Thanks for the video Adam.

wow. that was cool

REALLY COOL!!!

NICE!!!!

I like'd :]

Ow. my ears.

Very intresting!

:)

The interference-pattarn at 1:30 was pretty nice.

veri sudas

I know what makes the salt act like that: 1. Soundwaves, the are naturrally in PATTERN 2. move with 340 meters per second 3. The salt begin to move with the soundwaves. 4. When the sound is so loud that the salt start to shake on the speaker, it lifts and is picked up by the soundwaves. 5. A pattern that interfer with a large amount of small materials , as salt, creates a pattern of the small materials.

the 1:50 is cool!

Cool, but i dont see any logic in the forms of the pattern... I mean I get what Tobbe was saying, but why THESE patterns are formed on certain frequencies, some of them look very complicated. Can anyone explain or link to a site that explains?

SUKA NAXUI LOL PIDARAS

very interesting :)

OMG THATS COOOOL!!!!

As the pitch increases, the pattern complicates due to the expression of higher order harmonics. Like a half-wave length antenna wire ALSO is resonant at 1/4 wave, 1/8 wave, 1/16 wave, etc. Since this is a planar surface instead of a linear wire, the possibilities for complexity are greater due to the 2-dimensionality of the flat plane.

salt?? pah! you should have seen the effect that that noise had on my dog. :p

it has to do with the certain frequencies that the plate of metal will resonate them, you will notice as the note gets higher, the 'regions' that form in the salt get smaller and more numerous as the note gets higher. im no expert, so dont go qouteing me, but i remember doing something similar in highschool physics using an ultra sonic generator and plates of various shapes.

Unbelivable !! O_O

The sound waves in the plate interfere with each other and the salt accumulates at the 'knots', the boundaries where there is a destructive interference. The shapes look like something out of my quantum mechanics class, a waveform or something. Really nice! :D

its all the same shape, the only thing changing is the wave is geting faster (or shorter) as the pitch goes higher

Yeah the patterns reminded me ideed of the hydrogen-atom patterns according to quantummechanics... only these are 2D.

they should use glass beads then pick paterns for fibreglass parts

the coolest salt-sound video i ever saw 10/10

wrelly nice ir tiem kas nesuprato,paaiskinu,cia druska reaguoja su muzika xD.

mmm... nice little salt fractals... it sounds a bit like a snack, doesn't it?

i've never seen smth like this- it's very interesting and amazing

interesting

kas tai?

that's cool

sdsd

my dog is going around in circles hum....

this is good jega nx :D

If you look closely, the beginpattern is in every new pattern(if you look with a bit of imagination) Therefor sound always has the same pattern, only at higher tones the pattern gets more complex

wow pretty cool, for the first little while i was thinking, damn, this could be an xbox commercial

i wonder if i fart if i can get the same effect

Salt+Sound=Magic :-)

aw, my ears, cool though

makes me want to howl!

They are formed by standing waves, and the addition and cancelation of waves. We did this in a physics lesson and i have a test on it in a week, i really should know more about it...

how would you recreate this? metal plate + salt + something that vibrates the plate with sound waves? if not too expensive i would love for my neice to do this as a school project.

So that's how crop circles are formed

wow!

really neat didnt know that would happen.d

Now that was the point.... incredible what sound can do to matter... imagen water and bodies! =)

NO WAI!!!

sweeet

gobblox (guest) it has to do with the certain frequencies that the plate of metal will resonate them, you will notice as the note gets higher, the 'regions' that form in the salt get smaller and more numerous as the note gets higher. im no expert, so dont go qouteing me, but i remember doing something similar in highschool physics using an ultra sonic generator and plates of various shapes. he's right

GG

Amazing !

strange

My blood presser went up, my dog pooped himself, and now I’m deaf! Thanks

great ! ever seen the same with water, also amazing...seeya

croire a des chose non vue

amazting

The visuals of sound! =) amazing

sweet

I saw this video somewhere else before, but they said it was rice, not salt. But who cares, it's cool ;)

LoooL! Amazing!

Oh man.. That's cool!

How does this work?

OWWWW!!!!! not goood listening too that with a headache i suppose.

It really has nothing to do with sound. Sound is just a byproduct. What they're doing is just shaking the platform at increasing frequencies. All objects have certain frequencies that they resonate at naturally. These frequencies are special because the waves of vibration traveling through the surface create a standing wave, much like when you shake a jump-rope with one end tied; when the peaks and troughs, and more importantly the nodes, stay in the same spot. The sand, salt, rice whatever, then moves away from the parts of the surface that moves from peak to trough and gathers in the spots where the nodes are (the areas of the syrface that move the least.)

This explaines patterns at cornfields (ufo).

oooh that hurts my hearing holes but it's purty

oooh that hurts my hearing holes but it's purty

Awesome!

It;s all about vibration ( like samurai explained ,but don't rule out the sound. Sound( tone hight)will increase or decrease the resonance in the board.

goatse for the ears but It looked really awsome, seems like the kind of thing I would do in science

awesome

Close Encounters of the SaltSound Kind

Wow, how amazing. Something amazing as this, yet not one "white fish." :}

Mr. Tobbe - I am afraid your answer would not suffice in a high school class, much less a class with sufficient theory to predict these patterns. Yes, sound is a wave. Yes, you see patterns. Now, please try again.

hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhg g g ghgggggggggggggggggggggggggggggggg

I still have tinnitus even after a few minutes of reading. [b]Samurai,[/b] I thought sound was vibration, and it was that vibration which travels through the plate and creates the partials to move?

That is awesome, and as usual, some fagget gave it a negative and didn't post. Faggets

human beings are soooo wonderfull!

the last tone was hard to hear coz its so high pitched. i couldnt believe my eyes!

wtf the people saying this explains crop circles...NO IT DOESNT.

can you tell me how to make that thing??just email me if have time> katrina_708@yahoo.com thanks!

why wont it work? the video i mean

oddly some of the later ones remind me of crop circles ... I dunno why but cool stuff regardless

That's understandable that cash can make us free. But how to act if someone doesn't have money? The only one way is to receive the credit loans and small business loan.
