It turns out, you didn't get extruded into that little bottle. Phew. That's relief.
Fraser Cain omg 200000 subs that’s pretty awesome
I asked that question under a Fraser video, guess you won't need to answer that now :)
one of these days we'll get cody into a small container, one of these days...

Thanks for the demo!
Great suggestion!
:D
I love both of your channels and the content they produce. In a week or two i should have a video coming out testing different model rocket thrust if you guys want to check it out.

Did we get some duct tape in KSP yet?
PHIL SWIFT HERE WITH FLEX TAPE...TO SHOW THE POWER OF FLEX TAPE I DRILLED A HOLE IN THIS SPACE STATION
Lol
Nice
THAT'S A LOT OF DAMAGE!
NOW I'LL FIX IT USING ONLY THE POWER OF FLEX TAPE!
OR TRY NEW FLEX SEAL TO SEAL CAULK AND BOND FOR QUICK AND EASY DAMAGE REPAIR
This is the closest you'll get to a Cody's Lab video sucking
Just making sure this was a joke like I assumed?
But is the vac pump sucking, or blowing? Who can know for sure?
It's transferring....
@@jerotoro2021 4:58 if it was blowing his skin wouldn't be doing that
Actually... there was that one time him and Grant Thompson had a mercury sucking contest... :P
Hi Cody, thought I'd put up a quantitative explanation for the minority of commenters who aren't convinced by your qualitative one.
People are saying that "thats nowhere near the vacuum of space". Well, according to absolute pressures from wikipedia:
P1(low earth orbit) = 10 nano-Pascals (at lowest)
P2(water boils at room temperature) = 2.6 kilo-Pascals
P3(atmosphere at sea level) = 101.3 kilo-Pascals
So yes, pressure of vacuum in low earth orbit (P1) is 260 Billion times lower than what Cody had in the vacuum tube (P2).
BUT! The force on his finger doesnt care about the ratio P(vac) / P(atm), but about the PRESSURE DIFFERENCE P(atm) - P(vac)
In codys experiment, this pressure difference = P3 - P2 = 101.3 kPa - 2.6 kPa = 98.7 kPa
On the ISS, pressure difference = P3 - P1 = 101.3 kPa - 10 nPa = 101.3 kPa
Therefore the force experienced by Cody's finger and that experienced on the ISS are only 2.5% different!!! ( from (98.7 - 101.3)/101.3 )
Yaay, math!
Good on you for doing the math for the rest of us mathematically illiterate idiots :)
lol no problem :)
don't label yourself as math illiterate though, it all depends on finding your own learning method. I firmly believe anyone can do it if they figure out how they learn to understand it logically for themselves, instead of having to remember a load of arbitrary facts and rules.
btw I just noticed the formatting in it is a mess, imma fix that now
You math-wizard :P
Pretty sure I literally am, never paid attention in school and subsequently can only do math in my own head. Can't write down even the simplest of formulas, don't know what calculus is and nor do I really know what a square root is. Essentially I only have the mathematical skills we humans are innately born with, which makes me mathematically illiterate :P
At least my English is good, as good of a consolation as any I think. It is my second language after all :D Never learned that in school either, its all from shit-talking on RUclips and Reddit from the age of 12 :D
Edit -- seems the ISS does use sea level pressure --- before ISS pressures were much lower, and even still in space suits, they're 4.7 psi. Due to the O2 generation systems, they use near earth pressure in the ISS. Higher pressures aren't required, but are utilized so that equipment developed for environmental controls don't need to use vacuum chambers for dev, nor does it complicate the science missions on board.
That vacuum pump is capable of reaching 75 microns (.01kPa), which is much lower than 2.6kPa.
The solution is Flex Tape.
Flex seal*
Overactive Imagination flex tape would probably be more effective in they case
Just don't bring Phil Swift on board...he might saw the space station in half.
That's a lot of damage!
It would just get sucked out before it set.
I would caution against using fingers as your primary emergency sealant material, as rubber plugs are usually far cheaper, and less subject to boredom.
That and as safe as this is, I'd not want metal splinters/cuts. XD
Another problem is the the finger will need food and water. 😀
@@airkid4457 not necessarily...
@@oliverturner1649 oh........ Ok then..........
What happens to rubber when exposed to the near absolute freezing temperature of space? The same thing that happens to fingers...
It's really not environmentally friendly to run a vaccuum pump and to suck out all the air like that.
One day there won't be any air left and you will be to blame.
I really hope this is a joke. If not then congrats your stupidity would top that of all flat earthers

Professor Farnsworth: Dear Lord! That's over 150 atmospheres of pressure!
Fry: How many atmospheres can the ship withstand?
Professor Farnsworth: Well, it's a space ship, so I'd say anywhere between zero and one.

"Good news everyone! I found even more mercury!"
Love it
I think its the idea dome or thinking dome. I cant remember. Ive only seen the episode 5 times.
One of those things that people might be inclined to think that is super dangerous, but the calculations for it are actually very simple and show how it's not really dangerous at all. Assuming a hole of 1mm radius and with a differential pressure of 1 atmosphere: 1 atm * (1mm)^2 * pi = 0.32 newtons, or roughly 33 grams of weight at earth's gravity. Pretty small indeed
Showing of your simple math skills by using smart words?
@@SubsWithoutavideo-zp3kh whatever makes you feel better man
Alexandre Truppel but for the tube one it would be around half a cm radius which makes the force around 25 times stronger?

And put on some flex tape

how would you propose stopping a small hole within 2 seconds of finding it?
that's a lot of damage.
Stick a chewing gum on it....
@@speedy8260 like any professionalt they are paid not for the solution but for knowing what the solution is
I regularly have to deal with large industrial vacuum pumps at work. If there is an issue, the way we usually make sure the pump is good is to put your hand over the 2 inch inlet at the pump. Then work your way down through the hoses. Always make sure the pump is good first. We can use gauges, but they are not always available or practical. Anyway, the longest I held my palm to one of these pumps was maybe 3 or 4 minutes. The worst damage was a 2 inch hickey on my palm that itched like crazy for the rest of the day. That said, I wasnt worried about solar radiation and extreme temperature swings either. Also, duct tape. It really does hold the world together.
"TO DEMONSTRATE THE THE POWER OF FLEX SEAL, I DRILLED A HOLE IN THE SPACE STATION"
I literally love you man! You are the spirit of the fun of science, just like Feynman was!
but what if there are aliens outside your spaceship? could you do it then?
tomatoanus what the hell?
is this fallout 5 plot leak
Absolutely, you just need to fire your keychain laser pointer through the hole a couple of times first, to get rid of those pesky buggers...
in that case you really should do it because otherwise the aliens will extrude through the hole into your ship
Sure. Call Immigration and Customs Enforcement (ICE) and have the aliens removed...
Whatever space debris caused the hole was far more dangerous
It was your content... Because it is so dense...

The initial boiling is not water vapour but usually pulling dissolved gases out of the water. It then settles down and then starts truly boiling when the water vapour pressure is finally reached.
My father was actually the project manager for the development of the meteorite damage repair kit. It essentially is a metal plate with a rubber pad on it. Very similar concept to putting you finger on the punctured hole.
Would be so great to have a collab between Scott Manley and Cody.
_For clarity, I personally wouldn't advise you to plug a half-inch hole in the space station with duct tape._
I would advise plugging a half inch home in a space craft with duct tape or anything you can find.
The less the leak, the longer to fix.
Sometimes you just don't have many options.
A test-tube cork?
you could plug it with water I think
Damian Reloaded Not sure you know this but water is kinda important to have _inside_ the space station out in space.
All the things this guy goes through to make his videos interesting for us! So great keep up the good work
Awesome! I just watched Scott manly's video earlier today and was thinking about how interesting it would be to actually see someone trying it with a vacuum pump.
Thanks for being awesome Cody! I love your experiments

i heard news of the leak on the ISS but i wasnt expecting a video from you. So thanks!
Thanks for another great video, as always, Codydon
Once again, the Cody delivers. Awesome.
Reminds me of a story by Hienlien, "Gentlemen, be Seated", in which a man must seal a leak in a lunar dwelling with his behind. Painful. You would think astronauts, real and fictional, would stock patching gear and materials to avoid the need to improvise.
I remember that story; a small crew of lunar tunnel workers were trapped in a tunnel section with a fifteen-centimeter hole in the steel shell. They took turns sitting on the hole. the major danger was losing body heat into the cold steel shell. The only injury was a strawberry-sized welt on the buttock.
Unlike the demise of the alien in Alien Resurrection. :)
Well that's because that alien was made out if toothpaste.
@@brianreddeman951 ha ha
I actually liked that movie. But good gravy, as a science nerd, that scene was cringy. Not that any of the alien movies are hard sci fi by any stretch.
@@patrickmccurry1563 Exactly. Turn off logic and enjoy the horror or action (depending on the film)
Awesome movie, some great actors and director, plot gets a bit corny though.
Thanks Cody! I knew this experiment was right up your alley.
Thanks Cody, great informative video. Love this channel.
If you went to something like a 2 inch diameter, could it rip off the skin on the palm of your hand? At what point could you expect serious injury from trying to stop a leak with a body part?
Skin is really strong, you would probably break bones and cause other damage before you rip the skin
That's a good question actually, I'd also like to know
Would be an interesting follow up experiment at what point it can suck out a human.
I've tried plugging the inlet of larger vacuum pumps with 40mm inlets using my palm, and my hand is still intact.
The force would be larger, but also the surface it's acting on. So probably there wouldn't be a big difference.

Holy crap Scott Manly just thanked you for this video! Too cool dude!
Yay Cody posted a video on my birthday!
Yasss! Scott Manley and Cody Reeder, unite! Lol
Wonder what a colab would look like, home made rockets?
*yes
They'd make a kno3 rocket that would reach space of course! No one has done that yet!
The Kapton tape they used on the ISS is really cool because it has a huge temperature range.
Maybe you can make a video showcasing different stress testing of it in a Space environment.
Ok, this makes sense. We always think of it as the vacuum “sucking” the air out, but it’s actually the air “pushing” into the empty space, so the maximum pressure it can exert is based on the interior pressure, not the exterior vacuum. Interesting.
Thanks you just made this clear to me in a way I've never understood before
@@faithful451 It really is the little things that make a difference. In space you want to build a vessel that CONTAINS pressure, not resist it :)
Great demonstration as always, couldnt stand some of those comments! :)
Thanks - instant like!
Please what? I just couldnt understant how someone could believe in such nonsense - not more not less
I wonder if being hit by a 2mm micrometeor could kill or cause serious bodily injury. Seems like if it could punch a hole through the space station, it could very well punch a hole in a person.
It's pretty much a bullet with how fast it's moving relative to the space station
+Alex Siemers Yeah, and let's say it's about the size of a bb. A bb that weighs .25g travelling at 20k fps (3.8 miles/s) has a 3400 foot pounds of impact energy, which is almost 9 times the energy of a typical .357.
I doubt you'd feel it. It might feel like a touch. In a minute or so you'd start feeling it though, depending on which part of you it went straight through.
I doubt it would pass through, looking at some of nasa's nitrogen gun videos, if it a much as grazes you, the shockwave would kill you outright :P not much feeling that hehe
I think it would probably fragment very soon after entering flesh. That's a very high velocity and the stress on the micrometeorite would be huge. I'd think you'd get a shallow but very ugly wound.
To show you the power of *FLEX TAPE* i sawed this space station in half!
lost my shit at this comment.
Extremely interesting vacuum video. Also 6:23 with the magnets and the coin. Capitol WOW. Cool.
Cody, you've really a cool guy. Thanks.
My first thought on the idea of orbital debris punching a hole in the space station is that we'd expect to see two holes: one going in and one going out. But I guess since there's no hole, all of the material from whatever caused the debris came to rest in the space station. Maybe it didn't have enough momentum to punch through the other side and just bounced around a bit before stopping, or got stuck into something soft and squishy. Maybe it shattered when that happened. Or maybe it vaporized or disintegrated when it carved through the air inside the space station. I wonder which of those is most likely.
If it's a tiny piece of debris(like _really_ tiny) with a relative velocity of km/s then it would probably vaporize, I'd bet the size of the hole was many many times that of the object itself.
In a hypervelocity impact, the projectile is usually vaporized, I believe.
What's the difference between a hypervelocity impact and a lopervelocity impact?
If air is leaking shouldn't the hole be in both sides?
great now I want to see a surface with a hole on only one side
"to show you the power of flex tape, I sawed this spacestation in half"
I like that eddy current vice thing at the end. Its like you did everything you could to increse the strength of the eddy current.
I'm so glad, that you did this.
Cody you have several vaccum Chambers and youre a genius , time to recreate electro booms Tesla in vaccum , seeing the electron flow and maybe the effects of a magnet would be very cool and educating :)
Greetings from Germany
Yes
Cody continue precious metal refining and codys mine!
He said the reason he stopped doing Cody’s mine is because RUclips started demonetising them because he used (perfectly legal) explosives that “don’t comply with RUclips’s guidelines”
Wooh Cody's Lab!
I really appreaciate your videos :D
This is pretty trivial stuff, but had to be done. Thanks, Cody.
I wish Scott Manley would ask me to make a random video. Fly safe!
Hey, awesome demo! Quick question out of curiosity. If you were to put soapy water into a bottle like this and created a vacuum, would it produce bubbles?
Back long ago my dad subscribed to Analog (monthly scifi mag). And in one of the issues there was a story about a space station where there was a small group of folks who were working towards a common goal (don't remember what) but the main thrust of the story was that one individual among the workers that was annoying af. Everybody hated him, and everybody shunned him. They actually were united in their dislike for this awkward annoying guy. But then there was a meteor strike that ripped a jagged hole in the habitat and the annoying guy used his body to seal the hole. But as it tore through metal, the jagged hole cut into the annoying guy as his body sealed the hole, and he bled out as the vacuum he was sealing against the habitat pulled the blood from his body through the deep cuts it caused. In the end, they learned that his whole purpose was to be the focus of their annoyance so that everybody else would work together efficiently while he soaked up all social ills normally found within groups of people. It pretty much captured the human experience well. I miss old school Analog. Now cut open your finger and put it in a vacuum, otherwise you disgrace his hypothetical sacrifice. Also, love ya vidjeos. Do it.
Always informative, thanks!
So what you are saying is that alien resurrection lied to me? *insert lack of seriousness here*
When are you going to open up your Tin Can Cody?
Excellent idea. An idea can change the world
This was the first codyslab video I watched. I've seen every video since this video. It's been nearly 4 years since I sat at my grandmother's computer and watched this video. It's been nearly 4 years.
Whatever you've been up to, try some gloves. You have the hands of a 60 year old bricklayer.
I’m stupid so I just need a question answering even if it seems pretty obvious.
When water boils in a vacuum, does it become hot, or just stay the same temperature?
It gets colder.
@@theCodyReeder Wild!
Great vid, 2 of my fave youtubers!
So glad to see this! Fed up of the mad statements of a whole person bones and all would get sucked through a 2mm hole in space!
I am not surprised that Scott asked that at all.
I am pretty sure he knew exactly what would happen and that there was no danger for Cody..
Yes. The math puts it around .2lbs or 1 newton of force.
What?
That hole looks bigger than 2mm!
+Gresi Lamaj Yeah, I'd guess somewhere around 3.5 mm. But it's just a proof of concept here, I don't think the outcome would be different with a smaller hole.
@@Mp57navy Yeah 3.5mm seems about right!
Loved the eddie current brake demo at the end
Yeah I've explained to people repeatedly over the years that since atmospheric pressure is only about 14.5 PSI, the maximum "negative" pressure from a vacuum is about 14.5. Not too tough to deal with.
Alien 4 was a lie!
Too many people are getting their education from movies/youtube/tv shows instead of from common sense.
Millennials.
In a world of 'instant information', it's almost as if nobody actually critically thinks about the problem at hand, how it works, how it would react, nope... look it up on youtube and never think about it again.
There is no such thing as common sense. If it existed, sense would be common.
Common sense tells me, without an exit hole.. Whatever made the hole is still inside the ISS.. DUN DUN DUNNNNNN! Aliens..
I guess maybe, but are you denying what's going on in the video?
Thanks for sharing Cody :)
This stuff is effing amazing, keep it up! 😁👍

CrepticMoon yep. RUclips is officially not an alcoholic.
What about the temperature outside ?...would that make a difference on your skin ?
Great video...;-p
Unless it was in direct sunlight, the lack of external atmosphere means that heat transfer would be negligible.
from what i understand,temperature in space isnt "low" since there is no cold gas/air to do convection... he would only loose heat by radiating it and that takes long time....
Yup. It's rather telling that the temperature control part of a space suit is not typically _warming_ you. It's _cooling_ you...

Awesome work cody!
You’re an awesome dude, dude!
I think the concept of "Vacuum as a Force" has warped the minds of not only movie makers, but also most of my friends (i.e. most of mankind). I keep telling them that it is pressure from "the other side!", and again they go and make their own interpretation... My interpretation before the video, was akin to a water balloon (filled with ballistic gel, or spam, if you like), and pressure applied from outside. Also, one bar of pressure, 10m water column would not, and could not rupture your skin, as it is pushed, not pulled. Keep posting videos.Its a shame you get demonetized so much. Sometimes I wonder if Google/youtube belong in the bible belt.
Oh, you're discovering how ignorant >99% of humans on earth are?
Well, yeah... knew this from birth. What can you do?
Can give them a hard time and replace them more aggressively. They do have a tendency to murder "accidentally" people smarter than them.
Skynet or Westworld style?
It's the absence of pressure.
If the earth is supposed to be round, then how come duct tape is flat hmmmm explain that.
Well yeah but the Earth is out in the vacuum of space - and you could see as soon as the pump was turned on the tape started bulging too...!
Somehow this makes sense to me...
because if you take a pear and zoom out far enough it becomes a perfect sphere if a cosmic god rubbed his finger over earth, it would be even smoother than a cue ball. And if you zoom in it's flat - Neil armstrong degrasse tyson
I knew there would one FE comment. Even if it's a Poe comment lol
Well you see, duck tape comes on round rolls.
that clip at the end was so freaking cool!!!
i like this video a lot. Way too many people think so highly of the dangers of vacuum. Everyone thinks that when you take one step out of the spaceship unprotected, you will instantly fall over and die, frozen. That's not exactly how it is.
That time an elephant got extruded into a runaway diesel engine..?
Thank god... not that it'll shut the idiots up. And of course, they didn't JUST use duct tape, they used epoxy too, which I imagine makes an even stronger patch over the hole and reduces the gas diffusion through the duct tape even further.
They probably used a metallic tape like proper HVAC duct tape (the grey fiber reinforced stuff is crap)
@@RobertSzasz They used Kapton tape.

In space metal isn't very good at blocking a whole lot of radiation anyway it's actually one of the major problems we have to overcome before we can send people to mars
Yup, the space station doesn't really protect them from radiation very well. At least not the hull. They store their equipment and supplies on the walls of course, that does the largest amount of actual shielding.
But the astronauts that spend 6 months on the space station receive the same amount of radiation most survivors of the nagasaki and hiroshima bombings received. It'll increase their risk of some types of cancer slightly.
They receive doses which are well over the exposure limits in other work places. In canada the limit over 5 years is 100mSv total(and 50mSv per year).
Depending on where you are on the iss, you might receive something like 100mSv of radiation in those 6 months of stay.
So i am not quite sure why that is legal, but thats how it is. Theres not really any shielding. Goverments are kinda ignoring it, because they know they can't bring any heavy shielding up there.
Cody exposes himself to the vacuum of outer space - wow!
I love the vids man keep up the great work hope you get to go to space man God bless you
But I heard the earth is flat and no one has ever been in space.

While not as much of a risk in outer space, delta-p is a big risk to commercial divers because the pressure differences can be significantly higher than 1 atmosphere. It just reminds me of the "crab gets sucked into an underwater pipeline" video
Which then reminds me that this has happened to actual people the same way. The only solace being the delta-p is so great that you are pretty much instantly killed.
That vise setup is pretty awesome... if you could recycle the coins, you'd have a pretty epic desk toy.
