I'm a big fan of yours, hoping to learn more :)
Quality ALSO Quantity.
RAID, no!!! 😒
commenting to feed al gore, not clicking your sponsored link though, never bothered with rsl before and it didnt look good :(
That's really cool
The big speaker which had the tube in it actually has a helmholtz resonator, the tube. It is used to boost The low frequencies. It is also called a bass reflex port.

@@chocho6766 so he’s selling his viewers to a bad company for his own profit. Not a bad thing at all
@@brandonm1708 The app is free and you can just skip that part so i dont think its that bad
@@brandonm1708 and the viewers have a choice to use it or not?? what's the problem
Next, teach RUclips to power their notifications by sound
Wut?
That would be annoying.
Absolutely correct

I caught myself asking a dumb question. As I was watching the video, I thought to myself:"I wonder if this could be applied to space travel?" No doubt some of you will see the problem much quicker than my 64 year old brain did. "D'uh, sound doesn't work in a vacuum!" I claim no liability for any injuries sustained during face-palming.
Thanks, Action Lab, for educating this old dog.
There's also no air 🤦
Most definitely can be used for space travel... think of it like this... a machine that can displace particle Mass behind its self as it travels forward... where you have that 50/50 balance. Once you have achieved that 50/50 balance you can go anywhere in size and time... but "not" in space and time. This is all that I can say at this location & point in time. Because of a certain separation factor between the "God of Love" & the abomination of desolation and or that which makes desolate. Seek the light and most definitely you will be allowed to step into the kingdom of heaven... for the "God of love" is planting its kingdom on this earth at this point in time !!!
@@gordonstull1962 lol 😆 and then the easter bunny will cure everyone's cancer, the tooth fairy will spread her legs for me, and santa clause will watch.
God (and religion in general) is just a construct created by humans to make humans behave. Without it there would be nothing stopping anyone from stealing and killing for personal gain, and further evidence isn't hard to find: ever wonder why no religion mentions dinosaurs? Seems like a huge part of earth's history to forget.. well it's because religion was created by man BEFORE the discovwry of dinosaurs, so of COURSE it wouldn't be in any religion.
There is no god, and if there is he stopped caring about this forsaken rock almost 2 thousand years ago.
@Jake Loranger It could! Just not with air but with a flow of ions in plasma or Hall thrusters. Although I don't know if the linear propulsion they use would provide a stronger push than just the flow eddies. But you certainly need to account for non laminar flow when designing the thrusters. Maybe you could even make use of it, like ducks do by flying in a V. (Although you don't have sound in space so you wouldn't be able to make the object vibrate like this. But the turbulent flow does apply here.) At least that's what I'm thinking. Great question!
@TriVos Ahren no sound, but what about memes?
I'm learning more from this than I've learned from online schooling the last few months
He’d be a really cool science teacher
Sad but true :(
I wish he was my science teacher I dont care about math but with him i LOVE IT!!! He somehow makes school fun!!
Totally agree with you 😂😂
I am learning about waves right now and this video might be useful which is cool.
"powered by sound"
That one girl in class when the power goes out: UNLIMITED POWER!
I was taught that the air in the neck of a Helmholtz resonator acted like a mass and the air in the body acted like a spring - essentially just a mass-spring system. The smoke demo reminded me that reality is much more complicated. Very cool idea.
Right as if the air in the neck of the bottle virtually never leaves that location, and just moves up and down.

I love your videos, you answer amazing questions that I’ve never thought of.
Action lab man, you are amazing.
I'll be honest
I learnt more science by watching channels like these than school textbooks
Same
Ya school sucks
Me to
School text book teach the basics. This is more advanced, something you would learn in college
@@thecommenter578 so i guess i learnt college stuff in school
Your channel is better than most public school science teachers. You shouldn't have to plug Raid Shaddow Legends
Omg thank you for explaining the car window down noise!! I always wondered why that happened and now I know it’s this helmholtz resonance!! 😱
Love your Videos, keep up the great work!
As a musician this is really really cool! I notice a similar thing happening with certain frequencies with the snare wires in a snare drum. If you hit a certain frequency they’ll start to resonate really fast!
Great job!!!! ANOTHER wonderful video! Love the scientific principles in our everyday objects that I had no idea about. Thank you so much, keep it up!
Action Lab : Moving object using sound
Me : that's 'sounds' easy
😁😁😁👍👍👍
Also Action Lab: 0:05 sounds easy
This was a VERY cool and interesting video, brother. Thank you for continually making great content like this. :)
I love learning new things I didn’t know about, he really does make it easy to understand, like a lot, keep up the videos!! I love em all!!
Love your channel man. Keep up the good work.

That is a cool demonstration of resonance ! loved it ! thanks.. I love your channel.
Thank you for teaching us science in such a didactic way
You really do amazing things with everyday materials man! cheers!
Hi I love your videos they teach me a lot and thank you for teaching me things in a cool and fun way
Thanks, man.
Now I can move objects with my sound.
Very nice video - a subtle effect, I have learned something new.
great work..
nice research on sound
keep up the good work💞👍
I learned more about waves on a ten minute RUclips video than the whole high school.
Edit: There are a lot of Einsteins and trolls under the replies. You have been warned.
It's all fun and games till he got to teach maths behind it
If that's the case, you probably weren't paying attention on physics lessons.
Thats depressing
True
@@outandabout259 my school didnt teach us anything about waves in physics but instead in biology and we got a month of it but atleast they also teached us about how light works. They changed the curriculum and now they learn it in 7th grade physics in the last two weeks of school only learning about sound waves and thats the only time they teach it in all grades.
*_'I used a champagne bottle and the bottle sounds like a weird instrument!!'_*
This one Literally taught me so much, thank you man!
This is really cool! Reminds me a little of the rice on the speaker that creates different shapes based on the frequency.
This video is a perfect segway to the backpressure argument in vehicle exhaust systems (and this is also my attempt at a free engineering analysis for the best exhaust setup for my Mustang).
You never cease to amaze and enthral. Your videos make my mind happy. Well done.
That is cool. Great explanation and demonstration.
Thanks, this was really interesting!
This was great, i never knew that, so glad i watched this.
An interesting video and really clear explained!
I wish u were my science teacher back when I was in high school, ur videos are so incredibly interesting
Nice video, great job showing how it works.
Excellent demonstration.
Omg i was studying about sound energy in physics just an hour ago and he made a video on it
We just finished a unit on waves
Awsome video! muchas gracias
@The Action Lab the fluid dynamics community would point out that this is a reaction motor, similar to a pulsing jellyfish creating propulsion by flinging out vortex-rings. Vortices slowly carry momentum along as they move. (A mass-bearing fluid jet is the same as a close-spaced stack of moving vortex-rings. But launching even one vortex-ring will give an opposite "kick" to the launching device.) If your fluid viscosity is low, then, during sound-oscillations at a circular aperture, the "sucking" part of the AC cycle will produce no vortex-shedding and zero propulsion, but the "blowing" will assemble and launch a single ring-vortex, which carries momentum with it as it flies away. So, rather than a von Karman vortex-street, it's "smoke-ring machine-gun." (But multiple vortices are not required. A single ring-vortex is a mass-carrying object, and the bottle receives a "kick" from launching each single ring-vortex.)
Maybe with an ENTIRELY smoke-filled bottle, aimed upwards, a high-speed camera might see ring-vortices in the smoke stream, just before clear air gets injected into the bottle and messes up the uniform smoke. (Probably there are ring-vortices being launched inwards as well. But these crash into the bottle's inner surface, delivering their momentum back into the bottle, so they produce zero net thrust.)
It's just a jet engine, but where the intake and outlet are the same. It must rely on "Feynman's Inverse Lawn-sprinkler" effect, where sucking does not shed any vortices, and cannot cause propulsion, but blowing causes large propulsion. Hence, oscillating AC fluid-motion will still generate a narrow "exhaust plume" and create a reaction-motor for Feynman's sprinkler (but only in situations with high fluid inertia and low viscosity.)
Vortex-rings have an outer surface! They're roughly spherical. All the air within the surface is moving along as the entire vortex moves ...as if the vortex was a moving baseball made of gas. It's a real "object," just like a fluid jet, and if it strikes a surface, it delivers a punch. (And when you first create such a gas-baseball, your vortex-launcher receives a "reaction kick.")
Here's something I've yet to try. Build a loudspeaker-based smoke-ring box. Put it in an aquarium full of smoke. Now launch smoke-rings upwards slowly. Ideally they should be spherical, like "Hills Vortex." WIthout turbulent mixing with the air outside the spherical boundary, the ring-shaped flow in the core may be totally invisible. Will they remain as "air balls," and not slowly change back into smoke rings?
edit: hey, RIMSTAR has a 2014 video, and his shows a textbook illustration: yes, the stream is actually individual smoke-rings, NOT a von Karman vortex-street. His yt video is: L5fVFA2sWt4
Awesome vid literally my role model
you are just amazing thanks for increasing our knowledge brother
When I worked in Hospital, we used a resonator to calibrate the output power of therapeutic ultrasound devices.
The resonator is immersed in water, the transducer in water a set distance away.
The pointy end of the resonator (sealed!) was facing toward the transducer.
As we increased the power, the resonator would be pushed back...the amount of deflection a direct measure of 'acoustic pressure'.
Oh, the water had to be pure and a certain temperature, but the results of the test were considered reliable.
Wow I loved it good job
Nice concept 😍
you have a lot of interesting videos, but i think this is my favorite yet.
I really like your videos, thank you
Good stuff!
Wow, this is fascinating and cool! 😀👍🏻
This is mind blowing. I love his content
I use to get bored in the class when I studied but now I'm here watching your RUclips videos after years I graduated 😂
Great expriments ,Love your videos .
Please make more of such interesting videos for us Science nerds.
When action lab posts my day is made
That sponsor transition killed me lmao
Good work.
8:19 Sounds like the first note of “Welcome to Los Santos” 😂😂 I could’ve sworn it was gonna start playing
Fantastic idea
A critical key to think about is the squareness of volume... an over square vortex tends to become trapped between two pressure gradients and un-coils itself, where as a under square vortex is able to free itself through the process of coiling inwardly . Expansion chambers like what was used on early 2-cycle dirt bikes moved the exhaust gases out the end of the expansion chamber in that a vacuum could be created on top of the piston & at a time when the piston was at bottom dead center and again, produced a pressure when the piston started it's way upwardly. Engery that is transmitted by sound is greater when a gas is under pressure than what it is under a vacuum.
Just BRILLIANT ! brilliant explanation really. No one does it so well on the web . Very intersting even becasue of the analogy such a topics can propel.WELL DONE thank you.,
Awesome upload
You picked the best choice speakers 👏
Hey man, that was really cool.
When I saw your wave machine I was like, who has that?! and then when I saw the left half, with the other types of wave, I was like WOAH! I want one!
@6:38 I think it is in part because of the vortex explanation, but I also think it would work without vortex shedding on the outgoing air too. The reason is because the air exiting the bottle is relatively directed straight out but the incoming air is drawn from air in all directions near the opening, creating less directional momentum.
Really cool!
This is absolutely wild man 😯
My total guess is that there's an air impedance mismatch between incoming and outgoing air, as well as a direction difference. It's picking up air from around it (omnidirectionally) at lower velocity, while thrusting it (unidirectionally) at a higher velocity with a narrower stream. So there will be no net difference in incoming vs outgoing air, just a difference in impedance and direction. Vortices are amazing!
Im 30 years old and until now never understood how to imagine sound waves. Thank you!!!
this is very epic
Now this
Is a poggers moment
At this point it's a rite of passage to have the Raid sponsorship. Well done! Great experiment as well!
I did not know that. Very interesting!
Where do you get your content ideas!?!? Nice vid
More Sound Experiments please!!
My teacher is teaching exactly this topic at college got chance to see practically as well❤️
the anount of knowledge this man possess is phenomenal.
did I ever tell you....I love your channel and thank you!!!!
I wonder why you don’t have 10 million subscribers already. Your videos are awesome. Every single one of them
You explain a lot better than my teachers😊😁
wow l love it, very interesting
Awesome!
Very interesting! Would have been interesting to see the smoke at different frequencies.
Awesome 👌
This channel continues to impress me! I liked everything discussed in today's video... Wow! I've seen the wave simulator before, but never saw the longitudinal portion of the demo... it reminded me of FM (Frequency Modulation) propagation (vs AM that is transverse). Now for a jumble of questions and ideas... bear with me please... what occured to me is that it might be possible to shape the sound to make things move?? I Googled and found out that there such things as standing longitudinal wave with sound... Can those waves be swept to create motion? On a similar note... I've seen a demos of interference sound waves by using a second sound wave to create NULLs then sweeping one frequency would move the nodes thus any object that was positioned in the null would follow it and thus move. And one more thing: I've seen a really cool demo (I think using 3 ultrasonic transducers) to levitate and move small objects in 3D space.
That car part was cool, I always wondered about that
that wave machine looks so satisfying 🤣
First subbed u when you had 200k

This is actually what ducks and other big migratory birds do flying in a V shape. They use the momentum of the little eddies of flowing aur made by the batting of their fellow birds, to conserve energy. So cool!
