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)
Wow. You teach very intuitively and many of these subjects are actually nuances in science education. Watching your explanations makes me feel smarter :) . If more people understood these principles, the world would be a much nicer place. You have a powerful brain!
The most amazing thing about this channel is how many ideas for videos he comes up with. Sometimes, the explanations are simple and sometimes they reveal some complex or hidden phenomenon, but the result is always fascinating. In addition to being very technically knowledgeable, The Action Lab is extremely creative! It inspires millions to learn about science and to be curious.
I just finished physics, i didn't expect to take an extra class 😂 especially because you are super oddly similar to my teacher. But that was amazing as always, you are genuinely one of the best channels on youtube, your videos can't get boring.
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.
Well he appears to be fully grown adult male. There's your science. It you are also a fully grown adult male who can't keep a straight face for that reason.... Then that's where the scientific wonder lies, my friend.
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! I have a video of this girl with her hair bouncing everywhere from outside the car. Its so cool!
@@dragonapostle in a couple of years none of it will make any difference because all you will hear from the moment you wake up to the time it finally let's you sleep will be a very annoying ringing sound. Trust me on this you don't want it.
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

@@alkasaket379 here's few out of top of my head: remote control, radio receiver, console gameplay (extra controller, game maps, screen mirror etc) 3d depth screens thanks to gyro , interactive comic books, AR games and so on...
@@alkasaket379 None. These never died out, and neither are they supposed to happen. You just use an app to misuse something already existing. Blowing out candles with a phone; you're using the vibrations from the microphone. Remote control? Just connecting it to the TV. There are new appliances to help with that. None of this died out; it's not something you saw "back in the day," when people were more "classy" and "interested." No one had time for it.
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
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. This is unfortunately hard to do in a restaurant, but meeting rooms, classrooms, etc., it can help.
Wait, i thought there were all sorts of particles in incense smoke that would coat any surface close to the burning incense stick. The only time I've seen an insence box, there was oily soot all over it and the wall around it... yes I touched the soot thats how I know it was oily and yes I regretted it immediately. If that is true, then it could seriously mess up the phone's speaker by covering it in a layer of stickiness.
Covid-19... The virus with overblown death numbers... The virus that 90 year old, senile, and dementia ridden Joe Biden that was vaccinated and boosted and still got and tested positive for Covid-19 twice.... "survived".
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. :)
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
We could preinstall big speaker systems generating the right frequency in areas where fire/smoke is detected, effectively replacing sprinklers or adding to them.

this is similar to those put put boats (toy boat powered by a candle) it just pushes and pulls water, but because the pull is conteracted and the push isn't, the boat moves.
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.
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
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.
Yep its cool. I have played with sound my whole life. Its fun. All my life i played with big speakers and what sound can do. Its Frequency. You can make things float on sound with big speakers and sound way up. I have done that a whole lot.
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 RUclips.
That is also why pop-pop tin boats move. (Aside from more also very interesting stuff that keeps them running for however long the candle provides enough heat) - Great vid!
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!

Yep its cool. I have played with sound my whole life. Its fun. All my life i played with big speakers and what sound can do. Its Frequency. You can make things float on sound with big speakers and sound way up. I have done that a whole lot.
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. ^^
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.
This guy actually keeps his phones speakers near the candle flame; big respect you ;)
that app blows candles faster than me on my sister’s birthday
I already knew the answer; but, I still enjoyed you explaining it.
God this remind me of being a kid thinking those drink apps were real
me too

It has something to do with flame is a electric conductor (ions) also. Alternating Current also repels a conductor. Speakers use AC to make sound.
Seriously gives that vibe of those apps that make your flashlight as bright as the sun. I was so confused when it actually worked 💀
that is honestly so cool
1:26 man's so rich he's just blowing cocaine around with his phone
!!!
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 RUclips.
When I saw the first part of this video I hurried to check if it was uploaded in April 🤣😂
fire extinguisher been real quiet after this was dropped
Thanks 👌🏼 & can we respectfully appreciate his iPhone speaker could’ve burned just by explaining this

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
Whats the app for android
awesome as always.
That is also why pop-pop tin boats move. (Aside from more also very interesting stuff that keeps them running for however long the candle provides enough heat) - Great vid!
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!
