The song in the video is my latest song. You can find it on iTunes or Amazon.

Song name: Dark Wave

All of the equipment for this experiment was provided by PASCO scientific

Leave a comment letting me know what your favorite pattern is. My favorite is 5284 hz (at 3:08).

So this experiment is the Chladni plate experiment. I used a tone generator, a wave driver (speaker) and a metal plate attached to the speaker. First add sand to the plate then begin playing a tone. Certain frequencies vibrate the metal plate in such a way that it creates areas where there is no vibration. The sand "falls" into those areas, creating beautiful geometric patterns. As the frequency increases in pitch the patterns become more complex.

Unedited version with tone throughout entire video:

as i understand it, it's actually inverse of what we're seeing. the parts of the board really vibrating are those without salt and where the salt gathers are regions where the vibrations flatten out

[moizzle]

i remember watching this seven years ago in university and this blows my mind now as much as it did back then.

[realalexesparza]

Looks like our old kitchen floor tile was running at 5284 hz.

[HereForTheMusic-ho]

I would love to see this represented in 3D space. Imagine if we could suspend particles in mid air and see how they arrange in 3D!

[abhinavtripathi]

This is what YouTube is actually meant for.

The patterns are dependant on the plate's shape too. So imagine how they would look if the plate had the shape of a circle, a triangle, a hexagon and so on

[judparn]

That's 2D. I wonder how will it look like in 3D. I am also curious how will the shapes transform in 3D during changes in Hz.

[Yace]

Sound manifests form. This is why music is so powerful.

[Oliver-dcnr]

turn the frequency nob slowly and then take a timelapse to show how the pattern gradually changes

[theotherme]

The level of design in the universe is mind blowing.

[KpxUrz]

This is astounding, eye-opening, and almost unbelievable. Think of the countless other aspects of nature that we cannot see and aren't aware of.

[pawelgotter]

It's amazing how the grains of sand are arranged. The symmetry of the resulting shapes is impressive. 3975hz looks awesome!
This simple experiment pleases the eye and works strongly on the imagination.

The vibration starts at the center and spreads at equal speed in circular waves towards the edges. Since the edges are not at equal distance from the center, the waves are reflected back at different times. At certain points the local sum of all the (amplitudes of the) waves going back and forth is 0, and that is where the grains will relocate to.



The shape of the pattern is decided by the frequency of the vibration, the rigidity/thickness of the plate and the shape of the outline of the plate.



On a circular plate you would get neat concentric circles where the gap between the gains varies based on the frequency of the vibration and rigidity/thickness of the plate.

Would be good just to have the actual tone, rather than the 'dramatic' music.

[angeloyanke]

This is so extremely fascinating. It's as though it's revealing the fabric of our reality that exists right beneath our noses. It's almost like in cartoons or whatever when they throw powder or paint on an invisible person to reveal them.

[DivMack]

Now here’s something crazy and relevant to how we process reality.

I had a DMT breakthrough and during this I heard all sorts of crazy loud alternating tones coming from within my head, so loud it was as if I had speakers in my ears. The room vibrated into extremely vibrant colourful geometric patterns and became completely indistinguishable as if it was not a physical object, creating impossible shapes and merging/morphing in all different ways.

Seems like the DMT caused vibrations in my mind that altered my perspective of reality. I watched a solid room and reality itself morph and change like the salt on that plate.

[yogiefebriady]

A friend of mine once said that he can see the shape of sound when he's high...

Well, I'll be damned.

[thomasmartinscott]

I'm just imagining what music does to our bodies and brain cells. I KNOW some is calming and some is nerve-wracking, but it would be interesting to SEE what is actually happening, don't you think?

[dreamlesssleepart]

It's so crazy that this stuff and these patterns exist I literally EVERY aspect of our universe, from plants to the way our proportions are shaped

[hcic]

Singlehandedly, thee most amazing thing I've ever witnessed. (Without one drop of exaggeration)
