the presentation of this app is really good of course, it could just be an audio file that you play, but the rotating "fan" which you can actually interact with really sells the illusion
Know what's really funny? I saw apps in the play store claiming it "blew air" and would cool you off. The reviews were hilarious because SOME people actually believed it would cool them off...and complained that it did not blow air. Lmfao..like they actually thought air was gonna come off an animated fan image on their screen. lol.. I took screen shots just because. So dumb... 😄
As someone who works with speakers for a living, I'd like to give everyone a friendly fore-warning. This is a cool parlor trick to move air - - but it's not good for your iPhone's speaker (or really any loudspeaker for that matter). When a speaker's surround excursion gets broad to move air like this, it is put under a great deal of stress. Over time, the surround will weaken and rattles will develop. Distortions will grow and in many old iPhones ....you'll notice that the speakers can sound "crackily". Apple and the other manufacturers work hard to develop tiny speakers that produce a full frequency response inside of your phone. I really rely on it and use it a lot. And for the cost of an advanced phone these days - - I'd rather take care of it so that it lasts as long as possible! Addendum: playing the speaker at fixed low frequencies and high volume for periods of time will also heat up the surface mount audio amplifier, reducing not only it's life but also the nearby components on the board (and who knows what that part may be in a crammed iPhone)

I've definitely noticed while playing my Quest 2 that, when the volume is cranked, certain sounds will actually blow air across my head/ ears, I don't think it was actually a planned feature but it does work to increase my immersion
@@meipei2423 Is it? It literally only happens in perfect sync with specific sounds (like explosions) when the volume is up, not like the constant hum of the fan. If that is the fan doing that then that's a cool feature but I've never heard it talked about
You literally finally gave me the answer to how sub-woofers create so much air when you listen to music loud, while they in fact just vibrate so the sum of air moved is zero. Now I know... it's just because when it pushes out it's coherent, but when it sucks in, it's not :)
Also, lower frequencies have longer wavelengths - he showed this with the sine wave generator, as he lowered the frequency the wavelength increased which resulted in the candle being blown out. So while low frequencies still have compressions and rarefactions, the wavelength can get so long that each of those phases can encircle an object such as a candle flame.
I think that would only work if you're in front of the port (hole). I don't think it would work if you are in front of (or behind) the subwoofer cone because it's not a concerntrated flow there.
Just go to a bass competition. They shatter windows. You learn a lot about this stuff while building boxes. You need the air space for the speaker to match the air for the proper frequency the speaker is rated for. Having the right box for the subs is essential to get the proper sound. There are systems out there that can blow a candle out from outside the car easily. Not mine.. but I know a guy who is on his third windshield created by the force of his subs. It's amazing!

Mighty interesting! I’ve studied music technology & sound design, and even have developed mobile audio apps for a couple of years, but never considered the air coherency stuff you discussed in this video. Thanks!
Thanks for this. Nicely explained. I'd like to suggest using smoke from an incense stick or the like, instead of the flame, for exploring the flow patterns. Less risky and I think with a longer-affected column. On a somewhat tangential note, I think an incense stick or the like could be used to measure the airflow in a room. This is especially useful in the time of COVID. Good airflow and exchange is as useful as masks are.

Same principle as what the two engineering students from George Mason University who invented a new fire extinguisher, capable of putting out flames by manipulating sound waves. Very thorough thanks for the extended explanation, very interesting. Keep up the great content!
Most of my college years I spent rigging subwoofers for people's rigs. Of course speakers can create positive air pressure. Just ask anyone with an inverted subwoofer box, carrying two 12-inch, 1000W subs with holes on the sides. It definitely creates an intense force. Same principle, different scale, different frequency.
There's actually a fire extinguisher that uses sound that was developed by students at George Mason University in Virginia. It's being tested for wild fires here in California
@@asdf52708 this is the original youtube video. The device being reviewed is slightly different but utilizes the same concept th-cam.com/video/uPVQMZ4ikvM/w-d-xo.html
thanks I remembered reading about that a few years ago but forgot which school they were at. if I recall correctly they ended up securing DARPA funding.
I knew if this was true it would have to be the waves, but I was stumped on the same "zero sum game" thing. The fact about blowing generating more coherent air compared to suction was fascinating and somehow escaped me all my life despite encountering it all the time.
Well, I'm a qualified sound technician and I don't remember this ever being explained to me. It's counter-intuitive. So this would only work when the displaced air is passing through a small hole (relative to air displacement over time). So it would create this concerntated ("coherant") air flow during the positive pressure phase. Cool.
@@roshanantony64 practicality is a matter of application. Might be a good way to make an insulin pump, for instance. A tiny aquarium pump would be vastly oversized for that application.
SY3D H3RO 7 months ago (edited) There is a sound frequency which can not only blow air but can extinguish a medium level fire but you need slight bigger device than phone ( I knew someone made this device in my college project) 😁👍
Ah man I love this! I've always been so fascinated with sound waves. I actually did this for my first science experiment at school and then after doing some research I found out that sound levitation and frequency are completely misunderstood
This is why my subwoofer blows my hair about when I turn the volume up in my car. Feels like a constant stream of air going round. Great explanation! I already knew this, but nice to see visual examples with the vacuum cleaner. You're great at explaining things. :)
When I first saw your channel I really thought it was just another hydraulic press channel copycat thing, but over the years I have been pleasantly surprised by the variety and quality of content you upload. I am glad I didn't unsubscribe, you deserve it man. ^^
Ah I made a fire extinguisher based in the same concept but used a whole Bluetooth bass speaker, for my interschool competition. The best it could do was a couple of candles from a short distance. Controlled the frequency using Phone app. We did won the competition. Glad to seeing it getting explained on TH-cam.
I mean it makes sense, sound is just the variation in air pressure waves, which have a measurable frequency. Frequency determines pitch and so on and so forth. So my theory would be that it uses sound to blow out the candle. Or at least that was my thought when I read the title of the video, anyways.
The only thing I was missing was an animation of particles moving incoherently during the sucking-phase and then particles moving coherently, as a stream, during the blowing-phase. Anyway, great explanation with adequate level of detail!
You can demo sound just being air blown about really well with subwoofers in a car. The subwoofers will be separate in an enclosure in the boot/trunk but still easily flap the air around Inside the car. I even had an odd experience when I wired one of two subwoofers incorrectly so that one sub completely canceled out the sound of the other sub. Moving the stereo balance left to right had loud sound on either left or right but no sound when it was both. Luckily my dad realised what it was as soon as I explained it, they were going out of phase I think they call it?
Fun fact: this is the same phenomenon that powers noise cancelling headphones. Two sounds thats are each others’ inverse completely cancel out due to destructive interference.
Yep.. And some of the most exotic subwoofer enclosure designs use that phase coherency to their advantage to make a small sub like a 6" perform as good as one many times its size with more power. The design of course is really complex and often unwieldy to build into an enclosure. But the effects can be quite impressive.
@@wishusknight3009 box and install is 90% of what matters in a audio install. You can have a 10k top of the line speaker but if you did a crappy install and used a crappy material/design then that speaker will sound just like a $50 speaker in a proper box.
1:51 this is exactly how electrons carry charge... just like the red highlighted particle... a single electron doesn't move the length of the wire but rather is wiggled somewhat in place by the electromagnetic wave. As an electrician and electrical engineering student, and overall electricity enthusiast I end up in conversations where I'm trying to explain this phenomena to others and you just gave me the perfect visual animation ... now I can just pull this up on my phone and show it to them and say 'it works like this'...
Actually, it utilize a specific programming language to manipulate physics and interact with the environment; calling upon demons by simplifying the old summoning process, without the hassle of conjuring them with specific requirements or medium, as well as providing a field of magnetite for the demons to be realized into our world...as long as you have enough in-ap...I mean, Macca.
That's extremelly informative and cool Dude, seriously, you took a simple topic and explained it into a creative informative educative and enterteining way, now I understand why my case fans doesnt blow more air when I take the frontal plate off, because the frontal plate has air entrances on the side so it sucks almost the same ammount of air as if there was nothing in front of the fans
Actually sound can make particles travel really long distances. If you've been to a concert standing in front of a subwoofer, it goes as deep as 30Hz. The wavelength that a particle travels at 30Hz is 10,37 metres. At a sustained bass guitar note, the subharmonics behave as an industrial fan.
@@shahnawazhaque7243 A particle does not really travel anywhere, it just vibrates back and forth and this distance is called wavelength. And wavelength (λ) is directly related to frequency (λ=c/f) where c (speed of sound) which we assume is constant 331m/s. Amplitude is just how far the membrane pushes the air but it won't make the particles travel further, just more mess is being moved. But I'm not sure with the amplitude part, it's probably more complicated than that :)
Me watching this video: Start: “Oh, well it’s kind of obvious” Middle: “Oh dang, maybe I’m not that smart” End: “Actually yeah, it was kind of obvious 🤷♂️”
Thank you for teaching me so much stuff over the years I didnt even know I needed to know lol it's always super interesting and crazy I just learned so much about sound and air

It’s kind of funny that this app costs money when you can easily recreate its effect for free XD Also, this app is old news, but thank you for covering it! You actually explained the science behind it unlike everyone else who talked about it :)
@@ronal8824 oh, I see. But the thing is you can’t replicate a snow globe yourself without the proper materials and knowledge. But this? All I had to do was download a free app that is used to produce different frequencies (and the app was used in the video, btw), set it to a relatively low frequency, and that’s it. I had air flowing out of my phone’s speakers completely for free! Not to mention I have more customizability with this app too. So why would you pay a single dollar for an app that just takes the free app, limits it, then brands it?
@@xXmlgamingXx355 I think "an app to play different frequencies" would count as "proper materials" and "knowing the frequency" would fall under "knowledge".
Love the video, love the channel. I'm just wondering if a sawtooth wave could be as or more effective than a sine wave; would it force air more efficiently or just make it sound cooler?
Xiaomi has something that is used to clean the speaker of the phone. That is by using an high volume sound in some hight range. Very noisy, but it actually blows air. A speaker can blow air because it vibrates when it sounds. Funny. And I have only seen 0:29 seconds of the video BTW
I noticed this some years ago with my Galaxy S6. I was listening to an audio book and I felt the air on my hand. I wonder how good this is for the speaker to be constantly at it's limit on a set frequency (They drive these things quite hard to reach the volumes they reach at this size). There are smart amps that are designed to protect the speaker while using every bit of excursion, but things can fail, just like OCing your CPU etc.
my phone already does this; when my volume is up, some air leaves the speaker, the reason why i'm keeping this phone is that despite it being slow and bad, is that the air-producing speaker makes people shouting at me in phone calls very realistic
I’ve noticed this phenomenon when I was younger! I always wondered why the force was so different. Also, “now I’m going to talk about sucking and blowing” THAT’s WHAT SHE SAID 😂🤣
Well, you remembered me a VHF Handheld Marine Radio I had, that had a function called "AquaQuake": given it was waterproof (ip67) but still it was possible to have some water stuck on the grid, by activation this function, the speaker would have emitted a low-frequency hi-volume tone, vibrating vigorously, to help getting rid of the water on the grid. I understand this function is also present to a lot of similar handheld marine VHF radios Very interesting, anyway
@@Somethingafw Question: Do you know some good science-channel you could recommend to me? I always search for more; and would be glad i can return you the favor.
Ohhh, this is how those putt-putt boat toys work! The heat sucks in water, then when the water goes back out, it’s only moving coherently in one direction
Actually, the laws of physics are a bit tricky you see. Nothing in the entire universe is ever pulled or "sucked". Things are always pushed. The high pressure is always pushing into the low pressure giving the illusion of pulling.
It's great to see content on this channel that shows how physics in the real world works. Basic high school physics will tell you that sound doesn't move air but real physics isn't about frictionless, idealized models behaving in a vacuum.
Very interesting. My personal question now is, why do the rules of physics state that sucking and blowing act differently? Why does blown air move in a coherent tube? Why doesn't air move the same way whether it's being blown or sucked? No doubt there is a reason, but I do wonder what that reason is.
because of the direction of flow compared to the shape of the tube. In sucking the tube that makes the air coherent comes after, in blowing the tube that makes the air coherent is before.
resume for newbies: sound is air pressure, and the higher the frequency (tone) the more air youre moving therefore creates air current and lets you "blow air"

Just ask anyone with an inverted subwoofer box, carrying two 12-inch, 1000W subs with holes on the sides. It definitely creates an intense force. Same principle, different scale, different frequency.
4:57 that what she said
There's actually a fire extinguisher that uses sound that was developed by students at George Mason University in Virginia. It's being tested for wild fires here in California
Nice to hear that
how would that work? I'm a licensed fire suppression technician and everything I've ever learned tells me that it's not possible.
@@asdf52708 this is the original youtube video. The device being reviewed is slightly different but utilizes the same concept th-cam.com/video/uPVQMZ4ikvM/w-d-xo.html
But wouldn't a good ol' leaf blower be more effective as far as blowing goes ?
thanks I remembered reading about that a few years ago but forgot which school they were at. if I recall correctly they ended up securing DARPA funding.

3:22 thanks for the clarification 😂
I knew if this was true it would have to be the waves, but I was stumped on the same "zero sum game" thing.
The fact about blowing generating more coherent air compared to suction was fascinating and somehow escaped me all my life despite encountering it all the time.
Exactly!
The crux of the video
I feel the exact same way!
Well, I'm a qualified sound technician and I don't remember this ever being explained to me. It's counter-intuitive. So this would only work when the displaced air is passing through a small hole (relative to air displacement over time). So it would create this concerntated ("coherant") air flow during the positive pressure phase. Cool.
Put a check valve somewhere in the system and you've made a pump.
@@punkinhaidmartin very, very weak pump and can't be practically used for anything imo
@@roshanantony64 practicality is a matter of application. Might be a good way to make an insulin pump, for instance.
A tiny aquarium pump would be vastly oversized for that application.
You can feel it on some subs, there's a very noticeable breeze on the ports
@@punkinhaidmartin for medical shit they generally use peristaltic pumps, that way all the surfaces that contact the fluid are medical grade tubing.

There is a sound frequency which can not only blow air but can extinguish a medium level fire but you need slight bigger device than phone ( I knew someone made this device in my college project) 😁👍
Ah man I love this! I've always been so fascinated with sound waves. I actually did this for my first science experiment at school and then after doing some research I found out that sound levitation and frequency are completely misunderstood
This channel is where physics videos were 10 years ago and I like it reminds me of simpler times
This is why my subwoofer blows my hair about when I turn the volume up in my car. Feels like a constant stream of air going round. Great explanation! I already knew this, but nice to see visual examples with the vacuum cleaner. You're great at explaining things. :)
It's very comforting to know that if I ever forget the difference between sucking and blowing, I can always come back to this video.
No, Helen, don't blow! BJ is just an expression!

1:15 I like that nobody's questioning what the particles are. Just some good ol fashioned white particles I guess, lol
Ah I made a fire extinguisher based in the same concept but used a whole Bluetooth bass speaker, for my interschool competition. The best it could do was a couple of candles from a short distance. Controlled the frequency using Phone app. We did won the competition.
Glad to seeing it getting explained on TH-cam.
1:22 ya know got to dust off my left over coke before I start anew
LMFAOOOO
This guy actually keeps his phones speakers near the candle flame; big respect you ;)
I mean it makes sense, sound is just the variation in air pressure waves, which have a measurable frequency. Frequency determines pitch and so on and so forth. So my theory would be that it uses sound to blow out the candle. Or at least that was my thought when I read the title of the video, anyways.
The only thing I was missing was an animation of particles moving incoherently during the sucking-phase and then particles moving coherently, as a stream, during the blowing-phase.
Anyway, great explanation with adequate level of detail!

I guess its using the phone speakers and creating sound waves to mimic blowing air
you don't have to guess.. he explained how it works pretty thoroughly

that reminds me of something

“Ofcourse it’s fake, it’s sound waves”

“Holy shit I’m a genius….”
This is like that time I found an app that apparently detected metals and seeing the reviews I tried it out, I was surprised and amazed when it work
What app was it?
But only ferrous metals, correct? I believe its the built-in magnetometer at work
@@pipsta I think it was called "Metal Detector" straight up
You can demo sound just being air blown about really well with subwoofers in a car. The subwoofers will be separate in an enclosure in the boot/trunk but still easily flap the air around Inside the car. I even had an odd experience when I wired one of two subwoofers incorrectly so that one sub completely canceled out the sound of the other sub. Moving the stereo balance left to right had loud sound on either left or right but no sound when it was both. Luckily my dad realised what it was as soon as I explained it, they were going out of phase I think they call it?
Fun fact: this is the same phenomenon that powers noise cancelling headphones. Two sounds thats are each others’ inverse completely cancel out due to destructive interference.
Yep.. And some of the most exotic subwoofer enclosure designs use that phase coherency to their advantage to make a small sub like a 6" perform as good as one many times its size with more power. The design of course is really complex and often unwieldy to build into an enclosure. But the effects can be quite impressive.
@@wishusknight3009 box and install is 90% of what matters in a audio install.
You can have a 10k top of the line speaker but if you did a crappy install and used a crappy material/design then that speaker will sound just like a $50 speaker in a proper box.
It's actually called phase cancelation.
@@MrEazyE357 thank you, I thought I might have got that wrong.
1:51 this is exactly how electrons carry charge... just like the red highlighted particle... a single electron doesn't move the length of the wire but rather is wiggled somewhat in place by the electromagnetic wave. As an electrician and electrical engineering student, and overall electricity enthusiast I end up in conversations where I'm trying to explain this phenomena to others and you just gave me the perfect visual animation ... now I can just pull this up on my phone and show it to them and say 'it works like this'...
This theory makes sense for AC but how do you propose it holds for DC where there is no "wave"?
@@xswordslashx4283 In DC, the positive charges move along the wire, the rate that they do is the current.

That's extremelly informative and cool
Dude, seriously, you took a simple topic and explained it into a creative informative educative and enterteining way, now I understand why my case fans doesnt blow more air when I take the frontal plate off, because the frontal plate has air entrances on the side so it sucks almost the same ammount of air as if there was nothing in front of the fans
Actually sound can make particles travel really long distances. If you've been to a concert standing in front of a subwoofer, it goes as deep as 30Hz. The wavelength that a particle travels at 30Hz is 10,37 metres. At a sustained bass guitar note, the subharmonics behave as an industrial fan.
Wouldn't the amplitude (volume) of the wave be relevant to how far a particle travels rather than frequency
@@shahnawazhaque7243 A particle does not really travel anywhere, it just vibrates back and forth and this distance is called wavelength. And wavelength (λ) is directly related to frequency (λ=c/f) where c (speed of sound) which we assume is constant 331m/s.
Amplitude is just how far the membrane pushes the air but it won't make the particles travel further, just more mess is being moved.
But I'm not sure with the amplitude part, it's probably more complicated than that :)
It’s the sound waves of a specific frequency which is blowing out the candles.

Start: “Oh, well it’s kind of obvious”
Middle: “Oh dang, maybe I’m not that smart”
End: “Actually yeah, it was kind of obvious 🤷♂️”

@@ronal8824 wdym?
@@ronal8824 oh, I see. But the thing is you can’t replicate a snow globe yourself without the proper materials and knowledge. But this? All I had to do was download a free app that is used to produce different frequencies (and the app was used in the video, btw), set it to a relatively low frequency, and that’s it. I had air flowing out of my phone’s speakers completely for free! Not to mention I have more customizability with this app too. So why would you pay a single dollar for an app that just takes the free app, limits it, then brands it?
But it made you question the phenomenon you never thought of before
@@xXmlgamingXx355 I think "an app to play different frequencies" would count as "proper materials" and "knowing the frequency" would fall under "knowledge".
@@somdudewillson I guess, but it’s a lot simpler too. I just think that paying for a limited version of something that’s already free is dumb.

The fan on the app that you can interact with definitely sells the Illusion
Xiaomi has something that is used to clean the speaker of the phone. That is by using an high volume sound in some hight range. Very noisy, but it actually blows air. A speaker can blow air because it vibrates when it sounds. Funny. And I have only seen 0:29 seconds of the video BTW
I really need this app, it blows better than my wife. 😆
That's rough
Let's hope your wife doesn't find this
xDxDxD
She’s definitely not a keeper, that’s not a bird, she’s a nerd
I noticed this some years ago with my Galaxy S6. I was listening to an audio book and I felt the air on my hand. I wonder how good this is for the speaker to be constantly at it's limit on a set frequency (They drive these things quite hard to reach the volumes they reach at this size). There are smart amps that are designed to protect the speaker while using every bit of excursion, but things can fail, just like OCing your CPU etc.
Dude, I love your videos. I always learn something new, and you explain really well.
You learn something new every day.
my phone already does this; when my volume is up, some air leaves the speaker, the reason why i'm keeping this phone is that despite it being slow and bad, is that the air-producing speaker makes people shouting at me in phone calls very realistic
Why are they shouting at you
Buddy you ok

Well, you remembered me a VHF Handheld Marine Radio I had, that had a function called "AquaQuake": given it was waterproof (ip67) but still it was possible to have some water stuck on the grid, by activation this function, the speaker would have emitted a low-frequency hi-volume tone, vibrating vigorously, to help getting rid of the water on the grid.
I understand this function is also present to a lot of similar handheld marine VHF radios
Very interesting, anyway
Also in smart watches my Samsung watch emits sound after I turn off swim settings and it shoots the water out.

Actually, the laws of physics are a bit tricky you see. Nothing in the entire universe is ever pulled or "sucked". Things are always pushed. The high pressure is always pushing into the low pressure giving the illusion of pulling.
It's great to see content on this channel that shows how physics in the real world works. Basic high school physics will tell you that sound doesn't move air but real physics isn't about frictionless, idealized models behaving in a vacuum.
Very interesting. My personal question now is, why do the rules of physics state that sucking and blowing act differently? Why does blown air move in a coherent tube? Why doesn't air move the same way whether it's being blown or sucked? No doubt there is a reason, but I do wonder what that reason is.
because of the direction of flow compared to the shape of the tube. In sucking the tube that makes the air coherent comes after, in blowing the tube that makes the air coherent is before.
@@TheActionLab Cool! It's "obvious" - once you explain it... :-)

resume for newbies: sound is air pressure, and the higher the frequency (tone) the more air youre moving therefore creates air current and lets you "blow air"
