Thanks Ben. (Almost didn't recognize you with your new name.) I agree, surprisingly good. The example in the book uses spherical Christmas tree ornaments, the neck being the cylindrical part where the hook attaches to. I tried those too, at a resonant frequency of 523Hz but no movement at all. I suspect I needed more volume but I wasn't willing to turn it up higher in our building.
Thanks. I'm glad you liked it. Be sure and see my follow-up video too then "Why Blowing in Bottles Makes Sound and Helmholtz Resonance" ua-cam.com/video/PZVeJ2rh6ts/v-deo.html And welcome to my channel!
Thank you for your hard work. The video was wicked. Love the vortex rings, and explanation of how it works. Also, great idea showing the book, and the software so I can try it as well! Thanks again!
My pleasure. And thanks for watching. Hopefully I'll be able to figure out how to make a video of the vortex rings. Hopefully the book is right about them being there, otherwise it'll have made me a liar. :)
So to move a rock in this way do you have to hollow it out and make it into the shape of a coke bottle and then blow across the top to get the resonant frequency?
Try asking AI you might get a good answer but I am thinking if it was a solid rock then just get a hard object and hit the rock while use a recording device that can be in contact and press against the rock and record it. More like you press your ear on a cement floor or wall and try getting a harmer and hit the wall. You find that the sound is kinda different compare to when you get your ear off the wall.
This week's vid - moving things with sound, or acoustic propulsion! In this case I use a speaker, playing a 173 cycles per second sound wave, to make bottles propel around. Includes a smoke test so you can see the resulting jet! Enjoy.
Than Zamp It's not working that way. The speakers aren't pushing on the bottle. Each cycle, air from the sound wave enters the bottle starting and enhancing the resonant wave in the bottle. It's the bottle's internal geometry's interaction with the sound waves that is producing the propulsion. So the approach, not feasible since the force is so small, would be to have many bottles around the bottom of the craft like downward pointing jet engines and speakers pointing at the openings of the bottles.
RimstarOrg But the question still stands...could speakers, given enough amplification, lift (if untethered)? We've all stood in front of speakers and have felt the push from the waves...could they in theory be made to produce enough to push off. Additionally, if so, I wonder how they would act in space/vacuum.
Darrell Vogler In vaccum/space, you would need a super speaker capable of working at a power of some thousand gigawatts. And this only after some centuries. And we are still in 21st century. And think for a while. If someone was crazy enough to make a spaceship with speakers, the sounds would kill everyone literally. So no sir, it's impossible *by all means*.
Did you know that with infrasonic speakers and a piece of paper you can actually calculate the infrasound's frequency just by seeing how many times the paper moves in one second? You should do a video on sound, infrasound and ultrasound.
Is it possible to move big things/structures like bigger rocks or megalith with sound? I suspect that ancient egyptians used this sound technique to move megaliths
Great clip! I'd always thought "Find Zero Crossings" was a function like "Show clipping", or "Beat Finder", but but only 'found' them in some other view I wasn't using. I'd not have guessed it had anything to do with selections.
Let's see if you still read comments.... i had an idea concerning the use of resonance and propulsion... this video hits on some of the points... so my thought was to build a resonant cavity and place a tuning fork/rod in the hollow of the cavity and adjust the tuning by extending or retracting the rod into the open cavity from a sleeved regulator that has a striker to set the rod to vibrating... If i were to use this resonance to move air past a few venturi's to cause greater amounts of air to flow over and beneath an airfoil and generate lift without electric motors or propellers or even edfs... What so you think could it possibly work and if so could it be scaled up large enough to move cargo etc....
Never mind.. got it. While pushing it out you get a directed force while sucking in comes from all directions. Additionally get frequency easy using audacity marking the area and menu->analyze->Plot spectrum..->the mouse will snap to the peek and show the exact frequency. You can then generate a clean tone using menu->generate->tone
bitluni's lab Good question re why we have acceleration. The answer's not so simple. It has something to do with viscosity, otherwise it wouldn't move. It's explained, though not too clearly, in the book I mentioned in the video, Notes on acoustics, starting on page 336. But I don't understand it well enough yet. If I can wrap my head around it I may do another video. Re audacity - cool. I'm no audacity expert but I figured there was probably an easier way to do it. However, I stuck with my bare bones approach rather than dig deeper to show it at a more conceptual level and in a way that can be applied with less capable tools (like my video editor.) But you can bet I'm going to use those features now that I know how! Thanks.
Excellent demonstration and very cool. One thing I do not understand...a pulse-jet uses pedal valves to let new air enter the chamber so how does the air get back inside the bottles to once again exit? The entire container is resonating, like squeezing gently and releasing forcing the air out. When/how does new air enter? You videos are always excellent and very thought provoking. Thanks, Bill
The air is entering from the opening and then exiting from the opening each cycle. So that happens 173 times per second with the bottles I used in the video. That's the Helmsholtz resonance. You then say, how can there be a net force? Why is there only the outgoing jet shown by the smoke? According to the book, the jet is actually a bunch of separate vortices and only appears as a jet because the camera is shooting at 30 frames per second. There's also an explanation in the book about how there's a net force, something to do with viscosity, but I've yet to understand it well enough to explain it. -Steve
Net force, exactly what puzzles me. I understand the pulse vortices (too fast for us to see) but not how the outgoing is greater than the replacement air entering the bottles. I will look into this further as it intrigues me. Thanks for your honest answer and for doing the demonstration. Steve, you really are doing some great work over there. Thanks. Bill
My guess is that half might, though I suspect it'd have less of an effect. Not sure about double, since every second wave would be disruptive. I'm not sure I want to bother the neighbors more right now :).
Maybe you could record the vortexes using bigger containers = lower frequency. With a camera in 300fps mode and a 80-100Hz frequency, they might be visible already.
Thanks. My camera does only as high as 60fps but I've already done calculations for container dimensions that bring the resonant frequency down to 57.9Hz. I'm trying that and other things this week. If I'm successful you'll see it in Friday's video.
Here from the Joe Rogan x Giorgi Tsoukalos 2013 podcast after some guys in the comment section were saying that the guy who built Coral Castle claims to have built it by moving materials via harmonics, and that he believes that the ancient Egyptians built their pyramids using harmonics.
Devon Rusinek coral castle was built with dc current. The gentleman whom built it were rock builders from The dark ages so they knew how to melt stone and shape it. Then came dc generator which help them cut stone faster, which old stone cutter technology with dc generators were used to build coral castle day and night. Look it up! Coral castle is not a special place. It’s just old stone workers knowledge passed from generation to generation. The technology never got used in Western Europe till the knights templar. But Templar’s did not know how to melt stone and reshape it. Stone cutting from Egypt has been shown to have organic material in the stone. No normal created stone has organic material in it. So melting stone and making a cement mixture can account for a lot of megaliths.
Good questions. There isn't one directly. The bottle moves in one direction whenever air is pushed out in the opposite direction. So that's the equal and opposite directions there. The speaker has its own equal and opposite directions when the speaker's cone creates the sounds waves, that is the moving waves of compressed air which move up to the bottle's opening. You can see more about how the air in the bottle works in my follow-up video here ua-cam.com/video/PZVeJ2rh6ts/v-deo.html.
Should have put a scale in your string to see if the bottles lose any mass under the vibrations. Other than that, pretty cool experiment you did. Imagine if you had custom flat bottles...
In a normal world, this would be the obvious choice of "fuel" of all vehicles; maybe some alternatives like solar cells and similar stuff..... But .... (Sigh)... Far too many evil mofos live ( unfortunately) who are totally sick in their heart and sick in their brain!!... So... We must continue to suffer. Rant over. See ya!
What if you repeated the experiment? But this time take a aluminum bottle and resonate it at its resonant frequency with unidirectional electromagnetic waves with Pulsed DC with Tesla Coil top load acting like a speaker emitting unidirectional pulses of electromagnetic waves at the resonant frequency of aluminum bottle. Will it work producing some kind of electromagnetic propulsion inside aluminum bottle? Would be interesting project i think figuring out how to get it to work.
Actually I don't want to break it but on the other hand I need a way that not enter external force such as rubbing with finger to it...May you have an idea about this kind of method?!
Hi, thats interesting thank you. The end shot of the smoke coming out the end, reminds me of something i saw on the internet of a super fast, high altitude plane ... ram jet engine. I wonder if this is what they are using?
Nope. Very different technology. Ramjets are almost like regular jet engines found on planes except that instead of using a compressor to compress the incoming air they use the forward motion of the jet to compress it.
The use of sound and resonant frequencies will be the next evolutionary jump in technology. Nice Video. How many amps of electrical input was required?
Sorry but my english is not so good, so i didnt get about the speakers... my question is: what kind of subwoofer should i use to have a result like this... depends also of the bottle´s size??... i would be like to have a nice answer... thanks for sharing! :)
+Jeff Paul You need a subwoofer or a woofer that's good at playing low frequency sounds, around 200Hz or lower. The frequency does depend on the bottle's size. The bigger the bottle, the lower the frequency. But if the frequency is too low, such as around 60Hz, then the propulsion will not be as strong and it might not move. There is a formula for the frequency depending on the bottle shape here en.wikipedia.org/wiki/Helmholtz_resonance.
Hmmm. Good lateral thinking. And here I was thinking of different ways to do strobe lights and if it would work with my camera. The human eyes sees at 30 frames per second (though I sometimes read it's 60.) I just calculated dimensions for a resonator for 57.9 Hz but it remains to seen if it would work in the real world. I had to go with a smaller diameter but longer neck and a larger chamber.
So I see Grant Thompson has already requested acoustic levitation. I second that :P. If you can show me how to levitate a ping pong ball. That will be one less project on the to do list.
My brain is already churning away. As Aaron Stemple is hinting at (I think), nothing large has probably been lifted, but so far I'm thinking it would need a smart array (amplitude control) of surrounding speakers and an active position detection system conceptually similar in idea to what a lot of people do with magnetic levitation. But a first test would be just to see how much force can be produced through constructive interference with a few speakers. That'll tell if it may be doable or not. It won't be through Helmholtz resonance though.
I'm sure I've seen a ping pong ball done with one speaker somewhere, could be wrong though. I have an image in my head of a ping pong ball floating a few inches above a 4" speaker, like one from a car door, or old pc. The Hutchinson effect is done with a very powerful speaker/amp and a microphone to pick up the feedback resonance. Similar in some ways. Falstads has a good open source audio interference applet if that helps www.falstad.com/interference/
RimstarOrg Just spent the afternoon and evening trying to replicate this. Tried my own ideas first and failed. Copied yours, success. I will upload my video later tonight. The Audacity tips worked a treat too. I might try my ideas again sometime but I don't want to upset my neighbors with low frequency sounds late at night :-)
in your sterling engine video you did along time ago I was wondering if it was possible to make the container out of glass. pls tell me I really want to make one :)
I would think no. Typical glass doesn't handle temperature differences very well, and by design that cylinder is supposed to be hot on one side and cold on the other.
@@christianguerra3843 Close. Rapping on the rock will give you a relatively approximate solution. Duplicating this sound without technology is the tricky part, but imagine a few thousand people all drumming to make the same resonant frequency and you're in the ball park.
If the direction of the bottles is reversed, will it spin in the opposite direction? There must be a ring of incoming air within which the output flows.
If the direction of both bottles is reversed then yes, it will spin in the opposite direction. I wouldn't think the air would come from a ring but just from the air surrounding the opening wherever it is at the time air is sucked in, along with the contribution from the sound wave coming from below. But I'm going to make another stab at the explanation the book gives this week. Sadly, the book says the physics of it has never been quantified.
RimstarOrg Well, if the outgoing air is continuous and can be sustained, then there would have to be an incoming flow. The vacuum created would suck air inward. Since I could see the initial blast of smoke and it seemed to be centered on the opening, I was deducing that the inflow might surround that shaft of outgoing air. My curiosity was then going in the direction of determining the overall pattern of the airflow. I'm thinking that perhaps the sound vibration is wrapping around the bottle, compressing the air toward the centerline of the bottle and then out the center of the opening. Imagining this flow, it seems that the only place left for the inflow would be the ring just inside the opening of the bottle. Perhaps if there were a second experiment with a short burst from a smoke source just outside the opening, perhaps just off center. Sorry for going off into all this, but it really piques my interest as to the forced direction of molecules. Why in this pattern?
whereschrism The outgoing air isn't continuous. It only appears that way in the video because the camera is shooting at 30 frames per second. According to the book, the jet is actually a bunch of separate vortices. Since the frequency is 173Hz, there are 173 vortices being emitted each second. During part of each cycle, air is drawn in and then a vortex is emitted out. Even to the naked eye that sees at only 30 frames per second (or is it 60?) it looks like a continuous stream. I'm still trying to understand the book's explanation for the net force.
If you're willing to break it to find out then you can play different frequencies sounds until it breaks. But if you're unwilling to rub it then I guess you're unwilling to break it too.
This reminds me of the older hulk movie with edward norton i believe and they use a machine with some sort of infrasonic frequencies and sound waves to hit the Hulk. Anyone else remember that scene from that movie? Lol
Nope. It's not the sound waves by themselves which make the bottle move. It works using helmholtz resonance which I explain in this video ua-cam.com/video/PZVeJ2rh6ts/v-deo.html
Michael Ta I'm not familiar enough with ihome speakers to say. Check if it produces low frequency audio very well. As I showed in the video, my bottles resonated at around 173Hz and in my experience, bigger bottles resonate at even lower frequencies.
ve tried this with smaller bottles and my studio monitors and 2 gtr amps going up to 101 db spl and nothing. m guessing I need more amplitude, do you have any idea how loud it needs to be to work?
I don't know how many db but it was loud. 100 db sounds about right though. Getting the right frequency is crucial. The smaller the bottle the higher the frequency. I've only tried it with the bottles in the video and bigger bottles. I found that the bigger the bottles the harder it is to get working, probably because the energy is less.
I don't know the thrust of the decibel range. The loudness for me was probably around 100dB, but that's just a guess. It was very loud. I guess you can try calculating the thrust. Weigh a 710ml bottle and get an idea of the acceleration from the video. I tried getting a decibel number from Audacity but I don't see any way of doing it. The volume is turned down in the video I uploaded, but I of course have the original here.
Thanks. :) Depends on which speaker system you mean. The one I showed to explain woofers is my day-to-day one. In that one the speaker's entirely inside the box and has some vents only on the bottom edges - I couldn't get it to work for this propulsion. The one I used for the propulsion I got from our building's trash a while back, along with around 7 satellite speakers. That one's speaker is right on the side facing outward (upward in this video.)
Can we use resonance technology to be able to protect our bodies from being exposed to radiation coming from cellphones, appliances etc. is it possible to deflect radiation from this devices before it reaches our bodies?
this sound sounds super similar to the chants and stuff monks do to levitate amd heal the body. eastern medicine did it first. crazy how much stuff we dnt know that they know that we dnt believe in cuz we grew up in the west and modern big pharma era
@rimstarorg hello I'm sure you have seen the new levitation devices using only speakers with ultrasonic sound...I have been looking for a soundtrack to do such a thing..maybe you can help
I don't know what frequencies they use but you could trying making one from scratch using Audacity, the tool I use in this video. I think Audacity has such a feature.
RimstarOrg hey thank you very much for such a prompt reply...I have never heard of you before this video but I'm going to subscribe to you...thanks again
*"Without vortex-shedding there is no propulsion"* So, this is actually launching a series of ring-vortices, with an intake-cycle between each one. Hey, get a strobe light, set at 172Hz, and you should see the stream of smoke-rings moving slowly out. Heh, JELLYFISH ENGINE! This is how jellyfish propel themselves, using just a single exit-hole as both intake and exhaust.
Back when I was doing this I tried setting my camera frame rate to 60, the best it could do but didn't get good footage. I hadn't thought of using a strobe. Thanks Bill.
Yeah, microsecond flashes would catch them, even if repeated quite slowly. I thought the resonator might be a good way to propel a swimming micro-drone (wireless acoustic power!) Give them two different frequencies, to run each thruster independently via the same loudspeaker. Drive a small camera around inside your own stomach (first drink a couple liters of water!) But it might not work, since at too small a scale, viscosity acts immense, and vortex-shedding doesn't occur. (I hear that bacteria don't exactly "propel" themselves, instead they burrow like moles through water which acts like tar.)
It is pretty cool. :) I'm thinking of doing a video explaining the Helmholtz resonance and it's interaction with the sound waves. That also is cool. Thanks for watching.
Lukas Stankevičius Helmholtz resonance explanation it is then. Though it may take two weeks since I'm thinking of a generic resonance video with spring, swing, Helmholtz and parallel LC circuit as examples. Very ambitious.
Is it possible for you to give me a rough estimate of how loud the was? I'm trying to replicate the experiment but my speaker's maximum amplitude is about 115 dB.
Thank you for your prompt response! I have been unable to replicate the experiment as of now and suspect that my speaker may be the problem. It has a small surface area -- about the size of a 710 ml CocaCola bottle. Could this be the problem? Thanks again!
I'm not sure the small size would be the problem since sound waves spread out spherically from the speaker. If the bottle opening is above the speaker at some point then you should see movement -- if not then that's not the problem. Is your speaker a woofer or subwoofer, like I mention in the video? Woofers and subwoofers are better at producing the required low frequencies. That may be your problem. Another possibility is are you're producing the right frequency. If you're too far off the frequency then it won't work.
RimstarOrg I am fairly certain that I have the correct resonant frequency. The speaker I'm using is not a sub-woofer/woofer so I think that you're right, that may be the problem. You wouldn't say I need more than 115 dB then? I kept worrying that the sound amplitude is not loud enough. Thanks again! I really appreciate your help!
I didn't measure the dB so I can only compare to online charts. The speakers may actually have been producing a lower dB than my estimate since I was in an enclosed room (to reduce noise to the neighbors). In addition to the woofer tip, make sure your bottles are free to move.
Seriously this is one of the most interesting channels on UA-cam.
Nice demo! That's surprisingly good propulsion.
Thanks Ben. (Almost didn't recognize you with your new name.) I agree, surprisingly good.

Really nice experiment. I will give it 9/10 just because no high voltage supply was used that day.
Thanks. Yeah, I do seem to have been getting a lot of use from that power supply. :D
RimstarOrg Hahaha, indeed. Good work.
Can you explain why we have an acceleration? The bottle pushes air out and same amount in again so it's the same mass.
Never mind.. got it. While pushing it out you get a directed force while sucking in comes from all directions.

0:00 Ooooh it just found very similar to the Tibetan long horns which can also levitate small objects.
These are so amazing! I've never heard of this thing.
I wonder if exact double/half frequencies would have same effect.
My guess is that half might, though I suspect it'd have less of an effect. Not sure about double, since every second wave would be disruptive. I'm not sure I want to bother the neighbors more right now :).

Now if we can just make a screwdriver with this technology.
its all possible

(Sigh)... Far too many evil mofos live ( unfortunately) who are totally sick in their heart and sick in their brain!!... So... We must continue to suffer. Rant over. See ya!
Simply wonderful
Could you travel on sound waves would that be an anti gravity way of traveling?
What if your double the frequency? Would it spin faster? And if you divide it but two? I think the vortexes would also puff slower.
What if you repeated the experiment? But this time take a aluminum bottle and resonate it at its resonant frequency with unidirectional electromagnetic waves with Pulsed DC with Tesla Coil top load acting like a speaker emitting unidirectional pulses of electromagnetic waves at the resonant frequency of aluminum bottle. Will it work producing some kind of electromagnetic propulsion inside aluminum bottle? Would be interesting project i think figuring out how to get it to work.
Absolutely brilliant!!!
Very cool I like this my head has more ideas now thank u
Seriously, i never had heard of that. where did you get the idea? that book you mentioned? that was supercool. thanks for posting.
I got the idea from another video, but the book has the details. The other video was just the thing spinning.
Actually I don't want to break it but on the other hand I need a way that not enter external force such as rubbing with finger to it...May you have an idea about this kind of method?!
Nice, real nice. very educational!
Hi, thats interesting thank you. The end shot of the smoke coming out the end, reminds me of something i saw on the internet of a super fast, high altitude plane ... ram jet engine. I wonder if this is what they are using?
Nope. Very different technology. Ramjets are almost like regular jet engines found on planes except that instead of using a compressor to compress the incoming air they use the forward motion of the jet to compress it.
Very nice, thanks for sharing
The use of sound and resonant frequencies will be the next evolutionary jump in technology. Nice Video. How many amps of electrical input was required?
Thanks. Unfortunately, I didn't measure the electrical input.
If the speaker was in a lightweight vehicle can it fly with passengers?
indid simple and briliant those principlesof sympaphetic respnanse
Awesome video! I'd love to see what happens if the cap is on
love it
How much weight can be moved with directed sound?
Good info and video. Thanks 4 sharing
Greets M
That is great! What frequency would it need to levitate heavy items to the air?
I'm not sure that can even be practically done. However, I do know that higher frequency means more thrust.
What is the effect of sound wave on the ether?
Fantastic, thanks for sharing.
Sorry but my english is not so good, so i didnt get about the speakers... my question is: what kind of subwoofer should i use to have a result like this... depends also of the bottle´s size??... i would be like to have a nice answer... thanks for sharing! :)
+Jeff Paul You need a subwoofer or a woofer that's good at playing low frequency sounds, around 200Hz or lower. The frequency does depend on the bottle's size. The bigger the bottle, the lower the frequency. But if the frequency is too low, such as around 60Hz, then the propulsion will not be as strong and it might not move. There is a formula for the frequency depending on the bottle shape here en.wikipedia.org/wiki/Helmholtz_resonance.
cool!
Thanks!
Very cool. Could you tune the chamber to a resonant frequency that would generate a visible train of vortex rings?
Hmmm. Good lateral thinking. And here I was thinking of different ways to do strobe lights and if it would work with my camera. The human eyes sees at 30 frames per second (though I sometimes read it's 60.) I just calculated dimensions for a resonator for 57.9 Hz but it remains to seen if it would work in the real world. I had to go with a smaller diameter but longer neck and a larger chamber.
Maybe PVC of different diameters and lengths with some reducing fittings? Let the theory get you close and finish the tuning with a hacksaw?
very cool. informative, concise and oh yeah, AMAZING!! thanks,,
feefiefofanna stfu
And your experiment is pretty interesting
Well done !
Thanks Stefan!
Good, it gives many unknown answer
if i divided and divided repeatedly any object mass weight on earth again and again until then, i get 6.67 x 10^-11 Nm/kg this is Gravitational fields
I tried it with a 2 later bottle and it looks amazing
Cool. What was the resonant frequency?
So I see Grant Thompson has already requested acoustic levitation. I second that :P. If you can show me how to levitate a ping pong ball. That will be one less project on the to do list.
My brain is already churning away. As Aaron Stemple is hinting at (I think), nothing large has probably been lifted, but so far I'm thinking it would need a smart array (amplitude control) of surrounding speakers and an active position detection system conceptually similar in idea to what a lot of people do with magnetic levitation. But a first test would be just to see how much force can be produced through constructive interference with a few speakers. That'll tell if it may be doable or not. It won't be through Helmholtz resonance though.
I'm sure I've seen a ping pong ball done with one speaker somewhere, could be wrong though. I have an image in my head of a ping pong ball floating a few inches above a 4" speaker, like one from a car door, or old pc.
The Hutchinson effect is done with a very powerful speaker/amp and a microphone to pick up the feedback resonance. Similar in some ways.
Falstads has a good open source audio interference applet if that helps www.falstad.com/interference/
Brilliant!
Thanks!
RimstarOrg Just spent the afternoon and evening trying to replicate this. Tried my own ideas first and failed. Copied yours, success. I will upload my video later tonight. The Audacity tips worked a treat too. I might try my ideas again sometime but I don't want to upset my neighbors with low frequency sounds late at night :-)
GrandadIsAnOldMan
Looks good! I like that you included what didn't work too.
That's pretty cool, and something you can do without a HVPS.
Yup! No HVPS. You have no excuse not to try it now! :)
in your sterling engine video you did along time ago I was wondering if it was possible to make the container out of glass. pls tell me I really want to make one :)
I would think no. Typical glass doesn't handle temperature differences very well, and by design that cylinder is supposed to be hot on one side and cold on the other.
Amazing ... How can I get the resonance of a rock?
Wessam Raafat we need ask this for old sumerians or the guys in puma punko in Bolívia buddy.
Depends can you smell what he's cooking
*smack it against your forehead*
@@christianguerra3843 Close. Rapping on the rock will give you a relatively approximate solution. Duplicating this sound without technology is the tricky part, but imagine a few thousand people all drumming to make the same resonant frequency and you're in the ball park.
Thanks for sharing! As usual - amazing ^^
My pleasure. Thanks for watching!
If the direction of the bottles is reversed, will it spin in the opposite direction? There must be a ring of incoming air within which the output flows.
If the direction of both bottles is reversed then yes, it will spin in the opposite direction. I wouldn't think the air would come from a ring but just from the air surrounding the opening wherever it is at the time air is sucked in, along with the contribution from the sound wave coming from below. But I'm going to make another stab at the explanation the book gives this week. Sadly, the book says the physics of it has never been quantified.
RimstarOrg
Well, if the outgoing air is continuous and can be sustained, then there would have to be an incoming flow. The vacuum created would suck air inward. Since I could see the initial blast of smoke and it seemed to be centered on the opening, I was deducing that the inflow might surround that shaft of outgoing air. My curiosity was then going in the direction of determining the overall pattern of the airflow. I'm thinking that perhaps the sound vibration is wrapping around the bottle, compressing the air toward the centerline of the bottle and then out the center of the opening. Imagining this flow, it seems that the only place left for the inflow would be the ring just inside the opening of the bottle. Perhaps if there were a second experiment with a short burst from a smoke source just outside the opening, perhaps just off center. Sorry for going off into all this, but it really piques my interest as to the forced direction of molecules. Why in this pattern?
whereschrism
The outgoing air isn't continuous. It only appears that way in the video because the camera is shooting at 30 frames per second. According to the book, the jet is actually a bunch of separate vortices. Since the frequency is 173Hz, there are 173 vortices being emitted each second. During part of each cycle, air is drawn in and then a vortex is emitted out. Even to the naked eye that sees at only 30 frames per second (or is it 60?) it looks like a continuous stream. I'm still trying to understand the book's explanation for the net force.
One question,how can I measure resonate frequency of wine glass without entering any forces,such as rubbing the rim of it.Thanks.
If you're willing to break it to find out then you can play different frequencies sounds until it breaks. But if you're unwilling to rub it then I guess you're unwilling to break it too.

This reminds me of the older hulk movie with edward norton i believe and they use a machine with some sort of infrasonic frequencies and sound waves to hit the Hulk. Anyone else remember that scene from that movie? Lol
It’s not just sci-fi in movies.. nasa uses sonic drilling for core samples..
what if u turn woofer upside-down towards the floor? can u find the freq to levitate woofer above ground??
Nope. It's not the sound waves by themselves which make the bottle move. It works using helmholtz resonance which I explain in this video ua-cam.com/video/PZVeJ2rh6ts/v-deo.html
What happens if you use the half frequency (ca. 86 Hz) so the first harmonic would be around 173 Hz?
I suspect it would work but I didn't try the harmonics or subharmonics so I can't say for sure.
Great job i'll try some like you did :)
I can't get my set up to turn. How many decibels are you using?
I didn't measure the decibels and don't have any way of doing it. But it was quite loud, you could barely hear yourself speak over it.
do you have to use a subwoofer. can you use a regular ihome speaker?
Michael Ta I'm not familiar enough with ihome speakers to say. Check if it produces low frequency audio very well. As I showed in the video, my bottles resonated at around 173Hz and in my experience, bigger bottles resonate at even lower frequencies.
ve tried this with smaller bottles and my studio monitors and 2 gtr amps going up to 101 db spl and nothing.
m guessing I need more amplitude, do you have any idea how loud it needs to be to work?
I don't know how many db but it was loud. 100 db sounds about right though. Getting the right frequency is crucial. The smaller the bottle the higher the frequency. I've only tried it with the bottles in the video and bigger bottles. I found that the bigger the bottles the harder it is to get working, probably because the energy is less.
thanks, ill keep trying
Do you know anything about how much thrust this has and what decibel range you are using.
I don't know the thrust of the decibel range. The loudness for me was probably around 100dB, but that's just a guess. It was very loud.
I guess you can try calculating the thrust. Weigh a 710ml bottle and get an idea of the acceleration from the video.
I tried getting a decibel number from Audacity but I don't see any way of doing it. The volume is turned down in the video I uploaded, but I of course have the original here.
ok I gotcha. Thanks
Cool! And I think we have the same speaker system
Thanks. :) Depends on which speaker system you mean. The one I showed to explain woofers is my day-to-day one. In that one the speaker's entirely inside the box and has some vents only on the bottom edges - I couldn't get it to work for this propulsion. The one I used for the propulsion I got from our building's trash a while back, along with around 7 satellite speakers. That one's speaker is right on the side facing outward (upward in this video.)
RimstarOrg
Yeah I meant the 7.1 system, whose subwoofer you use
that was cool !
Thanks Tom. I agree. Don't know if my neighbors agree though (noisy). :)
Does anyone have a source for a resonance shape / chamber for 7.83hz
Can we use resonance technology to be able to protect our bodies from being exposed to radiation coming from cellphones, appliances etc. is it possible to deflect radiation from this devices before it reaches our bodies?
Built a Faraday cage!!!
this sound sounds super similar to the chants and stuff monks do to levitate amd heal the body. eastern medicine did it first. crazy how much stuff we dnt know that they know that we dnt believe in cuz we grew up in the west and modern big pharma era
@rimstarorg hello I'm sure you have seen the new levitation devices using only speakers with ultrasonic sound...I have been looking for a soundtrack to do such a thing..maybe you can help
I don't know what frequencies they use but you could trying making one from scratch using Audacity, the tool I use in this video. I think Audacity has such a feature.
RimstarOrg hey thank you very much for such a prompt reply...I have never heard of you before this video but I'm going to subscribe to you...thanks again
Ran into this on a google search. always wanted to do stuff like this. Just never got there.
could it work on WATER ? as a propulsion system?
The bottles alone could probably push a small toy boat but you'd also have to carry along the heavy speaker so I'm guessing not.
Hello, I hope your still alive, and willing to answer a question of mine. Does the thing blow out air more, than air intake?
It runs continuously so no.
BTW I talk about how it works in this follow-up video ua-cam.com/video/PZVeJ2rh6ts/v-deo.html about Helmholtz resonance.
Pretty cool experiment. =)
*"Without vortex-shedding there is no propulsion"* So, this is actually launching a series of ring-vortices, with an intake-cycle between each one. Hey, get a strobe light, set at 172Hz, and you should see the stream of smoke-rings moving slowly out.
Heh, JELLYFISH ENGINE! This is how jellyfish propel themselves, using just a single exit-hole as both intake and exhaust.
Back when I was doing this I tried setting my camera frame rate to 60, the best it could do but didn't get good footage. I hadn't thought of using a strobe. Thanks Bill.
Yeah, microsecond flashes would catch them, even if repeated quite slowly. I thought the resonator might be a good way to propel a swimming micro-drone (wireless acoustic power!) Give them two different frequencies, to run each thruster independently via the same loudspeaker. Drive a small camera around inside your own stomach (first drink a couple liters of water!) But it might not work, since at too small a scale, viscosity acts immense, and vortex-shedding doesn't occur. (I hear that bacteria don't exactly "propel" themselves, instead they burrow like moles through water which acts like tar.)
Great vids!
very interesting video...
magic
That's just amazing.
It is pretty cool. :) I'm thinking of doing a video explaining the Helmholtz resonance and it's interaction with the sound waves. That also is cool. Thanks for watching.
Helmholtz resonance video would be interesting.
explanation is that would be great now
Lukas Stankevičius
Helmholtz resonance explanation it is then. Though it may take two weeks since I'm thinking of a generic resonance video with spring, swing, Helmholtz and parallel LC circuit as examples. Very ambitious.
Wow nice!
I'd like to see a rc boat of this or something like that!
Rimstarorg what about acuastic levitation in 3d space??
I'm planning on looking into it and giving it a try.
That's really cool!!! :D
Is it possible for you to give me a rough estimate of how loud the was? I'm trying to replicate the experiment but my speaker's maximum amplitude is about 115 dB.
A rough estimate by looking at charts online, I'd guess at between 100 and 120. It's too loud to hear yourself talking, you have to shout.
Thank you for your prompt response! I have been unable to replicate the experiment as of now and suspect that my speaker may be the problem. It has a small surface area -- about the size of a 710 ml CocaCola bottle. Could this be the problem? Thanks again!
I'm not sure the small size would be the problem since sound waves spread out spherically from the speaker. If the bottle opening is above the speaker at some point then you should see movement -- if not then that's not the problem. Is your speaker a woofer or subwoofer, like I mention in the video? Woofers and subwoofers are better at producing the required low frequencies. That may be your problem. Another possibility is are you're producing the right frequency. If you're too far off the frequency then it won't work.
RimstarOrg I am fairly certain that I have the correct resonant frequency. The speaker I'm using is not a sub-woofer/woofer so I think that you're right, that may be the problem. You wouldn't say I need more than 115 dB then? I kept worrying that the sound amplitude is not loud enough.
Thanks again! I really appreciate your help!
I didn't measure the dB so I can only compare to online charts. The speakers may actually have been producing a lower dB than my estimate since I was in an enclosed room (to reduce noise to the neighbors).
In addition to the woofer tip, make sure your bottles are free to move.
