[@smartereveryday]

I've had a vision of making this video for almost a year. Thank you very much to Ford for making it happen! I feel that there are several PhD's worth of data in this footage. Seriously. If anyone wants to publish I would love to work with you on this.

[@jeromeneumann]

SmarterEveryDay If you ever get the chance to do this again, could you try to spray in some fog or vaporised water? at 4:18 for example, after the droplets exploded, it looks like there would form some sort of torus or plane in between the pressure areas. Anyway, a very interesting, beautiful and informative video...as always ;)

[@trued2010]

SmarterEveryDay I can still hear the higher pitches, :P

[@outinthegrapes]

I'd love to see this tried with a flammable liquid and fire.

[@deadsparky1]

SmarterEveryDay watching this i cant help but see planets and think that the gamma radiation from the sun as it calms down after formation provides areas of reduced pressure against the incoming radiation of the "background radiation" that allows for the surrounding gas to contract into bands then gravity takes hold getting bigger and bigger masses to the planets we have today

[@threadthathasnoend1212]

SmarterEveryDay could you update the wikipedia page on acoustic levitation, if you have time? it is terrible.

[@Alkosept]

You should have blown some smoke into the device. I think it would have made the actual sound waves visible.

[@AnotherWasted1]

Alkosept After seeing the pattern appear at 4:19 I thought it would be good to see with a light water mist from a spray bottle.

[@Peronioz]

You can see that at 3:59

[@Pawn_Burgundy]

I think Schlieren imaging would be perfect for this.

[@jonnupe1645]

Get fog machine or a person or vapes, exhaust smoke to the machine, get a laser pointer and wave it around the acoustic air pressure and the laser will show and highlight the changing pressure zones the smoke is experiencing.

[@papaversomniferum5247]

[@DoanDeland]

Regarding the machining on the Ancient Pyramids and Ancient Civilizations that preceded Egypt, I'm fairly convinced that the drill bit they used was a stone orb that was levitated using static acoustic pressure where it would oscillate and vibrate at tremendous speeds. This is how megalithic stone tablets were quarried. This also explains the precision in their stone working and their preference for the medium of stone. The Ancients were masters of vibration, sound, acoustics, and energy amplification and transmission.

[@experimentboyTV]

After seeing Physics Girl 's video outro about Chladni Patterns, I wanted to learn about acoustic levitation so badly... So Thanks for making this AMAZING video, and congratulations for working with awesome people again and... Phantoms !! *jealous* We'll always support you Destin! Now YOU have a good one! ;)

I think I could make an acoustic levitation machine, I really want to try that now! Do you happen to know the stats on the speakers used? Last time I did some acoustic experiments I blew an amp and lit a speaker on fire...

[@ScienceAsylum]

[@smartereveryday]

They're not speakers Ben... They are piezo motors. The "horns" are solid aluminum and they flap.

[@Nighthawkinlight]

SmarterEveryDay Essentially it's still a speaker though isn't it? Just with a different than usual mechanism to move the diaphragm? Do you happen to know why that's what is used?

[@ScienceAsylum]

NightHawkInLight Perhaps (Without giving too many personal details away, I live and work in southeast Michigan). It's been so long I can't even remember what class he was in... but I always remember your channel name, so it would seem his promotion of your channel was successful. Anyway, +1 sub.

2:13 I don't know why but this animation had me rolling around on the floor crying with laughter.

[@mizuhonova]

It would be interesting to programmatically nudge the pressure just to the point of popping and immediately reverse it after it tips. Would it split it two? Would a small amount explode but it immediately gets restored to a slightly smaller droplet than before? Would it split the water gently enough to bump the drop onto a different node? So many possibilities!

[@VEGETADTX]

Great point fellow Final Fantasy fan! ^^

[@1menatbpe]

yea. and I noticed that he didn't experiment to the endth degree like most of his videos.

[@InservioLetum]

@@1menatbpe Same... was really unfortunate, but I do understand why. This equipment is not in a price range you can afford to break. From the slow motion footage, however, it seems the further from the axis the water gets, the more the imbalance between the two waves factors into the sheetlet's stability. Flattened like that, droplet is a weird term LOL. I think if you could arrange a field of transmitters, you might actually achieve the effect you describe by modulating the field strength in real time, in much the same way the optical allignment correction in telescopes correct for atmospheric interference. [edit] typo's... can't let the errorists win.

[@mfbfreak]

@@InservioLetum *was in a price range. The video is 7 years old and the availability of those types of camera to us mere mortals has gotten so much better. The video is interesting, but also the fact that back then you had to travel across the USA to find someone with a high speed camera for 2 hours. As opposed to any science youtuber being able to buy one for a couple of thousand. Things changed soooo quickly.

[@PhillipSwindall]

I LOVE this video... not only does it show how raindrops and water react to pressure changes, it also shows that they can recombine and rebuild with other droplets from other sources (colors) and then re-explode, too! That was COOL!

[@sanbalakrishnan]

Im just here from Praveen Mohan’ video on ancient acoustic levitation. I was unconvinced until now. Thank you.

[@jacobhaig321]

I wish you changed the frequencies of the speakers.

[@anthonytamalonis]

Jacob Haig Me too! Unfortunately, the frequency is tied into the geometry of the transducers themselves, and is very very hard to change. We can change the amplitude (which was shown) and the relative phase shift (which was not shown), which moves the drops up and down in position!

[@deadsparky1]

***** i would predict that if the frequency of the top was slightly smaller you could efectly use it as a transport system

[@DawnOfErik]

deadsparky1 If the speakers have a different frequency the sound waves would be out of phase causing destructive interference, so dont think that would work sadly. Would be extremely cool tho!

[@steamcastle]

deadsparky1 I think you are right, but it would need only the smallest be lower. so something like 22kHz and 21.999,9 Hz remember don't move to fast just off the top of my head the speed it would move thing would be the wavelength of the average frequency times the difference in frequency. can that be right wavelength is the speed of sound / frequency , and the difference in frequency is well a frequency, so that should give a speed.

[@JWQweqOPDH]

DawnOfErik Nodes are destructive interference. You can actually make any two waves have the same frequency if you change the velocity of the frame of reference. Frequency is speed/wavelength. By making the frame of reference's velocity closer to the velocity of the sound with a smaller wavelength, you make the velocity (from the new point of view) smaller, and thus the ratio (speed/wavelength),AKA the frequency, closer to the other wave's.

[@HorkSupreme]

SmarterEveryDay Excellent! I thought this was a recent discovery. I will look it up promptly, thanks!

[@RMoribayashi]

SmarterEveryDay Any chance you know where I can find the video? I watched it live on NASA TV, which was on my cable back then. I usually had it on for every mission from takeoff to landing. The spheres were about 2 inches in diameter and they spun them like crazy, injecting air or oil inside.

[@HorkSupreme]

reece morrell Recent as in 5 or so years ago. My ignorance can not fuel your arrogance, do you face palm every time somebody says something you know but they don't? How childish.

[@SgtMantis]

I think something else is happening with the drops. Judging by observations in this video, it looks more like the circumference of the drop is exceeding the size of the node and anti node. Not simply being larger than the surface tension can handle, but then I didn't do any calcs, just observing.

[@upnorteeh]

SgtMantis It could be a mixture of both. At least that's what I have learned from my science classes.

[@12tman12]

SgtMantis From what I understand the nodes are going to be very small. In fact the only point where it's perfectly zero is a point. Any point below or above will start exerting pressure from below (to keep it suspended) and above as the waves move out of phase until the next mode, with max pressure being half the distance to the next node. So the drop always exceeds the size of the node technically. So the drop sits suspended at the chosen amplitude with a pressure from below and above and is already being squished even if it's not that noticeable. When they increase that amplitude, the pressure increases in both directions which squish the drop down. Until the point where the surface tension can no longer contain it and it breaks.

[@SgtMantis]

Well then i wasn't understanding what the experiment was. I thought they were keeping the wave constant and allowing the drops to break simply based on size, but adjusting the wave from and breaking the drops that way makes a lot more sense.

[@EZCarnivore]

SgtMantis it can be either the size of the drops or adjusting the sound, they did the latter in the second part with the American Idol people.

[@fudgesauce]

SgtMantis - I think he could have tested this by using liquids with different surface tension. Rubbing alcohol would have less surface tension than water, so if the size is determined by the equation he gave, it should rupture with smaller drops than water. If he used something thicker, like maple syrup, it would support larger drops. But if the size is being determined by the drops getting too big and getting ripped part in the anti-node region, the viscosity of the drops wouldn't matter.

[@zoltan1953]

So I watched this video right after watching your video about printable magnets, and it made me wonder. Surely acoustic levitation could be used to suspend a magnet. Of course you would need a very high amplitude to cause a solid to rupture the way water does. But what happens if you have some magnetic dust, say from crushing a magnet, clumped together, suspend it within the sound waves, and then turn the amps up? How much amperage is required to break the particles apart? How will they behave when broken apart? Will they seek each other out and form smaller clumps that can withstand the amperage or will they just fly apart like the water mostly did?

[@psyneur9182]

Instead of trying to explode the magnets with sound, you could just put in tiny magnets in the first place to make it slightly easier

[@ankitpaul9446]

I think it will behave like water droplets because to break magnet particle you need a sufficiently higher pressure difference between node and antinode right ? Such a high pressure difference will surely dominate magnetic force of attraction

[@zoltan1953]

PsyNeur Yes, that's basically what I was thinking. If you crush a magnet into small particles or powder, essentially what you will get is a bunch of tiny magnets. Sorry if I wasn't clear in the way I worded it. :)

[@zoltan1953]

Ankit Paul True. But then again, if you crush one big magnet into a bunch of smaller magnets, each of those smaller magnets would have a weaker magnetic force than the original larger magnet. As they attract each other, I'd assume that they would start to form clumps. As they clump together, they'll start to create larger magnetic forces. I'm curious to see if they actually will clump together, how big they'll get, and just how they will behave in general.

[@psyneur9182]

Ben E The clumping depends on if the force of the air pockets or magnetic fields is stronger.

[@geosekiro324]

I seriously haven’t been more surprised, just the fact that we humans can figure the length of sound waves is just mind blowing, AND we can levitate stuff with them

[@Sheldon.Williams]

At 4:10 when the droplet pops you can actually see the shape of the wave with the particles of the exploded droplet... Marvelous, Sir.

[@KronosOnPC]

And boom, this is definitely how the Pyramids were made! They must've been way more advanced than is thought.

Ignoring the fact that solids behave similarly to liquids under pressure. To be able to move blocks that large, the pressure needed would have turned them to dust. The true answer is the simplest one. Time and skill. The builders employed hundreds of laborers putting in thousands of man ours per day.

[@erikraudr1184]

You voted for Trump i guess

[@metascrape]

Great vid. The corporate sponsorship was handled tastefully too, I wouldn't mind more branded content if the commercial aspect of it was done as unintrusively as this vid. Also for the people shitting on Destin for his religious affiliation, I understand where you're coming from - I'm a former Christian, now atheist - but I think he handles in a tasteful way too. It's not in your face, and it doesn't effect the content of the videos, so leave the man be. With so many in the church being vehemently anti-science, it's refreshing to see someone who's open about their faith, but doesn't see it in conflict with science. Even if you personally believe the two are incompatible (which I do) - it's better that there are Christians in the pro-science camp in the public eye, as it discourages the extremist anti-science tendencies within their community.

[@TheWizardofLimes]

I wonder if you got big enough speakers, if you could levitate larger/heavier things or people. Or would just shake them to a sunder?

[@RicardoFuertes1990]

Levi Benezra you need an air presure able to lift a man againts the force of gravity, so oyu are looking at winds with higher magnitude than hurricanes xD

[@ricotasmium]

Levi Benezra or maybe spraying mist into the stream of levitation? Maybe it would condense into droplets or something...

[@TheWizardofLimes]

rico tasmium Coolest dehumidifier in the world.

[@anthonytamalonis]

Levi Benezra The heavier something is, the louder the sound would need to be (or the higher the amplitude would need to be turned to). Since the transducer is made of metal, at a certain amplitude it would shake itself to pieces and crack. Another issue with large objects is that a rule of thumb is the size of the object you can levitate needs to be less than the wavelength of sound used. Since we are using 22kHz sound, the wavelength is around 1.6cm, meaning we couldn't go bigger than that (in theory) even with a loud enough transducer.

[@anthonytamalonis]

rico tasmium Good idea, and it totally does that! If you look carefully, right at 4:00 Destin sprays water at the top transducer, which makes a fine mist. The mist then forms into small drops at the nodes, which helps you visualize the field and makes it easier to add larger drops!

[@robmoab3410]

That is the best slow mo I've ever seen! When the drops pop then come back together is amazing. Great work!

[@chantalharris604]

This is an amazing video. I am convinced this is what happens in space, gravity is actually acoustic levitation and you can see how matter is thrown out into the 'void' when the wave is disrupted. I am so excited to see this and wish it can be shown in schools.

[@Nenkos]

So why don't the suspended objects fall out to the sides?

[@eggspresso]

Aqueous Water The standing wave is not *just* in the vertical column between the two horns, but also in the space around the objects. They just stay exactly in between because there is the greatest pressure difference between the nodes and antinodes of the standing wave.

[@LordDragox412]

Aqueous Water Because they're spherical! Which basically means they're tiny planets and have their own gravity, and due to being cool looking things suspended in a device not usually seen around, they feel super hipster. So hipster in fact, that they'll throw away the Copernicus's "theory" about Sun being the center of our solar system, and instead assume that they're little Earths that are the center of the whole universe because that's what God wanted, meaning they'll stay suspended in one place. Trust me, I'm an engineer in Team Fortress 2, I know what I'm talking about!

[@z-beeblebrox]

Aqueous Water Think of it like how you can balance a ball on a jet of air - pressure waves act kind of like a pillow or stretched out fabric. When an object with noticeable weight sits on it, it bows in the middle creating a pocket for the object to rest.

[@dmxspider]

z beeblebrox would that imply it would not work in space since it cannot bow in the middle due to lack of gravity?

[@GotYourWallet]

dmxspider In space the device would be kind of unnecessary but I'd imagine with only two speakers it wouldn't be able to trap something.

[@maksime]

4:34 the mist is orbiting the sound waves, why?

[@AlftraZignTriOxide]

I was thinking the same thing. I don't think its orbiting so much. I believe its the same principle as why the droplets hover in the first place, but since its not in the middle of the standing wave it moves around.

[@FindingMartin]

sound moves fast homie. But for real its just where the waves end up going.

[@MrGainescu]

so i think i got this: in the image we depict soundwave as " ) ". or ) ) ) ) but bigger and biger. thats the movement of it. one frame of it would just look like " I " right? BUT that is ( for explanatroy purposes) the vertical axis. think about the experiment and looking from above and how it looks like? right " O " circle. and the watter molecules dance on the edge, also the " O " is formed on the less dense or where the sound wave connect and cancel eachother same thing as levitating them , (less presure) and the higher presure wave just bounces them back in place I o I Io I I o I I oI I o I . And now for the loopholes :

[@MrGainescu]

if is O and not a straight plane, why dont we see a plane full of watter and only a circle from the watter droplets? where did i go wrong?

[@BruceWayne-dh5hy]

The mist particles oscillate at a frequency same as that of ultrasonic waves. At each point, particles assume the amplitude obtained by the sum of the amplitude of interfering waves, resulting in the generation of high and low peaks. this wave is periodic, it follows Simple Harmonic motion.. that means it oscillates about equilibrium position. Since it is a high frequency, we see as if it is orbiting fast.

[@tiagopassarela]

that map at 2:13 made me laugh for awhile

[@Barefoot_Joe]

Me too, the goofy face cracked me up :D

[@flaplaya]

Kids can hear 22kHz. They were using a similar frequency as a text alert to fool their "deaf to that range" teachers.. Turns out the highest frequencies are the first to go in the aging process. I can actually still hear it which is amazing that I turn 35 on Friday.. I'm amazed at how rich this channel is with great content. Keep it up and we have a chance making it well into the 22nd century. Very impressed and grateful someone has stepped up to the plate.

[@100brokensticks]

You would need a pressure wave strong enough to push a person into the air (aka an explosion) and then you would need another explosion hitting them in the opposite direction at the same time to keep them in the same place, and then you need to do this continually so they levitate. And the same thing that happens to these water droplets would probably happen to that person :P

[@BerryTheBnnuy]

I can actually hear something very high pitch in some parts of the video... It's not constant. It kind of sounds like an audio glitch, but it's way higher pitch than I'm used to hearing on videos.

They talk about it just before turning on the machine that uses sound to levitate objects.

4'01" et 4'18" ... 4'36" , you see stability zones that are circles, about 5 or 10 cm away around the axis, at various height. even if they start the vid by saying they work in 1D, stability circles in 3D have to exist. it's mandatory. Inherent side effect.

[@finnaginfrost6297]

That is true, but the statement was one axis- they can't push things forward and back, or left and right- only up and down, but they can be stable to the left/right/forward/back of the main axis, just not moved or controlled.

[@NicholasBrule]

So the wave looks like a corkscrew? And the wave is just a 'Side Profile'?

[@Benoit-Pierre]

Not a corkscrew shape. Not sure how to explain it in english. Search for interferences in google image. You will find planar explanation of what happens. Now, imagine that the two sources of interfereance are at bottom and top of the device in the video. Apply the classic interferance picture along this axis (place one center of circle at each source), and make the pattern rotate around the vertical axis, without moving it upward or downward. Hot points on the main axis are the main stability points demonstrated in the video. But, around it, you have plenty of (weaker) donuts (or circles). The nature of things make them happen; and make them weaker. If youtube allows me to paste a link: www.sciences.univ-nantes.fr/sites/jacques_charrier/tp/interferences/acuv2.jpg

[@Benoit-Pierre]

Destin could easily draw us a 3D sketch of this; I am not good ad drawing. It's not an helicoid. It's a group of circles. At 4'36" you even can see som drops run along the circle. The video is going too fast; we would need a 1:10 or 1:100 slow motion video. I am sad Destin focussed only on the main axis, and did not mention the side interferances at all. At 4'18" they are hard to see because the figure is not stable at all. But at 4'36" there are about 8 circles in a conic shape; and drops clearly run counter clockwise along circles 3 to 5 (starting at bottom). Remember that, because you have only two sources, the pattern has to be completely symetrical around the main axis; that's why helicoid is impossible. Due to axial symetry, if you find one point, you can guess the circle. The pattern has axial symetry, exactly the same way as the planar picture I gave previously.

[@NicholasBrule]

Very cool, thank you for your explanation!

[@duncanmcharg]

G'day Destin, I would love to see more footage of when you sprayed a mist. There were some interesting rings etc happening, but only shown for a second or two, at 4:00 and 4:37 (< after the amplitude is increased and some drops disintegrate there are some very spectacular formations. Went one frame at a time :) ). Cheers

[@dhanursharma1752]

I find happiness in the small things and truly I thank all the technologies leading from the integration of transistors all the way to the Phantom camera coz of which I saw this beautiful video today!

[@KB-ld7jw]

That was trippy. Thank you for all your hard work SED.

[@binky2819]

I wonder if you could suspend drops of mercury in an acoustic levitation machine.

[@J0NES250]

And have a large bubble of the toxic stuff, ready to rupture? I see no way this could go horribly wrong. :D Well, perharps in an controlled enviroment. It would be cool.

[@carolynmmitchell2240]

J0NES250 you need to watch some cody's lab, it's mainly mercury salts and vapors that are dangerous not elemental mercury.

[@rjc4me]

a little far out of the base experiment. very interesting what the method would be though. for get the vaporizing mercury, that can be controled

[@rjc4me]

My unproven thoughts also. With an open mind...reality(?), universal law(?) is self-evident. The only truth I am sure of is the fact that I don't know the absolute truth. Peace

[@fermium1461]

probably not as its density is too high

[@ray-kast]

Could anybody else hear it (aside from the intermittent glitchy noises)?

[@MrFlarespeed]

Yep.

[@cynriclozano282]

+rookie1024 yup it was a wierd long sound

[@somedude5511]

I herd it

[@somedude5511]

I herd it

[@ray-kast]

It was inaudible when they heard it, but the mic picked it up.

[@FredGandt]

*Such a shame the **_amplitude_** didn't go up to 11* \m/ \m/

[@janemillerick9614]

(how to mystify and upset the dog.)

[@anthonytamalonis]

Fred Gandt Find me a commercial turn-pot that goes to 11, and I'll see what I can do!

[@FredGandt]

I believe they have to be custom made Anthony; Like tiny replicas of well known landmarks ;-)

[@FredGandt]

Most loudspeakers won't output frequencies above those a human can hear Jane. I think my dog is more mystified by my cooking than what I play on the computer. _"Why not just put food in bowl?!"_

[@janemillerick9614]

oh; mine's casual.. he'll eat anywhere.

[@Elzubi]

3:58 the best music for the best show ever! I LOVED IT !

[@lyricderbin]

Wow the shoot with the mist was just amazing.

[@captainsledge7554]

Haha giving the contestant's needles... starting that Hollywood lifestyle early.

[@captainTubes]

Lol good I wasn't the only one who wished there had been a more aesthetic choice there. A pipette conceivably. Hindsight is 20/20 they say

[@ps3Maniac246]

What I want to know is what would happen if you placed a small piece of paper cut into the shape of a circle (like the little piece of paper that pops out when you use a hole punch) and put it horizontally and vertically? Or does this only work for spherical objects?

[@bluebrains516]

Good question it an excellent thought i mite have to try it actally

[@ps3Maniac246]

+Blue Brains if you do, post a video for me ;)

[@HeroixMusic]

spray some mist in the acoustic levitation thing to visually see what you're talking about live.

[@Archanakoul]

I love science and you make me love it even more. Thank you SmarterEveryday. The last part of video looked like some trippy song video. A big Thank you for making this video.

[@kyleforster9930]

I DO NOT LEAVE COMMENTS EVER, but I must say dude you are awesome! I am a cardiac sonographer and I found this video to be extremely cool! Let me know if you ever want to know something about medical ultrasound. Thank you for you hard work.

[@Delta9D9]

That music sounds very similar to RATATAT loud Pipes. 4:19 to 5:28

[@justforever96]

Good song; haven't heard that in a while. But I don't think that sounds much like Loud Pipes...

[@sladesteinagel8544]

it does! (i heard that song on Pandora)

[@thejamir]

ChronicPain a shell in the pit

[@TheQuicksilver115]

I came to say this too, it's almost exactly the same..

[@deluxeassortment]

This is almost exactly how Ratatat sounds. Maybe SLIGHTLY less engineered and more organic. But I have been listening to Ratatat for 14 years, and I would have sworn it was then until someone told me it wasn't.

[@CERBERUS300ify]

maybe, the sound of the universe is levitating all planets and stars >

[@carsonfrith6801]

Or alien saucers bro....those droplets look pretty close to saucers if u ask me

[@denisestover2416]

At 4:18, when it explodes the smaller water molecules show the structure of the sound. That's neat! Good video! God Bless!

[@abdinasirosman2849]

thank you very much, I fully understood how sound waves work, I really appreciate the technical team for their simply and amazing demonstration.

[@loveaesthetic3136]

Hey its acoustic children

[@Magnifikate]

So what if our entire universe is being suspended on a massive standing wave

[@Inritus618]

Magnifikate What is the medium that the standing wave is travelling through?

[@RicardoFuertes1990]

Inritus618 dark matter?

[@Inritus618]

Ricardo Fuertes That implies, to me, that there is some sort of set of spacial dimensions that our universe exists within, and that also contains dark matter.

[@basicnpcc]

Magnifikate It it were, the entire universe would oscillate with the wave. I guess you could pass it off as something like waves under a massive ship, they are there but you can't feel them. This being said, it would still be a bit of a longshot.

[@TurkeyMeat]

Magnifikate RIP everyone everywhere.

[@TheFPSman1]

111:2 The works of the LORD are great, sought out of all them that have pleasure therein. Yeah, too bad the works of the LORD are nowhere to be seen in this video. I saw SCIENCE doing some work, though.

[@SKU11CRU5HER115]

Not only do you completely not understand. You also go out of your way to be derogatory to people who don't share your beliefs. Are you proud of yourself?

[@TheFPSman1]

I never outlined my beliefs.

[@TheFPSman1]

***** What's that?

[@jonoc5]

Ouroboros Please, do everyone a favour and just go away.

[@TheFPSman1]

jonoc5 Alright, it is rather late. Be back tomorrow boys, I look forward to your essays.

[@stunt40]

Bro you have made me smarter every day and still seeing stuff that blows my mind even though i know how it works

[@landown]

Hey Destin! First of all, thanks for all your videos :) I have to tell you, i've become really addicted to them. I am doing an engineering degree in madrid, spain, and I really love your videos, because there are a lot of things you talk about that I have learnt theoretically before, and they're a very cool experimental way of seeing that reflected in real life. And when you explain the reason why something is happening is like hey! I've seen that before! All my love and positive vibes from here! :D

[@ImNotACatLawyerButIPlayOneOnTV]

Had to turn the sound off, my teeth were starting to hurt.

[@JohnGottschalk]

The second slo-mo @ 4:37 shows this cool explosion where a ring gets kinda sucked back through another ring. Very rad

[@MrJames350z]

it looks like the space between the high points of the wave are getting closer together and thats "crushing" the droplets...really cool looking stuff here

[@tartarus216]

During the frames of 4:37 you can see the coalescing droplets trace the border edge of the waves by rotating around the center. Very nice recording!

[@michelleohlhoff5842]

Love love love this video. My kid now loves science because of this channel.

[@tkykii]

This is one of the best channels on yt

[@bradyzabawar4439]

While watching this video. I just came up with the PERFECT way of explaining this with my hands

[@ponyote]

Watching sound pull apart water droplets. Truly amazing.

[@enricogagarin9387]

You can also do this with your voice. Get a small (1x1 inch) square piece of paper and set it on a tabletop. Sing on an "ooo" vowel about an inch away from the paper. Slowly increase in pitch (gotta get real high up there) until the paper shakes, and eventually sticks to your lips.

[@josorr]

Best channel on KZbin, bar none.

[@MfundoPrinceMdlalose001]

Officially one of my most favorite videos anywhere.. reminds me of the movie Now You See Me 2

[@ZenonGamingPyro]

I forgot about shell in the pit and I'm lowkey really glad you used a song from them

[@maxwelll1978]

Awesome! As usual thank you so much for giving us another moment of wonder and delight.

[@athirar.p.3710]

At 2:11 you can actually see the really tiny blasted water droplets at the bottom forming a kind of sinusoidal wave! SO COOL!

[@snaprollinpitts]

hey Dustin, it makes a lot of sense when the amplitude is increased the neutral point gets smaller and that's why the drops flatten out and then rupture. it also makes sense that if a droplet is to large it will rupture. larger droplets might be possible if the frequency is lower. also at 4:37 you can see the rings that are most likely the neutral points within the areas of constructive or destructive interference. pretty cool. like you said there is a PHD worth if information within this video!!!

[@voca-chan7953]

I love the use of Parallels Desktop for controlling the high speed cameras. And especially the fact it was running Windows 7.

[@rgrstetson]

I like how they flatten before they give. They look so similar to galaxies immediately after explosion while they are still within the range of the device.

[@robertmillen2967]

One of the coolest things I have seen Thanks

[@connorr257]

This is some of the most impressive slow speed I have seen!

[@jayrich6532]

this video opened up a new place in my brain..wow!!! so awesome

[@padlockbeats151]

beautiful! best slo mo footage ive seen peace

[@MrSalvarion]

I love how you always say, you hope we enjoyed "this episode" of SED. To this day I have yet to find an episode that I did not enjoy. :D

[@TrollFaceTheMan]

Very cool video, thanks for sharing. Didn't know something like this existed.

[@renob422003]

Seriously F%*%*^^ing Cool. I like how the droplets flatten out before exploding.

[@oleksandrudod8246]

One of the most exciting video on SED! So many analogies in the world that surround us: water in our pipelines, rain drops, machineS for cutting metals with water under pressure, any liquid under pressure... even events beyond our sight occure according to those principals) How cool si that?
