Yes, the air from the whoopee cushion becomes a medium. But there is also the matter of the apparatus being in contact with the wall of the chamber; some sound gets transmitted that way.
exactly what i was thinking now that i watch this in 2023 the vibration of the apparatus is bangning on the chamber walls which are in contact with air thus creating a sound...
In other words, you can scream in a vacuum, but only those very close to you can hear it.
The chamber is carrying the sound.
one amazing fun show that should of gotten more seasons
3:43
It looks like Adam has a stomach ache.
😂😂😂
Under last breath conditions, sound would only travel as far as your breath could carry it and in space I don't think it would go more than a few inches. That is all based on my understanding of what I learned from Chris Hadfield.
I also think think with the vacume chamber being so small that the air from the inner tube actually went and increased the pressure slightly, which could affect the test, because it would never happen in space.
Exactly, this proves how stupid they are.
That sound would only be carried by contact and the vibration is what you'd feel, not necessarily hear.
For me, the voice sounded still coming from the vibration which the chamber carried
ya they r really stupid...... its the chamber which is vibrating 😔😕
probably still have a higher iq than u, so u can't say they're dumb
isn't this the same result? i mean, if you can touch someone, you can "hear" him screaming . if you connect evry astronaut with a metal wire directly to theyr elmets , they can litteraly hear each other even just talking . so, its not only about vacuum, but you need to have absolutly nothing between you and the person screaming (if the screamer its on a wall and you are on the other side of the wall , you will "hear" him screaming even if the room its in vacuum).
but in anycase, if they expel air, that very air will hit something, since it travel in vacum , so you may be "hit" by the scream , but not realy understand it .
5:03 if your farts sound like that, you should probably get a doctor
from the computer it sounded a bit like one
ImELFY No, it sounded like a motorcycle.
Or the end of the balloon tip was hitting the glass.
Ya and also, doesn’t sound travel through matter and you still make sound in space but the sound doesn’t move, so that’s why you can’t make a perpetual motion machine because of energy being turned into sound energy, and I would think that yes you could potential hear someone in space as long as the sound waves are traveling through mater such as a space suit for example, and I think the cause of the sound being picked up is because of sound traveling through the rods holing the device up.
Andrew Tran, sound isn’t what causes the inability to make a perpetual motion machine. Friction is though, and sound is just an annoying consequence.
Andrew Tran perpetual motion machines don't work because energy can't be created or destroyed just like matter and you turn potential energy into thermal energy, heat.
Sound is sound, whether its the balloon hitting the glass or a scream it doesn't matter. This test is flawed and inaccurate. Space is Vast and this chamber is tiny, under last breath conditions the sound would only carry as far as your breath traveled away from your mouth.
How do I like this comment more than once.
For the last bit, i think everyone is also forgetting holding any breath in the vacuum of space would result in the lungs popping
I absolutely love this guy. Short blond wavy hair, beard and glasses. He is humble and has a sense of humor.
The density of the air coming out of the tube was artificially enhanced, (more dense) by being in a fairly small container, than if it were the vacuum of space. In space I would speculate that the air would be sucked away too quickly.
not to mention the apparatus is touching the chamber walls which can cause vibration.
**Reads title**
Me: If you scream loud enough i suppose. Like imagine how loud Superman actually was speaking in Superman 4.
wasn't that just the balloon flapping against the plexy glass?
I refuse to believe a professional like Adam would make such a rookie mistake. It obviously _looks_ like that, no denying, but it's easy to get fooled by the perspective; it probably looks much closer than it actually was. From those camera angles it's impossible to judge the real distance. But if there ever is a second season of this show they may have a reason to revisit this to sort out the controversies.
Chamber is also vibrating because of the air coming out.
Sound may have travelled through it.
It's the same as if you were close enough to a bomb that exploded but to where you don't get hurt you would most likely here it because of any gas that was trapped in the bomb.
The chamber isn't carrying sound, there's contact in the chamber
If you held your breath during decompression, your lungs would explode.
Then why didn't the tube in the chamber explode? Or at least noticeably expand?
@@agentmikster44 A bicycle inner tube can handle a lot more pressure than our lungs. I doubt the tube was filled with air at the start. It could have been practically flat. There was a bit of editing magic going on, so things weren't exactly as they were portrayed. For example, the tube was more expanded at 3:46 than 4:08, which makes no sense.
You can't save air in your lungs as your lungs completely decompress as you are sucked out of the air lock.
same with sounds like explosions or rocket engines - if the source of the sound also emits a medium that transmits sound you might be able to hear it though it will be very faint and it depends on how that medium spreads out - but an explosion in space may have a much much much much weaker shockwave than in an atmosphere - but there is still hot gas being ejected from the source - if that goes past yo uthen just for a split second you will not be in a total vacuum
Same with a gunshot. I just came from a few comments on an "Always has been" meme.
Umm... without air, sound cannot travel. So in space it‘s impossible to hear a sound and the thing was vibrating.
They said that the breath of the person can carry the sound into space.
Well it can travel through solids and liquids too
Not saying anything bad about the show, and Adam being here is awesome just for the record.
Does anyone else feel that it sucks the original is over and seeing him in this one feels kinda sad?
Adam, you're a very nice person. We love you.
Go back to NASA tank where the is a huge vacuum chamber from the recent experiment Apollo 11
then set up the mic, and the test voice dummy in the sand to reduce vibration, then let's see if it still busted.
it's impossible for the air to move towards someone's helmet to carry the sound of your voice because the vacuum will rip the air apart. (just got the reference from some clips of vacuum releasing pressure)
so im curious as to why an electronic device wasn't used. granted i haven't seen the whole episode but there could have been an entire section devoted to creating a simple battery powered speaker, which you could even modify with a series of resistors so it doesn't constantly produce noise, and would be a useful learning mechanism for logic gates and how computers work. It could even take up 2 sections of commercial breaks with the finale being in a "space vacuum."
edit: ok i get that the myth is a human scream but really the myth is can any sound travel in a near vacuum. (because space isn't a perfect vacuum)
TheRegret or just a whistle
You could have just put a bluetooth speaker to check this phenomena
Once you open this hypothetical airlock into a vacuum, all the air gets blown out of your lungs via the path of lest resistance, so screaming is impossible
my ears were ringing really hard when i was listening OW!
Yeah I feel like they are picking up the sound being transmitted through the walls of the chamber itself and that is why they could not hear it from outside because they were not in contact with the chamber directly.
In space you wouldn’t even be able to hold your breath would you?
plausible because sound needs something to carry it, like are or any mollecule, but in space there is nothing to carry it. so there is no sound EXCEPT vibrations.
The better way that would reduce the flapping vibrations of the whoopie chusion is push the air through an Aztec death whistle. Plus you'd get the sound of a scream which would tell you if the sound changes. Much better test with less varibles.
The arm from the bellows is hitting it's own mounting nut to the motor output shaft.
can you hear a foghorn in space.. yes
that sounded like apple boot up chime on broken speaker :D
Awesome!
is the mic in anyway connected to the inside walls?? I'm wondering if the vibration coming from the last breath contributed to the sounds we heard.
It looks complex for people who know the logic or science behind it ..but it's great video for kids ..it will activate their mind about science which is beyond definitions written in books
I thing the metal supporting that stuff was vibrating and transferring the vibration on chamber and microphone and that's what was recorded or even vibrating the glass. Plus I think Adam explanation could work for that little chamber but in space my shout would travel at sound speed not having time to wait my air moving to the one supposed to hear from me. I think the sound (if any) in the air that I shout out would die before arriving to the other person for moving way faster than the air carrying it
I think it was the vibrations because the rig that they were testing was moving vigorously well they released are
it’s probably just hitting the window
It has a contact with the chamber
Me: can you hear the yodeling kid yodel in space?
Myth busters: “right that down, can you hear the yodeling kid yodel in space?”😂🤣❤️
No the balloon lip was slapping against the cutout
Yes
*Awesome*
You need a bigger chamber. Like the flag on the moon experiment
What if you hit two metal objects together in vacuum
no sound
Uh
Yep
So when a world explode, it's waves, so in reallity. Air, properties and should heat create sound
Cool 👏
1: they really should have used reeds not whoopy cousins, as they produce far less overt motion (flapping around and hitting things) while still producing a very loud noise.
2: their “last breath” solution; it could be argued that they broke the myth. As it temporarily added an atmosphere, therefore eliminating the vacuum.
With the results they show here; I think it really should have been at least plausible.
Could it be the balloon hit the container also the vibrations could also b transferred from the feet of the contraption to the walls of the vacoum chamber
i have a very very simole one, if you can hear sound in space. i bet your ear drum will explode because sun is a continues nuclear explosion.
Wrong. The Sun uses fusion not fission.
agree I do with you yes but your grammar very is not good
The vacuum was gone as soon as air flowed into the chamber from the tube.
just like space...
Awesome☃🤖❄️👻
just a quick thougth
Lets say thiere is a explosion in a ship filled with air shouldent that meant that atleast for a short distanse you can hear in space due to the fact that the air travels out from the ship?
What if farts sounded like that?🙀like someone said you need a docter
That's not a scream it's a fart
In space no one can hear you fart
You can also breathe all the way out then breathe more out then try sceam it
there’s no atoms in space, so it cant vibrate to your ears, and if you could hear in space then you would hear the sun, because the sun is a large explosion. It’s stupid to put this on mythbusters, I learned it in science class;))
Is Adam
Savage gonna be the new Mr. Wizard?
5:19 if you can hear her say 1, shouldn't that be enough?
You speak by vibrations. No air no sound.
Love youuu
the air in your lungs would burst within a few milliseconds so
So a person saying help in space is a fart noise?
Is the explosion of a bomb in space inaudible then?
You might not be built to hear it but that doesn't mean you will NOT feel it hit you
You will hear it. The explosion emits gas, and as that gas passed you, it would vibrate the space suit and the air inside. Thus, you would hear it.
you wouldnt hear it
The sound could have been the rubber hitting the glass
They would've known, it's a production show with many people around it and Adam to theorize all the variables
Well if you could even hold your breath in space. In space your lungs are squeezed like flat footballs and you'll be forced to exhale and you can't inhale so you'd be left to cook like bacon in space and die
Sound doesn't just travel by air, the real question is how fast does a sound wave decay in a Void.
I could never be generated in a void.
doesn’t sound travel through matter and you still make sound in space but the sound doesn’t move, so that’s why you can’t make a perpetual motion machine because of energy being turned into sound energy, and I would think that yes you could potential hear someone in space as long as the sound waves are traveling through mater such as a space suit for example, and I think the cause of the sound being picked up is because of sound traveling through the rods holing the device up.
Also their test is done very poorly because, the cushion that is vibrating is attached to the chamber so then the chamber is vibrating which causes the air to vibrate into the microphone. Order to get a real test they would have to have the cushion suspended on something does not allow the vibration to go into the walls of the chamber.
agreed
in space Everyone can hear You fart. 😆
It not sound it just electrical signal generated when your exhaled air strike microphone signal generating membrane and create electrical signal that are usually due to vibration created by sound wave
Buta Kushwaha what are you even saying....
In space, you only could hear yourself then? like by jaw vibration
Yea, cause there are no molecules in space for sound to even travel
5:46 mongolian throat singers tarts singing
I’ve could probably learn everything by watching this channel🤓
Thank u for liking!😄
9th grade science and Bill Nye says sound can’t travel through a vac, plain and simple
When u don’t know Star Wars:
Paceients my padawon....no it’s patcients young padawon
Well, split second before you say something you take a little air through your nose and then vocalize something.
So since you can't breath in space... the only thing left to do is fart.
Ok, but will anyone be there to hear it. And if so, is it enough to penetrate their helmet?
0:56 not sure which is flatter: this image of earth, or a graph of my patience for your attitude.
0:28 no one got the reference...
Please use speakers
please tell me they build a rocket and went to the moon to test this
WAIT DID THEY SAY MERCURY
There's no point of making the video. If there's no air in space, no sound can be carried.
Did u actually watch the video its about if you can here someone scream and to scream u need to have some air in ur lungs
Untrue. Air isn't always required. The sound can reach your eardrums by other means.
you can hear people scream by using radio
Space is vast, this chamber is tiny, Astronaut Chris Hadfield has already told us that you can't hear anything in space and this test is Flawed. You are better than this Adam.
If you don't have patience you ain't going to be a good mother
Woah---
They made it more complex than it needed to be.
Instead of the motor and whoopie cushion, why not put a speaker in there connected to Bluetooth and have someone yell through their mic?
Or play some Music, whatever the need might be. That way they could check how strong the sound must be to be heard since they know the input.
Though the goal might be to do a test that's mechanical, fun and creative so my argument might be invalid, hehe. :)
The sound of speakers could not be recorded by mic, because sound waves need medium to travel and speakers do not exhale air like human lungs.(here exhaled air works like a medium).
@@amandobhal4264 True.
I did not take notice to that there was air blown ("exhaled") out. Though that kinda ruins the experiment unless that was the exact goal?
I skipped a bit so I might have run over some details.
Either way, this way it seems more like a theory test, as it is not a viable situation that someone exhales out in a vacuum space (imminent death, yeah).
Also their test is done very poorly because, the cushion that is vibrating is attached to the chamber so then the chamber is vibrating which causes the air to vibrate into the microphone. Order to get a real test they would have to have the cushion suspended on something does not allow the vibration to go into the walls of the chamber, making it able to vibrate the microphone and the air around the microphone.
Here is something that none of you noticed. If vacuum should prevent any sounds from being heard why do the mike recording contains Allies countdown? I can come up with two reasons.
1. The sound got transferred to the microphone through the walls of vacuum chamber.2. There wasn't a perfect vacuum and therefore there was enough air in there to transfer sound
But most likely it was the combination of the two combined.
@@silvoweiss347 the microphone was outside the chamber near the pressure gauge as can be seen in 5:26. They were testing if the scream from inside of the vacuum chamber can travel through vacuum (or the last breath of air you expel) into the walls of the chamber then picked up by the microphone :)
I think no
Rachel should play in the stranger things
I don’t have to watch to already know the answer is no.

Sound
Everyone knows the answer to this question. I thought this series was to show that these kids are some prodigies, but this is just for other kids. Not denying that they’re smart and very impressive for their age, just the target audience must be kids.
