Stop me if Im extrapolating this data too far, but if I vacuum chamber myself, does it count as a shower?
leaving a comment here in case this thread goes where I think it will
Not only that, I think you will get steam cleaned on the inside as well.
Well the walls of the vacuum chamber definitely gets „showered“!
As you are exposed to a vacuum , your eyes begin to bulge and turn red as the fluid within them vaporizes😍. Frost quickly forms around your nostrils as moisture escapes and freezes😤. Blood vessels in your face burst, causing blood to ooze from your eyes, ears, and nose🥰. Your mouth foams and froths as saliva vaporizes🤤, and any attempt to hold your breath results in ruptured eardrums and severe internal damage🫨. Your face swells grotesquely, giving you a distorted, horrifying appearance🫠.
@@pacresfrancis1565yay!
If someone's clothes smell like rocket propellant and campfire, I'd be wondering:
1. What kind of wild party you went to
2. Why wasn't I invited
These are great questions the TSA agents will ask next time you're at the airport!
Sounds a bit like war
A few years back someone in my city set their dorm room on fire trying to make Rocket Candy
Maybe NASAs campfire taste infusion division (CTID) and rocket fuel research facility are one and the same?
@@korumann did said rocket candy have a suspiciously complicated laboratory involved?
It really does work! I tried smelling the video and I couldn't hear any smell of smoke. Joe isn't lying
I don't know. I smelled a bit of cookie dough (totally unrelated that I was having cookie dough ice cream at the time).
@@MrNorker77 actually that's because the pot is from a dough mixing machine
Would you post a timestamp, please...? I want to smell it, too. 😛 😀
I have synesthesia, can confirm, I would've heard it loud and clear. Smoke is kind of a whiny grumbling, a residual from the wood fairies pissed that they were combusted.
Joe Barnard bakes cookies in a vacuum and fills them with graphite
No, graphite is an icing!
Didn't Red/Blue Nile bake cookies in a vacuum stove as well?
The perfect cookie doubles as a heat shield tile
Nothing better than vacuum cookies and carbonated milk....
You didn’t see graphite on the ground
This just makes me think they should add a "washing line" to the outside of the ISS
They want that water to recycle it, so today's pee is tomorrow morning's coffee. However all the old laundry does get thoroughly cleaned when it is replaced, as it goes into a Progress capsule, and then has a very high temperature wash cycle over the South Pacific Ocean, when the Progress deorbits and attempts to land on a precisely determined spot, but burns up before then, and all the clothing burns up from orbital entry.
Comes with free micrometeorite holes!
Are you sure they don’t have one of those?
@@vosechu I imagine they might just have a chamber that can be accessed through a hatch, for just this purpose. But I think they also have some over-engineered washing machine that engineers are super proud of.
Do not let them watch this video.
The problem I see with this idea longer term is that ye it probably removes smells and stuff, but I have doubts about things like microbes and such. They even regularly get samples to look for such things(amongst others) from outside the ISS.
Step 2: vacuum degas the room to remove vacuum pump oil vapor coating all surfaces
This is really interesting to me because I have family heirlooms ruined by 30 years of indoor smoking, and I want to destink them.
Try an ozone generator. They are magical for removing smoke smell from things.
@@JamesChurchill3 gotta be careful with ozone, it can tarnish things really badly
ozone and this together will probobly remove just about any amount of smell, the problem is the tar deposits from that too. they might cook off, but I'm not sure what would remain (and how that substance will affect the object, or how it would be cleaned. it would suck to try it on a figurine and suddenly it all pools on the face and needs acitone to disolve.)
Like anything, DO NOT TRY IT WITH AN HEIRLOOM FIRST.
Find someone else that smokes and borrow a replaceable object to test the process on
Google up "laundry pulling." Do that and then put them in a bag with an ozone generator. You need to buy a decent size ozone generator, but the combo of those things WILL work.
Plus, the ozone generator works great in cars, especially to get that moldy air conditioning smell out.
I can confirm that this works. I could not smell it at the end of the video either. Though, keep in mind, I forgot to smell the video at the beginning.
Bro you have no idea how much I love this comment

In space, no one can smell you smoke.
Ironically, reportedly the outside of the ISS smells like smoke. Search terms are "what does space smell like" IIRC
@@ThePlayerOfGames is that because of the RCS thrusters that are used when docking?
If you’re in space and you smoke, but nobody sees you, then did you really smoke?
"In space no one can smell you scream"
This would go hard as fuck as a caption on an image of an astronaut smoking a blunt
I had a friend who purchased a rare book that ended up coming from a very smoky home. The book reeked, but there was no chance of getting a different one.
I bought several bags of activated charcoal designed for absorbing smells in closets. I placed those along with the book in my vacuum chamber, and pulled a hard vacuum. To help speed things along, I also shone a heat lamp through the glass lid.
After a couple of days, I removed the book, and it was totally scent free. All the old cigarette smell was completely gone.
And that was probably the better method than washing it…
That's a great idea! Gonna have to keep that one in the back pocket.
Can I do it with a car? I need a big vacuum chamber 😅
@@rkan2 😀 I was thinking about that, too. If we seal the vents, then maybe we can do it.
@@eugenetswong I guess most of the smells come from the fabrics on the roof, mattress and seats so if you can bag only those, you'll probably make a good effect.
Mild heating to increase the vapor pressure will greatly accelerate the evaporation, the Arrhenius equation would predict 2-3x faster for 10 °C rise in temperature. Also, using the fattest possible vacuum hose and fittings will increase the pumping rate in m3/s proportionately to the hose cross-sectional area until you reach the intrinsic rate of your pump. Almost all vac roughing pumps' flow rates are limited by the hose, not the pump.
So it’s basically the same as a compressor, but in reverse ?
With Joe Barnard you just never know what you're gonna get!
The reason this works is that most powerful smells are volatile organic compounds, or VOCs. Pulling a vacuum will pull all those out as vapors(and into your rotary vane pump's oil, lol), which will make it smell less. All the smoke, dirt, and everything else that can't evaporate, will still remain there. But your shirt will be extremely dry after a while.
So remember with a vacuum pump regular oil changes are important, old oil causes issues, and if it is black and looks like tar you should have replaced it a long time ago. My vacuum pump has it's oil changed about every third use, or if I see any cloudiness in the oil.
@@SeanBZAI'm new here, what kind of oil should be used in a vacuum pump?
@@lunaqueer For best results you get special vacuum pump oil, that has low VOC generation. However I just use regular mineral oil for refrigeration, which is a plain mineral oil. This works well enough, and the oil is cheap enough.
The oil I used was Reniso 63 or 32, a plain mineral oil, generally used in large refrigeration compressors as lubricating oil, and you can use any straight mineral oil there, though using the refrigeration oil is better, as it does not have any additives, and is meant to be run with refrigerant in it. first time I used the pump to dry out a wet system that oil went white in a few minutes, so stopped, changed it out, and carried on, needing to do it again before leaving the pump running overnight. Then it was dry, so refilled the system, and then took the pump and changed oil again, as it was then only slightly milky. Refrigerant oil is about the cost of regular mineral car oil, vacuum pump oil is around 5 times the cost. Even used the refrigerant oil to top up the car, as it is basically a SAE30 oil. Makes a nice general purpose oil to have around, does not damage any copper at all.
I can"t hear that music and not hear "guns, pickup trucks, or pickup trucks with guns on them" in my head
I’m glad I wasn’t the only one. 😊
I guess it accelerates the evaporation of any volatiles until they are gone?
It just removes volatile substances, it's not going to remove things like dirt and I wouldn't necessarily trust it to remove or kill bacteria. So, if you need to remove gas fumes from a shirt, this probably would help, but most other things not so much.
@@SmallSpoonBrigade Most species of bacteria will die in near-perfect vacuum with the exception of spore-forming bacteria such as Bacillus. However, these bacteria aren't typically associated with body odour so I think vacuum treated clothes could be a water efficient way of deodourising clothes in combination with occasional water-detergent washes.
Water efficiënt way lol? Running a vacuum pump for 5 hours could literally desalinate a cubic meter of water xD maybe at a large scale this can be done efficiently but in this example he burned 5 pounds of coal and evaporated 3l of water into steam just to degass 1 clothing item
@kapytanhook Do you understand what water efficiency means? It means the input of water is very low for the desired outcome. He never put any water in, therefore it is water efficient. He used a lot of energy so it is therefore energy inefficient.
@@Buckets41369 he didn't directly, didn't you read my comment how the energy that it cost not only has a water equivalent but also actually did cost water since our grid runs on boiling water
Here from Tom Scott's newsletter. Interesting watch!
He put this on the newsletter?? I'm subscribed to it but didn't notice!
Update: I think I got dropped off of the mailing list, because I haven't gotten an email in a few months.
Hi Joe - I just wanted to point out that the plastic handle on the manual release on your garage door makes it really easy to break in. It's easy enough to put a hook in a length of straightened clothes hanger and pull it from outside, just feeling around blind. But the fact that you have handy viewing windows makes it completely trivial! Just thought you should know (from someone who's come home to find their tools missing)
Isn't a solution for this wrapping the cord in a pool noodle or something to stop them from being able to get it over the door to pull on and making it really obnoxious to pull on with a tool? You still have the safety of being able to disengage the opener, but more security vs the attack.
Hmm, given bump keys will get you through the vast majority of home deadbolts in seconds, I don't think the garage door is the weakest link. Ultimately if someone wants to break in and they've prepared tools, they can break in (unless you take extensive precautions).
@@henryptungThe garage door string doesn't need prepared tools, just search trash cans for something long and flexible
@@henryptung Yes bump keys exist, but still not a good justification for choosing not to address a really fundamental security deficiency especially when the fix is so easy. Like I said, I've had my garage broken into this way and they didn't bother messing with the front door lock or the rest of the house at all. And why would they? Garages are easy to break into and tools are extremely easy to sell.
Some people live in places where burglary doesn't happen. Being a popular TH-camr does remove some of that advantage though
“Now we’ll get it set up” *tosses jacket into bowl*… now this is a tutorial!
Does that mean that astronauts could hang their dirty laundry outside the space ship and they will get cleaned?
No because space smells like burnt metal
And also heavily irradiated.
@@coin777funny enough the reason space smells like burnt metal is the same reason a vacuum works to remove smells from clothing. the smell actually isn’t from “space” itself but from the off gassing of volatile compounds from the walls of whatever chamber was exposed to the vacuum, which then mixes with the air once it’s been repressurised. you’re probably right that it wouldn’t work to clean clothes that way, unless you left the entire chamber exposed long enough for ALL the volatiles to gas off which probably wouldn’t be practical
Wow I love hearing a dad say “besties.” That was restorative.
1:11 The earliest reference I personally know of is in the Heinlein story "Misfit" that was published in 1939, but I would not be surprised if the idea predates that.
Super cool, I never would have thought of that. I also think there may be some value in having a pumping effect, i. e. repeatedly pulling a vacuum, rushing in air, and pulling it out again. Because under very high vacuum the last molecules won't find their way out of the container. For that you'll need a turbo pump. Bringing in fresh air and pumping it out again provides a current for the more clingy molecules to be pulled away.
Could you just leave the valve open a bit on the vacuum chamber?
Smells are mostly volatile compounds, meaning they easily evaporate from the object to get to your nose. If they evaporate quickly in air, they'll do that even faster in a vacuum.
next question is how does it work for drying washed clothes and what's the energy consumption comparison between that and a dryer
What if you carbonate milk and then decarbonate said milk
The carbonic acid curdles the milk *rapidly* and that is a non-reversible process
I did it once as a kid. Got two water bottles ran a hose between them, but water and dry ice in one, and then the fluid I wanted to carbonate in the other. Of course the whole thing went under pressure but it was neat how the pressure would drop as you shook the bottle you were carbonating and the CO2 would dissolve into it. You had to mindful of course to manage it. From what I remember I tried:
-Milk
-Kool Aid
-Orange Juice
They were all NASTY. Especially milk. I came to the conclusion that to make soda taste as good as it does they have to add a lot of sugar to it, and of course, they do.
@@Chazz155511i mean, plain and lightly flavored carbonated water taste good, and sugar free too. It's gotta be carbonic acid reacting to something to make it taste bad
You will still get prostate cancer from the dairy.
The first person to learn about this took the phrase "vacuum cleaning" literally and just thought this was how it worked.
Ummmm… if this is about moisture removal, then the myth test is not done :0)
Wait for the garment to equalise to ambient moisture and then do a smell test?
Holy shit though, quickest clothes dryer ever…
@@teabagtime Now that is a fair point. If you don’t care about crinkles, that’s definitely the way to go 😂
Joey B myth busting could be a banger of a series.
Stunning and brave to stand up against the vacuum units. I lost my mind when I first learned that.
"Car is in boost, 10 pounds per square inch. Great. So when I let off it gets down to...-12 PSI?"
Nope sorry INCHES OF MERCURY
True. We do some vacuum tech in Uni. While Pascal/Millibar is the norm, mmHg aka Torr is also wideley used and I hate it.
Pressure? I got pressure, what pressure ya want? We got inHg, mmHg, inH2O, Pascals, Torr, PSI, PSIg, Nm^2, atm, bar. When I built my first high-vac setup, I swear, I had to use ALL of them.
I love this channel.
Interesting. Perhaps this could finally clean my old Fazoli's uniform from my first job ever. Dozens of washes and sitting since 2003, it not only still reeks of that hellhole, it still feels greasy.
Thanks everything you do
Now you just have to put it into an ultrasonic cleaner to remove the stains :-) Cleaning in space: put your clothes into a laundry bag and let them float a bit in the vacuum of the space. it is like put your washing on the line in the garden.
You'd end up washing away the pants too eventually
Legitimately useful. I have a very warm jacket that permanently smells like campfire and I essentially only wear it camping because of the smell. I've washed it over 5 times, in a row, I've soaked it in vinegar, but it still always smell like campfire. If I ever get a vacuum chamber I'll for sure try this haha.
That was cool. Thanks for doing the video.
Perfect for wool and linen!
Just a spray on a little mold release to remove those stains
Floating brain in a jar and master of the third dimension John Carmack would try and vacuum clean his clothes
I feel like this is where I should say something like "this would be great if I had a vacuum chamber lying around". But then I have to fess up and admit that I do indeed have a vacuum chamber lying around... I mean who doesn't am I right 😅
The problem with putting your clothes in the air lock is much of the oils and moisture from your clothes will stick to the outside of your spacecraft and it's sensitive instruments.
This would be great for something that's not practical to wash, like a hiking backpack which is impossible to wash, yet gets covered in stinky sweat.
I was thinking the same thing but for shoes
It makes sense because you are allowing all the volitile compounds which make up smell to boil off. Smoke from the fire is probably 2 fold though, both volatile compound and micro carbon/partially decomposed cellulose. Since many of these dirts and such feed the bacteria that create smells from your body. I wonder if this vacuum method would result in clothes that return to being smelly faster. Its like planting in a nutrient rich farm.
When you think about what smell is to begin with, I think it makes sense. In order to smell the clothes must be off gassing compounds that you are detecting with your nose. By leaving them in a vacuum, you increase the rate of off gassing, thereby accelerating the process until the contaminant causing the smell is exhausted. Or to say it differently, it’s like accelerated airing out that you might do with a jacket that smells like campfire.

I'd be very curious to know if some smell returns as the clothes and scent particles reabsorb moisture from the air or sweat.
asking the real question!!!
Yes, i want to see you talking to Traffic Cone. Also yes, i also want to see you putting clothes on a stainless steel thing you use to make cookies.
You should try to build a freeze dryer. You have a lot of the parts alredy with that big pump and vacuum chamber. Also if you own a bakery you could find a use for one im sure. Would make a cool video.
I would have thought it was about killing the bacteria that live off of sweat, not actually vaporizing the compounds. But that makes sense. This video just went from "that's interesting" to "that's something I should play around with" in less than 5 minutes. Also, I'm impressed you were able to go 30 minutes and then 4 hours without using your phone OR getting a text about your extended warranty.
I initially heard "this smells like HPV and campfire" and I was very confused
VERY cool!!

Unlocked new ability: True Dry Cleaning
John carmack cannot be stopped
Joe, serious question - can you please put some kind of high density Styrofoam (like the kind found in helmets) in the vacuum chamber and report the results?
I remember seeing the @AppliedScience video "measuring human digestive efficiency" from three years ago. vacuum does a surprisingly good job of removing the smelly stuff.
I finally have a use for my vacuum pump...
Follow-up: Expose de-gassed garment to humidity and retest...
Carmack will be our first cyborg. i love that man
this is great for clothes that cannot be washed due to complexity like costumes or specialized clothing
and as long as its not stained its viable
What a great video title
Something something camp fire something rocket propellant.....
That's weirdly cool
Im currently watching this and i just ran out of laundry detergent and i have a vacuum chamber for reasons unknown. I didnt search this. The algorithm knows my routines
I do wonder if you sprayed the article with some sort of safe and cheap solvent like cheap warmed vodka, or similar and then squezzed off any excess if you could get off more and end up with a dry and cleaner object… i have used a vacuum chamber for filament drying of grumpy plastics like nylon and it has been pretty good.,
This is what youtube is supposed to be, good vid
ANOTHER USE for Our Harvest Right Freeze-Dryer! I have Favorite Hats that Need Cleaning! Besides Preserving Our Favorite Cuisine for "Power Out Drills", I use the Vacuum (to equivlent 120,000 Feet Altitude) to Make My Own Vacuum Tubes, and to Preserve Coffee Beans (I am a Coffee Snob!)
Everyone needs a good pair of shop jeans, and I need a pair that smells like your bakery. 🌠
You can also spray your clothes with vodka and it'll get rid of the smell
I vacuum degassed a bunch of comic books and magazines before selling, work good, got all the musty smell out.
This would be nice for souvenir graphic shirts from conventions. They are irreplaceable and really don't survive being washed.
The perfectly white T-shirt contrast nicely with the dirty raggedy jeans
Can you test this with those vacuum storage bags for like a week or something
Engineer here: Reducing the pressure reduces the temperature at which things vaporize. You can add some heat to vaporize more, faster. As the materials vaporize off the vacuum pump pulls them out. Also, I highly doubt you hit 30"Hg vac as that's true vacuum (unless you're deep in a cave), which is difficult at best. 28"Hg is about as good as you're going to get with a setup like that, at least at sea level. It would be interesting to see how it works if you were to dampen/wet the clothes first.
I suspect - though I don't have a vacuum pump to test this - that the vacuum pressure in the chamber is indicative of how much remains of the smelly compounds. The whole point is to get them to change into a vapor, and If there's a lot coming off, the vacuum pump will struggle to remove them faster than they come off the clothes. Once the offgassing slows down, then you'll see the pressure in the chamber really drop.
Just be aware that, like, _most things_ will continue offgassing way longer than you probably want them to. For example, spacecraft hardware has to be designed carefully because a lot of plastics and lubricating oils will simply evaporate in space. The vacuum these pumps can reach is much less intense, but I'm not sure it couldn't become a problem.
I have a vacuum pump and chamber in my home but no washing machine, so weirdly this video might actually come in handy someday
can confirm, does work. washing machines are better and more efficient though, vaccuum chambers don't require detergent or water but use way more energy. great for drying compared to most resistive dryers however.
Dryers should use negative pressure to decrease drying time. Bonus points if the whole thing implodes.
My guess would be it works by encouraging whatever particles and molecules that are causing the scent to leave much faster because they're being pulled away from the clothing
heating it works well aswell. a dryer will get smoke smell out. but vacuume AND heat would probably work great !
If you want to go down a rabbit hole, there’s also the morus zero, circa 2019 or so. Vacuum pump washer/dryer kickstarter scam.
I think it’s what kicked off a lot of public interest in the concept/ debunking or proving aspects of it.
Removing volatile compounds (if you can smell it it’s from a volatile compound) by lowering their boiling point. And boiling them off. Running vacuum continuously will expel quicker
I don’t think it would work for my hat. The vacuum would probably reject it.

Raw denim heads gonna go wild with this.
Why? this doesn't solve the problem. If you go much more than a week or two without washing denim, you start to see issues with it degrading due to dirt getting in there and damaging the fibers. And, in my experience, the denim doesn't really even start to smell for at least that long.
Guess that sweatshirt isn’t making it through TSA anytime soon
Now I'm wondering how astronauts wash their clothes. They just throw them in the airlock?
TIL They don't. Dirty clothes get put into the resupply ship that burns up on reentery.
@@Rouverius There's issues with cleaning things in space. The only real alternative would be dry cleaning and that has it's own set of issues.
I think something like this would be awesome for homeless shelters or similar places like that. With only 1 change of clothes the time spent washing and drying normally wouldn't be feasible .
Shooting my socks in space.
I love the smell of campfire
I wish there was a control set of clothes too. maybe just having it sit there for a few hours was the reason it lost the smell. but yeah this still seems plausible
it would take less time to wash them, but its still interesting.
What if you do one of those black ice Lil tree car fresheners? 🤔
Ooh. THIS is it
I hang up anything that doesn’t have a visible stain, and have an air filter (with activated carbon) in my closet, and it comes out smelling fresh.
