Rockets in a Vacuum Chamber – Newton’s third law of motion Visualized

January 28, 2020

Everybody ready. 321. No. Welcome back. After watching some Flat Earth videos. And conspiracy theorist. This stuff started getting into my head. So this time I’m going to legitimately challenge
Newton’s third law. To demonstrate is it a law or a lie. So I set out to build a bigger better vacuum
chamber. That’s going to give us undeniable results. I am genuinely curious as to. How Newton’s third law is going to behave
in the environment of a vacuum. We’re in this case. The Rocket won’t have an atmosphere to push
against. Alright we got our vacuum chamber completed. The only thing I have left to do is get the
top seal on. Get the top cover in place. And test it. In order for this experiment to give us reliable
results. I contacted the AIAA team at UIC. Turns out they have some solid rocket propellant. On hand ready to go. So I headed it down to their lab. Which was a very interesting place by the
way. They gave me. Not only the solid rocket propellant. Is this the actual propellant?. I thought it would be heavier than this. Feels kind of light. This is our solid rocket right here. But everything else that I need. To build a miniature version of a solid rocket
booster period similar to what Nasa uses. I believe this is going to give us more concrete
results. Not based off of black powder rockets. That well. Nobody Burns in space in the first place. Now that I have the vacuum chamber built. This vacuum chamber is going to allow me. To pull a complete vacuum. But before moving on to the experiment. I want to do some initial testing. to make sure that this vacuum chamber is safe
to use. And that it holds the vacuum. Make sure we don’t have any leaks or anything
like that. So let’s test it out. Perfect. First and foremost since Motors produce
a lot more thrust. Then the black powder Motors I used in the
previous episodes. I had to come up with a better way to mount
them. In the vacuum chamber. This is what I came up with. This is like against all possible rules. The team even named it the four legged spider. Hold on. That’s a different movie. Second and most important we need to measure
thrust. This is going to be our thrust scale. I think for this I’m going to go low-tech
old school. I have a feeling that the team was quite impressed. Oh is that what we’re using. With my practical approach to this problem. That’s pretty good that’ll work. Now that I have all that figured out. It’s time to assemble our rocket motor properly. Mount it in the vacuum chamber with the scale. To measure the thrust. And run our chamber through the first partial
vacuum test. Hang on it’s vacuuming down. I would give it one more second then hit it. Hit it hit it go. Go. Perfect it all happened so fast. So we know Rockets burn. I’m going to install a new rocket motor in
the casing. This is our nozzle and our nozzle retainer. Reset the experiment. And only one question remains. Sir Isaac Newton does your law still apply. Over 330 years later. In a vacuum ?. Well I hope you’re watching
because. We’re about to find out. Alright we got our blast shield in place
for safety. Our vacuum chamber is in a vacuum. Are rocket is set wired up and ready to go. And yeah I’m excited. The only thing I have left to do is take these
two wires. Touch them to the terminals on this battery. And hopefully it doesn’t go boom. Hopefully it just goes Swoosh. Everybody ready here it goes. What a Hang Fire no Not a Hang Fire. No freaking way you got to be kidding me. So apparently I have some findings from the
first phase of the experiment. And that is I just realized that the vacuum
has now created an environment. Where it becomes more difficult to ignite
the solid rocket booster. This means that there is some truth to what
the conspiracy theorist think. It’s more difficult to ignite a solid rocket booster in
a vacuum. Because we tried this in atmospheric pressure
and it ignited just fine. I mean that’s definitely an interesting finding. I have just one more problem. Due to the rapid depressurisation of the chamber after that
last attempt. One of the seams was compromised. I need to re-weld that seem. And put in a couple of supports where the
deflection occurred. That demonstration gives you an example of
just how much force. Pulling up vacuum in a chamber like this has. It’s essentially at sea level 14.7 PSI. which
is 14.7 lb for every square inch pushing in on each side of this chamber. So if you do the math which I already did. It’s about 80,000 pounds combined. So you have 20,000 pounds on each one of these
walls trying to cave this thing in. Since that last attempt was a failure. I invited the AIAA team over for the rest
of the experiment. Because I know how much they love hangfire’s. And they have a lot more experience with this
propellant than I do. In case I run into any more issues along the
way. So pretty much all of that smoke that came
out was the ignitor nothing else. And I think they’re in for a big surprise. Because I don’t think it’s going to be that
easy to ignite in a full vacuum but we’ll see. Alright I would hit it now, 321. Ooooh. Ooooh. There you go, that is the problem we’re having
all along. What do you think Mike?. We can repack and ignitor and try it again. Looks like we may need some atmospheric pressure
in the actual booster. To get it to ignite. Once it’s ignited I think it’s going to do
okay. What do you think Mike?. we’ll try it again It could be from the lack of air, from the
type of ignitor, from the cap being on it, hard to say. So do you think once it’s lit in a vacuum
it’s going to stay lit?. It should it’s got its own oxidizer. Let’s see what it looks like. All that smoke. And it looks like the igniter kind of ignited
right. Yeah it definitely did. look at that it kind of ignited but it
doesn’t look like it fully ignited. This is going to be our second attempt. We have another igniter in place. What do we do differently this time?. We changed out with a completely new motor. This is the old one that we just test fired. Yeah I don’t think the motors the problem
though I think it’s the vacuum. We will try and see what happens. That’s a brand new motor and a brand new ignitor. We doubled them up this time, alright,
I’m feeling good let’s do it . 3-2-1 go go go. Oh no it failed. go go go oh no it failed. No more power right, no. That was very strange. This was our 3rd attempt here and it was a
failure as you saw in the footage. My recommendation is. These guys didn’t think that this was going
to be a problem, I did however. I called it I said this thing may give us
issues to light. So the next thing that I suggest is I think
we should seal it up. I’m going to modify this rocket motor. I think once it’s ignited it’s going to create
some internal pressure and keep burning. But that’s not what I’m challenging here. I am challenging Newton’s Laws. I want to see if when it burns in a vacuum. If it creates a reaction that produces thrust. So this is our fourth attempt and what we
did different this time. Is we made a ruptured disc on the outside
of the nozzle. And this is going to hold atmospheric pressure
on the inside the motor until ignition occurs. And the idea is this thing is going to pop
out. And the motor is going to light Ignite and
burn normally. That’s the key word burn normally. our solid rocket motor burned in a vacuum. As you can see that was a success. Not only that are solid rocket motor burn
in a vacuum. But it also produced thrust. During those initial moments of ignition. Which is exactly what I was looking for
to support Newton’s third law. Because any thrust produced under these conditions. Is produced off of the pure reaction of the
fuel burning. And not from the thrust pushing against air
or an atmosphere. Now something that I found really interesting. Was where the main ignition occurred. If you look closely at the high-speed footage you can see The majority of the gas started to ignite
in the vacuum chamber. Not right behind the rocket motor as I would
expect. I’m not sure why that is but that looked pretty
cool. Regardless of our gauge readings for our vacuum
chamber. The vacuum was obviously sufficient. Because this was our fourth attempt. We had to modify the rocket motor in order
to get it to ignite in the vacuum chamber. That being said I’m just going to do one more
experiment. I’m going to get a really small model Rocket motor. 1/10 the size of this solid rocket booster. And put it in this same chamber. What that’s going to do is essentially increase
the amount of volume in our chamber by 10. Since that motor is 1/10 the size of this
motor. And this Burns a little bit slower than a
solid rocket booster. We’re going to be able to see whether or not
it’s creating thrust in a vacuum. And that’s going to further validate Newton’s
third law. Alright here goes. Okay so that was another successful burn. The model rocket motor burned just fine in
the vacuum chamber. Unfortunately it didn’t go exactly as planned. Because the sled got wedged in between the
walls of the chamber when I pulled a deeper vacuum. But if you look closely at the motor when
it first ignited It produced some thrust. And it pushed itself into the casing of the
motor where it was being held. That to me further supports Newton’s third
law. Apparently it applies in a vacuum as well
as atmospheric pressure. Yeah I think that was enough proof for me. Hopefully you enjoyed this episode. feel free to share, subscribe, tell me what
you think in the comments below. This was a tough one. This was a long shoot. I had a lot of issues here. So many issues that Discovery is gone. They left yesterday they ran out of time. My crew is gone and I finished the entire
episode all by myself. So hopefully you enjoyed it. Check out our other videos here. Check us out on Discovery. Hasta luego. Ate mais . Chao Chow.

  1. Here's a quandary for anyone who believes rockets don't work in space. Say you're in space and you're just floating. You're wearing a spacesuit and holding a basketball. You then decide to throw the basketball. Does the basketball move? If not, what's stopping it? If it does move, do you move the other way? If you do, then that's how rockets work in space. If you don't move, then why are you so different from the basketball in this physical interaction?

  2. What type of ignition did you use? Solid propellant is really difficult to ignite anyway. We used to use E-matches to ignite a small chunk of thermite, then bank on that lighting the propellant. The ignitor doesn't have its own oxidizer, so if it has to burn itself for a bit to ignite the propellant, it's going to struggle to do so without air. I have a bunch of solid propellant that is diffult to get burning with a lighter, but once it starts, it burns great

  3. This is from land air sea and space . they said they don't use solid rocket. to burn the rocket in space they use liquid oxygen because to ignite the rocket it's needed an oxygen like here on earth to make fire you need oxygen that's how i rocket work in space

  4. this is not a vacuum chamber!! do you really think we are that DUMB !? I can clearly see the wire going inside the box…. You ARE FAKE ! goodluck !

  5. My personal observation was ……the experiment failed when you could see the whole box. And then it worked when you COULDN'T see the whole box.
    Gotta say fail

  6. They don't really use rockets in space anyway, not for traveling to another planets. They use undisclosed anti-gravity propulsion which is based in aether physics, not conventional physics. Only scientists who are sworn to secrecy are taught aether physics by military. Read books "Secrets of Antigravity Propulsion" and "Uncovering the Missing Secrets of Magnetism". Check videos by "Mark Mccandlish" and "Paul Laviolette". As for proof of aether, the simplest proof of aether is in plain sight in the form of magnetic field. Magnets don't emit magnetic field, they manipulate aether around it forming an aether vortex scientific community calls magnetic field. You can also do simple experiment of spinning or moving strong magnet to create waves in aether and observe the effect of waves on cathode ray tube from 30+ft away. Also aether acts as a medium for electromagnetic waves and light waves. There is no such thing as empty space.

  7. This expiriment
    Rocket: 1-3x FAIL
    4x time Succes

    Rocket:1-3x FAIL
    Succes 4x

    LOL agree if you observed

  8. This video sounds like bullshit in the first 3 seconds when he conflates flat earth with rockets working in the vacuum of space. That is an old trick called "poisoning the well". Stick to science, bud

  9. As if the guy who make this video has an IQ over 12. He's a big lumphead. What kind of idiot thinks he has a vacuum when its a closed space filling with gasses from the rocket? DUH

  10. If you need to perform this test is because you are not analizing the phenomena from a microscopic pointo of view, atoms of gas (ie particles) expand in all directions, these particles are like balls launched against a wall, the expansion causes a change in the speed of these it doesn´t matter if there is gas or not, you just launch a ball against something that causes a reaction. No more discussion about these please.

  11. It makes sense, but another factor to consider is that all of these experiments reproduce vacuum but not gravity 0. So much so that you have to rest your devices on something fixed in the camera. Now we know that between centrifugal and centrifugal force generates a resultant that drives forward. These experiments all do not nullify the influence of gravity which may be the factor that generates at least minimal force with minimal reaction by burning oxygen itself and in a system that facilitates movement such as a soft spring or a propeller. In the case of space this does not occur.

  12. you need oxygen to burn…in vacuum you will only get smoke…what are you trying to do…

  13. In a vacuum traveling is very much like you running in your dreams . Not possible push & steer further around in space against void . What ever speed n direction you exit earth & enter space you go a go that speed n direction unless u hit some atmosphere / object . Don't fool no one pls

  14. The Rocket pressurizes the chamber , you cannot keep up the vacuum like space, not to mention the thermal dynamics on 450 degrees below zero, you can set up a Thrust gauge but you can't setup of mercury vacuum gauge, this guy is either being funded by a 501 3 C, or is Mickey Mouse… Rockets don't work in space

  15. I am not a rocket expert, but the sun already burning in a vacuum space, and I think this explains a lot (to Flat Earth believers). There are tremendous nuclear explosions happens in the sun per second.

  16. There is no room for gas dispersion in your experiment. Of course, it's going to create its own atmosphere for propulsion wtf. Come on now.

  17. This doesn’t seem very smart.. your rocket engine and ignitor requires some sort of oxygen atmosphere to be ignited. I am no rocket scientist but a proper engine for this project would be a design where the igniter is built into the engine in a protective case capsule where this engine will have its own h2o supply and it can be ignited in any environment. ??

  18. First of Your engine is all wrong.. it’s not even a engine is a rocket toy.. that requires the earth atmosphere to even start where a actually rocket has its own gasses and h2o to create the thrust needed.. so obviously if you take away the atmosphere and try to use your cave man rocket with fire igniters you’ll end up looking pretty dumb. Blow up a balloon and release it in a vacuum. The ballon has everything inside to propel it forward.. not pushing against anything, it thrust comes out of its small bell that works like a engine. That’s how a rocket would work. So how do you explain this cave man experiment?? 🤦🏾‍♂️ Yeah ..

  19. I can't believe this….. Because every action has an equal reaction (forced against 1st force). So if we throw a ball against a wall here wall acts like a anti reaction. If there's no wall the anti reaction is air. Then what is the anti reaction in space? I think there no air…No anti reaction…So no boundaries for rocket it can travel up a gravitational pull attracted them….The only base for travelling rockets in space is their ejected gases acts like a atmosphere or air……….

  20. Holy shit this comment section is giving me the fucking creeps. Like what, 30% of people actually think they figured something out and rockets don't burn in space. Yeah, they do, but a fucking pair of binocs and go to cape canaveral see for yourself, or I guess they figured out how to make magic. You don't need atmosphere for thrust, who the hell ever thought that? Every action has an equal an opposite reaction. That is why when they maneuver spacecraft, they call it reaction mass, you exchange mass "water vapor, whatever doesn't matter" for an equal and opposite reaction. Its pretty fucking simple. People are super gullible, whats sad is they think they have caught onto something, but in reality their just sheep, they can't accept reality and that tell s me that most of them don't have the best lives. Or they are just very effective trolls and dont truly believe such nonsense.

  21. From the FIRST MOMENTS OF BURN…not sustained. Shoot a gun in space and you will get thrust…kick back. Overeducated idiots!

  22. To simulate the vacuum of space, you need to create a vacuum that is removing the exhaust from the rocket as fast as it's being dispelled or you are creating a pressure that would not occur in the vacuum and void of an ever-expanding space.

  23. The top popped off i saw it so it wasnt a vacum after about 3 seconds into the experiment so its not valid!
    And the crew knew you & it didnt work & left u to waste your own time! with to many varibles not proven 100% a budget of mythbuster proportions in actual space could only ever create credible results but please keep wasting your time & not breeding please & use condoms if u find a girl somehow 😂😂 pmsl

  24. To be fair, SRB's are purportedly ignited here in Earth's atmosphere and jettisoned shortly after a spacecraft exits it.

  25. your experiment was good but your chamber was too small. The exhaust of the rocket propellant was creating an atmosphere in your vacuum chamber. This was why you saw the ignition far from the rocket. In actual space, unless there is a way to make an actual build up of oxygen behind the rocket there would be no thrust. Now since the rockets use liquid oxygen maybe that is the reason for the propulsion. But nice video…..

  26. You simply don't get it do you? And for the record, Newton's third law has absolutely nothing to do with rockets, nor does it validate how rockets allegedly work. It is simply a statement to describe that an an action has a resulting action. It can be one or countless resulting actions. Apply the law to an internal combustion engine. The opposite reaction is that the energy created, causes the shaft to rotate, causes heat, causes friction, causes a transmission to move, causes wheels to move, causes tires to move on the concrete, and eventually causes a car to move. With much of the energy created from the initial action, to be lost before that happens. Same thing with rockets. The energy is converted in many ways.

  27. This clown is a total idiot. The rocket produce more cfms then the vacuum pump. Thats why he wont show the vacuum gauge in the first place!

  28. For every action there's an equal and opposite reaction. There must be at least two bodies. A rocket pushes propellants out in which in turn creates a partial ground effect and high pressure behind the rocket and therefore pushes the rocket forward. In space were its basically Impossible to create a useful pressure differential due to its vast size and extremely low pressure, how does a rocket move?
    The propellants will just expand rapidly without any push back so why will it aid in propelling the rocket?
    Everything conventionally powered requires pressure differential move. That's why cars need friction to move, friction creates high pressure differential therefore the wheel pushes harder on the ground towards the direction of lower pressure and the car moves forward. That's why cars move slower in slippery icy roads because the pressure differential is much lower for the same amount of work.

  29. The experiment failed. The top of the chamber pops off at the end once the rocket turns on. This is proof that the chamber was not a true vacuum. In a vacuum, the pressure inside would be powerful enough to at least hold the sides together.

  30. Do the experiment in a giant vacuum chamber. Like the size of a barn. Have the rocket attached to cables. Ignite it using the techniques you showed. Perhaps the bigger the space the bigger the vacuum. Obviously a rocket is so small in real space. Would it still Behave the same? How fast and how far would it travel forward in real space.


  32. "I think that was enough proof for me". enough proof for me of a bias mindset. Rocket exhaust hits side of container and Newton's Law is confirmed. Cmon folks demand better. Thanks for the huge effort though.

  33. In a true, near zero vacuum, your box would have collapsed. There are just so many unrestricted variables in this "experiment" it is not even worth commenting on.

  34. Pateta burro, isso é desonestidade, usar um ambiente pequeno pra fazer essa farsa? S usasse uma grande sala com vácuo aí você veria que não existe propulsão sem nada para reagir., no vácuo.
    E a Terra continua sendo plana, Flat Earth forever.

  35. 1. You can’t create a zero torr vacuum of space
    2. You should have tested in normal sea level and the under your increased vacuum and compared the results. My bet is decreased thrust with increased vacuum thus disproving Newton’s law.
    3. You should have expected to see constant thrust if your theory was correct.

  36. Some comments are so stupid. People thinking it was not a vacuum before the engine fired, because afterwards he could lift the lid off. Duh, that was 'after' he opened the valve to let the champer get back to atmospheric pressure, you genius!

  37. Basketball analogies just flat wrong. If you want to use the basketball analogy do it like this. You're holding a basketball you poke a hole in it the air begins rushing out, you and the ball stay stationary and the ball goes flat. People explain that rockets work by pushing against themselves. I question that analogy. I'm no doctor or expert but in my observation the rocket works because it's creating a highly pressurized area and pushing against the 14 lb of atmosphere it is operating in. Can someone please tell me how a rocket actually makes an object move here in our atmosphere and in space?
    It seems to me odd that it would function the same way in a vacuum and in a pressurized system.
    That question leads me to my next question. What is the accepted theory that explains why our atmosphere does not get sucked out into the vacuum or simply float away? For clarity example, you make a lucite box with a divider in the middle in one half of the box you create a vacuum equal to the vacuum in space, in the other half normal sea level air pressure. you remove the divider what happens? it seems to me the pressurized side would move to the vacuum side and dissipate the overall pressure to7 lbs. I'm not being an ass whole, I really do want to understand, what happens in that lucite box and the possible explanation is fascinating. Whoever answers, thank you in advance.

  38. You are told space has a vacuum to to dissuade the common man from buildi ng a rocketship to leave. All these barriors only gov approved entities can go in space….. Space is fiction in the first place!!!

  39. Just the fact that in the last run it got "stuck" and no further runs were made, shows that you didn't want or someone else doesn't want your findings to be released.

  40. That tiny vacuum box is why you got the result you did, put the same rocket in a complete vacuum area the size of a gymnasium and I bet you'll see a different result since the space will be to big for the rocket to create an atmosphere in.

  41. Hmm, let's think of Bob and Alice are hanging in the space next to each other. Bob weighs 200 kg (~400 pounds), and Alice is 50 kg (~100 pounds). Alice tries to push Bob away as strongly as she can. How much will Bob and Alice move away from each other as a ratio?

  42. The vacuum chamber is too small and the chamber itself can’t get ANYWHERE NEAR the actual vacuum levels in space. Not even close

  43. What everyone's no realizing is that in this "vacuum", it's air we care about. We can't have any oxygen. We can have methane and other gases, but the oxygen is what we can't have any of

  44. Look vacuums can operate theoretically in space but this experiment doesn't prove dick since they don't maintain the vacuum (the chamber fills up with gas from the ignition of the rocket) DUH DUH DUH DUH DUH fucking retards

  45. the air pressure determines the shape of the bell of a rocket's nozzle — as pressure reduces, they need a larger nozzle for optimal output

  46. Soda can opened in a confined vacuum renders the vacuum gone! Open it in an infinite vacuum and yes the contents will be released but there cannot be any thrust because the soda has nothing to push against!!!

  47. I’m sorry but the expelling gas ruins the experience of a vacuum out in outer space as fast as you could consume propellant you would expand out as well into 0 atmosphere

  48. Could you please demonstrate gas pressure being maintained in a vacuum chamber? Perhaps you can bend some space in there (Einsteinian gravity ) and show how gravity will hold down gas pressure within the vacuum without a solid barrier. You know, like how we're told we live on a space rock coated with water and gases in an infinite vacuum. Common sense and every scientific experiment in history reveals gas would fill the available volume instantly. So would be a real slice to such a phenomenon demonstrated in actuality apart from mere conjecture from not so honest government space agencies.

    Also could you please demonstrate how mere gases (like our atmosphere ) shield water from boiling in a vacuum? You know like how the oceans don't boil in an infinite space vacuum.
    Thanks a million! 🙂

  49. If your rocket is in the vacuum of space, your rocket wont work like the first attempt. But if you reduced the vacuum pressure it will work like the last attempt. LOL

  50. The vacuum of space is trillions of times bigger than that zero attempt. The 'thrust' is coming off the far wall. Go 30,000x times larger. Newtons Law still applies news papers across the nose or not.

  51. …no – an infinite vacuum would constantly be able to absorb what was pushed out of a rocket at a rate equal to the force created out of the back of the rocket immediately – a rocket in ‘space’ would go NOWHERE !!

    …prove me wrong.


  52. If you want to make an experiment on how thrust works in a vacuum, why not attach a really big bouncy ball filled with air to a common but functional household vacuum and see it it can launch. This gives more than enough advantage to the ball as it has the sides of the hose to push against and a household vacuum is nowhere near 2 hydrogen atoms per cubic meter emptiness of space.

  53. For starters ROCKETS ARE USED JUST TO LAUNCH(Ignition which is produce with air)ONCE IN SPACE THERE IS ANOTHER MECHANISM THAT IMPULSES THEM(Newton’s third law)*. Which gives this experiment a very obvious result (no oxygen not combustion). *in order to prove Newton’s third law in vacuum would be better to put a slingshot like in a vacuum chamber or some container expulsing a gas throughout little orifice note: in space there’s nothing sucking air. So not pressure you would be floating.

  54. Cool video, good work 🙂 Consider building liquid methane (liquid natural gas) + cryogenic O2 rocket with more power & longer runtime 🙂

  55. So I admit I don't know squat about physics and equations… but it seems to me if you had an infinitely powered giant vacuum hose under a rocket launch and then you switched on the vacuum at the same time as the firing the rocket… would the rocket move? Or would the vacuum just suck up all the propulsion.. I suppose to be fair you would also need to have a giant hose above the rocket at the same time… hmmmmmm…
    I'm going back to watch UFC videos now

  56. it only start producing thrust after the chamber if filled with smoke, not before, pay attention to the video. Is there thurst when there is no gas inside the chamber? We still don't know.
