Accidentally Opening the Airlock in Space Will You Get Suck Out?

In this video, we test what happens if the airlock of a space station is accidentally opened, causing all the air to escape in an instant. We also simulate another extreme scenario: a saturation diving chamber accident where a pressurized chamber is mistakenly opened. Watch as we explore the effects of sudden pressure changes on the environment and the potential consequences for anyone caught in these dangerous situations.

[@leopiipponen7693]

The ISS space station has normal atmospheric pressure and is "made" of oxygen and nitrogen. The air humidity is approximately the same as on the ground, which means there is moisture. If the air was completely dry, it would be a big problem :)

It's not ISS space station. The "SS" is short for space station. So you call it the ISS or International Space Station. You don't say "ATM machine" or "LED light" do you? Because if you do, then you're talking wrong, being redundant and wasting oxygen, while upsetting pedants everywhere. LED is light emitting diode, so "light emitting diode light" is redundant. ATM is "auto teller machine" so "auto teller machine machine" is redundant. That's just my 2 cents.

What is generally forgotten is that the pressure differential between one atmosphere (space vehicles use 1 bar only) and hard vacuum is only one atmosphere / 14psi. It's not like the pressure differential on a deep sea submersible

[@anteshell]

It's not really forgotten. It's just very unintuitive concept to understand because we don't have readily available vacuums to see and test in our everyday life. And many examples that we have appears to prove the opposite at the face value. For example, if you shake a can of soda made from thin sheet of aluminum, it will have multiple atmospheres of pressure differential but works just fine. However, you never see vacuum chambers made from thin aluminum sheet that could withstand the pressure. If you suck a vacuum to a soda can, it will buckle way before reaching one atmosphere of pressure differential. Understanding why this happens requires much more knowledge about physics than what you can simply infer from looking at buckling or bulging soda cans, and most people don't have it. It's very unintuitive and against common sense, which makes it hard to understand for laypeople.

[@zmgehlke]

@@anteshell -- Soda cans are more like 1.2atm; that's why they don't bubble even when shaken on a submarine which typically operates at 2atm.

[@anteshell]

@@zmgehlke The exact numbers are irrelevant to anything I said, because I'm not talking about the math. I'm talking about the reasons why people don't understand this phenomenon. And still, soda cans absolutely do bulge and I've had a couple even exploding to my hands due to too much pressure inside, if you mean that by "bubbling". But that is also caused by the liquid bubbling and releasing co2, so that happens too if you used the word "bubble" correctly.

[@zmgehlke]

@@anteshell -- The difference matters, because a vacuum is 5x the pressure difference between a soda can and outside air. You're trying to make it mysterious, when really, it's just a higher pressure differential.

[@Aisamiez]

[@Nefville]

So the good news is if you're ever on a space station and the door is opened, you will probably not be blown out. You will however suffocate rather quickly, the air in your lungs will be forced out at 14.5 psi, your blood will begin to boil and after quite some time (poor thermal transfer), you'll freeze. The bad news is you won't see shit, not because of the water vapor but because the fluid in your eyes will also boil. How will it escape? GRIM.

[@youkofoxy]

Space station are usually below one bar, as they have a rich in oxygen environment. I just do not remember the exact number (0.8? 0.4?) but is pretty much high altitude city pressure.

I can't help but wonder why you needed help getting the end off your test chamber 🤷🏻‍♂️ You're obviously plenty strong enough, and you have all the right tools for the job. 🧐 Your little 150t press definitely could've held that chamber down without any problem 😉 I love your channel, keep the videos coming 🥰

[@leybraith3561]

... I imagine that most astronauts (in the quest for a balanced world) think its now appropriate you produce a video of an experiment / diorama duplicating your test lab and what happens to onlookers if the polycarbonate barrier fails during one of your more energetic explosions...

[@solanumtinkr8280]

Well, the common misconception is being sucked into space, when it is being blown into space by the air behind you. It sounds like a minor difference until you realize one would spaghettifiy through a small hole as you are "sucked out". The other just ends up with your thumb blocking the hole as the pressure difference of 1 atmosphere is not actually that great, or vacuum cleaners would be WMDs.... It's the pressure difference that does the work, and pushes... So if you are in a sealed airlock, which door you were up against would make all the difference, the inner or out door. The outer door would have the mass of air beind you pushing you out. The inner door the air is just flowing away from you, anything behind you will 'push'

[@napalmholocaust9093]

Doesn't take much pressure change to make clouds. A science project a long time ago demonstrated it by punching a sheet of rubber down over a large mouthed (4L/1G) glass jar.

[@TheOriginalFaxon]

rapidly decompressing any chamber is an endothermic process. I would think that suddenly decompressing any gas would result in some amount of vapor production as some amount of the gas turns to liquid, since the energy distribution won't be uniform and some molecules will get cooled more than others. I've never seen a gas cannon of any kind that didn't produce some vapors when fired, whether it was powered using air, nitrogen, or carbon dioxide (those are the only gasses I've seen used this way, the other setups all burned whatever gas was used for more propulsion)

[@biohazard20161]

What you need is a vacuum chamber big enough to put your pressurized vessel in, with a metal frame, thick polycarbonate walls, a wireless remote to open the "hatch". Pressurize the "space station" close all valves on it, disconnect all hoses, and place it in the vacuum chamber. And then conduct the experiment.

[@KainzMusic]

0:17 This needs to be on a T shirt!

[@puremaledark8305]

It would be really interesting to see 1bar into a larger vaccum. I cant imagine the station is pressurized more than 1 bar and space is a total vacuum. That one bar might do way more damage than you think into a vacuum.

[@dlby3]

This wasn't a disappointing video at all. I watch your videos for the commentary and Hanna's screams. She's such a scardey cat. Holy Sheet! haha

[@camojoe83]

A big enough door opening fast enough will "blow" you out into the void rather than the void "sucking" you out. Also, there's no vacuum in space. It's just 0 pressure. There's nothing there to "suck" anything.

[@BlackAlbinoDragon90]

[@hectoris919]

What if you put a ballistic gel head in the pressure chamber and pressurized it with water, then opened the valve? Do you think it would be forced through that small opening? Or would the water just bore a hole through the head?

[@wdavem]

😂 Well, hey - you did get the right kind of mist in the end. I'm pretty sure the last thing you'd is just white air. Also I really like the idea of "what will go through the valve?".

[@DinJaevel]

And on the subject of moisture onboard space stations. They had an electrical fire onboard Mir and when they removed the panels, they found a huge blob of organic puss that had grown there. Just because moisture, bacteria, filth and everything such takes on another life when in space. I have not seen pictures of it, but heard it described, and based on that I feel no need to.

[@robertcorbin464]

It would be neat to see this recreated with a internal mounted thermocouple to see what sort of temperature is reached due to high P and constant V. Havent seen many PVT diagrams for pressures needed to cook chicken, but im not sure if thats still considered raw at the other end.

[@ihaveanunorigionalname]

u dont need a vacuum pump just put the pressure vessel you used to shoot jets of water and run it backwards you can mae a super vacuum chamber just by making a large cylinder and remove the piston to make a fast vacuum. imagine making a 2 foot long chamber that a rod is removed from at high speed to make instant vacuum. atoms cant be pumped out well because they need to migrate to the pump but increasing the chamber volume will seperate the atoms immeduiately to the vaccumnes that would take a hour to pump down to with molecular pumps.

[@eagle94haslanded]

I think the point your missing is the zero gravity part.... the theory is with no gravity its easy to get sucked right out. But i dont believe its realistic. Might move you a decent bit but your mass is much greater than the mass of the air leaving.

[@TheGeezzer]

In the _Byford Dolphin_ accident several men experienced an explosive decompression whilst on an underwater drill rig saturation chamber out at sea. All of the men died, instantly. One man was sucked through a tiny 18in aperture, his entire body was shredded into mincemeat, his innards were sprayed all over the compartment walls. I think it was 9 ATM down to 1 ATM in one millisecond.

[@HarmanRobotics]

If I remember correctly, it was the gap formed by one of the doors being blocked from fully closing. So more like a slot a couple inches wide. Regardless, it was over so quickly those guys don't even know they are dead. I highly recommend NOT searching for images of the incident.

@@HarmanRobotics Yes I believe you're right, it was the gap in the door he got sucked through! I saw images of one of the guys who exploded, just a bit of torso with a fragment of thigh and half an arm attached. Terrible but thankfully killed in a micro-second!

[@Physhi]

Airlock opened in space is not sucked but blown, a simple misconception.

[@HarmanRobotics]

True, there is no such thing as "suction, and it is good to understand that; but that word does serve well to describe the effects of differential pressure.

[@oglordbrandon]

It is just a pressure differential. There is no difference between suck and blow from a physics perspective only a mental one concerning the source of the power. If you added another module outside the airlock of infinite size then pumped the air out of that, then opened the door between the two the result would be functionaly the same. The bouncing air molecules don't know where the motor is. So things are blown into your vacuum cleaner as much as they are sucked into it.
