS!

@1:46...WIN!
