Does water boil or freeze in space? Maybe a little of both? if you like this, you can support this channel directly here: https://www.patreon.com/Thunderf00t or visit my amazon store: https://www.amazon.com/shop/thunderf00t
One of the most Mind Blowing Awesome demonstrations I've ever seen !!!!! Ice Cold !
It never crossed my mind that it would freeze
Me either , that was awesome, I knew that in space, water going from atmospheric pressure to vacuum in an instant would cause an extremely rapid loss of heat. He used the best method to show this.
You can use a similar method to get solid nitrogen. Everyone knows liquid nitrogen is cold... But basically needs a vacuum and special set up to get it to freeze.
I do wonder if the vapour pressure speed would be limited by practical effects of the diameter of the tube over really long lengths?
And would the amount of actual energy transfer through the tube (and hence available to be converted by a turbine) be directly proportional to the diameter of the tube?
Got any feel for the practicalities of this Thunderf00t?
@Benny no, it would determine the flow speed. And that would be changing the temperature not the distance
This video series is just one big joke. It's one big hunt for the worldwide stupidity.
Remember the goal is to get cheap energy from this! @thunderf00t was pretty specific on that.
@AlucardPawpad ClownWorld he doesn't have a return and heatpipes don't operate in the solid phase. But it's basically the same thing so you are correct.
When I first saw this, I thought of why not using sea water to extract the energy from as an assist to solar power (some would be used to run pumps, etc.) but as with all similar ideas, someone has already come up with it of course. http://www.otecnews.org/what-is-otec/
The site looks legitimate enough. Further researching reveals that plants using this technique do already exist, the open cycle type is more in line with the the 'hydro-vac' system. https://en.wikipedia.org/wiki/Ocean_thermal_energy_conversion
Even though I'm no where near intelligent enough to understand all of what is being said in this vide. I seriously do love your direct method of education, and the personality you put into it.. Also it might mean very little coming from me, but I have to say thank-you, so very much for your contribution on society as a whole.
@Dyionisis Yhe horned one hahahaha ooh so im not the only one thinking he has some narcissistic behavior every now and then. pretty weird i thought for someone that is smart enough like thunderfoot to understand people usually dont like it to much when they brag allot about them selfs. anyhow i do like the videos :)
Thunderf00t genuinely likes doing these science videos from what I can gather.
This video wasn't as in depth about explaining the particulars about what was going on and why, but most of his vids do a lot to explain why a thing is, or can't be, or how a phenomena would be if scaled up/down where appropriate.
@ShadowFoxSF well he is a scientist after all and yeah, he really appears to enjoy these science videos. I was pretty lost on this video though
What is so complex about this?
Proto Propski Easy, he didn't find a cure for cancer.
Yes (it boils till it freezes)
Except evaporation isn’t boiling.
@Grunchy It's the same thing, just different rate
@Sikh Atheist, not exactly. In different conditions I think you can get boiling that's slower and surface evaporation that's faster. The difference comes down to surface evaporation happens on the surface, and boiling is when bubbles form and grow within the liquid.
@JNCressey I am no expert on this, but wouldn't having a mono layer aka surface evaporation be slower than having the entire volume available to contribute?
TF's criteria for whether to do a video: "Does the premise give me several excuses to pronounce 'water' weirdly again?"
How do solar roadways and Anita fit into this?
Some say his beef with Kent Hovind was really over water rights. Who had the right to pronounce "water" in their own weird way.
You might boil / freeze but no one can hear you scream.
@seigeengine I don't give a rat's arse about your circle. Just because in your circle you're accepted to dress like a moron doesn't mean you suddenly stop looking like a moron to the rest of the world, but do feel free to keep telling yourself that. After all, it appears to be the only thing by which you so fond of declaring yourself special. Although I would rather say "special", in this case, but what do I know. I'm just one of a million people on the internet who just happen to pass by yet another orthographically incompetent anglograph who can't tell his ei from ie. Carry on. Moron.
@Anvilshock I made this username when I was 15, and I'm 24 now. Any thoughts?
@SinBae depending a bit on how close you are, i though, the air you put out when screaming/carries the sound. but how far will it reach.
@seigeengine You sure are doing a lot of jumping right to vacuous stock insults for someone who just a second ago at least tried to bring forth any arguments in favour of his decision. It must be that you have run out of your already limited pool of delusional reasoning. Well, that didn't take long. Not that I expected that it would.
@seigeengine and this air could conceivably carry the scream... interesting...
Science, getting in the way of free energy since... err... science
Lol I get it 😂
@Creamy Pasta no humans have abused science . Science is innocent.
@Ronald Brown Just like animals are innocent, eh?
After hundreds of years of people trying to build machines that make energy for only a capital outlay only solar worked. And that only worked half the time and in a single layer. Modern technology has improved, there are solar panels three layers deep in laboratory settings doubling their output! But they still don't work in the dark. I suppose the laws of thermodynamics have been confused but never broken enough times that some folks are just about hopeful enough to try condensing water vapor in exaust to crack it into hydrogen to burn it in the engine for fuel without understanding the heat of the gas from condescension is wasted heat. Although it raises a question. I keep hearing folks saying pouring water on a super large fire can cause hydrogen to be liberated and cause explosions.... Surely not unless aluminum or something super hot is burning.
@Glen McGillivray Triple junction solar PV is nice but check out the nanoantenna design from NovaSolix aiming at near 90% efficiency: https://www.novasolix.com/technology While being very cheap too!
Friend: "How do you know the glass isn't just conducting the cold"
Me: It would freeze where it's touching the glass first, not where it's touching the air... wish he'd show thermal.
TF shows thermal in video
Me: ... and there you go.
Thunderf00t: Now, go back, say the complete opposite of everything you've said in this video, and COLLECT LOTS OF MONEY!!
He did that last video. Hopefully the moron-money will pay for more science videos like this one.
Spoiler; it boils until it freezes.
Spoiler: that's not why I watched the video...
Like opening a bottle of liquid carbon dioxide
Freezing is temperature dependent, boiling is pressure (and temperature) dependent-apparently.
then it sublimates
@Mike Wood That's right
Why would you use the odd non-standard unit "mn J/kg" (million joules per kilogram) instead of simply using the SI standard "MJ/kg" (megajoules per kilogram)? 🤔
He also forgot to say “kilogram-mole”, because all thermodynamic eggheads just love to go on and on about all the kilogram-moles they’ve racked up in their mum’s deep freeze.
@clitiss wood yes, that is exactly my point. Thanks for fleshing it out a bit. So since the underlying unit is the same, there is no difference, except scale. Typically when you deal with very small or very large volumes, you adjust the scale to fit, but the underlying unit stays the same. The OP says there is a difference and there is not.
@Aaron Lowe I didn't say the values weren't equal, I questioned why you'd use the unusual, awkward, clumsy and superfluous "million -Joule-kilogram" descriptor in lieu of the more normal, succinct, accurate, and standard "Megajoule-kilogram" ...
@brtle So, you prefer to see a number written as 0.00001 instead of 10? I don't understand how that helps. It's more unusual, more awkward, more clumsy, more superfluous, less succinct, and no more accurate. Who gives a fuck about standard if it's harder to read?
Maybe the million is part of the number rather than the units 🙃
but would Elon musk freeze or evaporate in a vacuum tube?
The real question is, should Space x now use water as an evaporative coolant for the Starship or methan. I mean, instead of approximatly 19 tons of fuel they could simply use around 600 kg of water as coolant, they could also use it as a part of the radiation shielding and for thermal management (as the part of the hull, that is pointed to the sun, is much hotter than the other parts and therefor causes stress due to uneven thermal expansion), water could do triple duty so to say :D.
@TheReaverOfDarkness actually as the air and your saliva expelled from your body, you'd fall unconscious almost instantly. And the air expanding would freeze the insides of your lungs and mouth dropping your temperature by a bit. And if you survived the initial experience the insides of your breathing systems would likely be bleeding and you'd have a very slow unpleasant death as your lungs filled with blood. Of course odds are you'd die before that if it was a sustained vacuum.
@Chaos Shepperson Actually there was an astronaut who was exposed to vacuum for several seconds. You can read about what happened. In short, you're only partially correct.
You can theorize all day about how it might go, but you can't be sure you've thought of all of the important factors until you try it.
@TheReaverOfDarkness well the ones i found said you might be ok for 15 seconds and some animals survived near vacuum Condition up to 90 seconds though unconscious after about 3 seconds and usually involved explosive bowels. So ok if someone was holding your hand you might live. And maybe if you were well, prepared for it you might hold your breath etc. Id love to read your article but the ones i found sounded altogether negative to the experience.
@Chaos Shepperson It is pretty negative, but you don't die instantly. You lose consciousness in around 10 seconds, and it's uncertain when you die but probably within 30 seconds.
It varies greatly between different animals. Most likely some can survive vacuum for minutes or hours, but any that breathe will find that difficult.
Discover how one man learned to cool his drinks instantly with one simple trick. NASA scientists hate him.
LOL
A simpler way would have been to just put them in the -50 deg jar and do away with the elaborate glassware.
@Mike Wood That it's an elaborate machine, that is the joke!
drinking game, take a shot every time thunderfoot says "unbelievable" or "amazing"
I wish we had done experiments like this in school! I remember my science books having cool lab workshop instructions at the end of each chapter and I recall being so excited only to be crushingly disappointed when the teacher said we weren’t going to be doing them. The closed circuit with a light bulb workshop was one of my greatest heartbreaks.
Yea a good chem teacher is everything. I lucked out in 9th grade i happened to get the really cool wacky scientists who wasnt yet jaded and he awoke a great curiosity in me for chemistry,so much so i went from a strait f student to tutoring algebra so that one day i could do that stuff for a living. That is why american schools fail so miserably they base teachers on tenure instead of a meritocracy and the student suffer dearly for it.
Also nice heatpipe (or maybe coldpipe in this case) demonstration
Physics is fun :D
- You might not explode in space, but you'll certainly vent some gas... Paaaaarp!
Apparently Physics 'are' fun, according to US linguists.
@Snark Skent they can say what they like about their own language - as soon as they get one ;-)
3:50 woah. So you basically built a heat pipe with water. Cool!!!
God i love practical science,especially chemistry. I wish i had not dropped out of my inorganic chemistry major 😭
this is more physics than chemistry
that is exactly how vapor chambers/heat pipes work
0:39 damn. That big forearm and bicep tho.
He blinded me with Science!
How to transfer cold over long distances in a vacuum. :D
I'm glad you've moved on from religion and the mentally ill for the most part, but this stuff is elementary tier. Keep up the good work though.
It breezes. Then it foils.
A: water boil on vacuum
and freeze when it boils
That water evaporated faster than Theresa May's hopes of a clean Brexit Deal.
To soon?
Awesome, Thunderf00t can distill using ice!
Question: normal distillation (e.g., to separate fluids) is based on differences of the boiling temperature. However, this "ice-distillation" seems to be based on differences of vapor pressure. To me, this sounds like something very interesting to consider for separating fluids with similar boiling temperatures (but different vapor pressures). Ideas?
Thank you for showing the thermal camera.
In case anyone wanted to be like "well the glass is cold"
Neat demonstration. I was worried the whole time that there might be broken glass by the end. I'm no scientist.
Brainiac host gives Thunderf00t a trophy
Thunderf00t: "I can do science me"
I feel that, ironically, you're the first dude who made something useful out of Musks ideas. Tubes and vacuum etc..
Thunderf00t,
How would you keep this reaction going building a hyper loop in the ocean to generate energy? I’m assuming you have to pump warm water towards/ away from the poles regularly to keep the reaction going, right? Will you be showing more on this in a future video?
Yay science vid
Me screaming "Noooo" at my phone when he said it was a story for another day. I'm hoping that day is tomorrow.
This series turned from "oh, so you just made a heat engine" to "wait what? that's actually some cool science here" in like half a video. I'm looking forward to your future ones :)
I love these experiments. How I wish my science teachers had been even half as interesting... I think I'd have been much happier if I'd been encouraged to apply myself to physics and mathematics, maybe even chemistry (sorry biologists but I was very squeamish back then. Not sure I could dissect an eye now! Though hearts et al wouldn't be a problem after all the years of feeding a hungry hubby and hungrier kids! I couldn't afford to be squeamish when they were young lol. Plant biology would be my limit). I might even have become a geologist, which is my greatest scientific love. Sadly things have worked out so even studying now it couldn't happen :(
In the meantime, please keep doing these wonderful videos. They're a real joy to watch, partly because of the pure science, but also because your love for experiment is infectious :-D
I am sitting here, literally with my mouth open. That was "cool"
0:00 before watching, I say boil
Edit: well... that was a weird experiment.
"Throwing a glass of water out of the window" (in orbit, dare say TPTB would have something to say on that idea, space junk and all).
A fellow scientist chiming in here: You might be interested to know (if you don't already) that in organometallic chemistry labs, this kind of transfer is done routinely as a way of stripping solvents out of a solution without heating them, since a lot of the compounds we work with become somewhat unstable if heated much above room temperature. We do it in a similar way to the apparatus you show here, albeit with more of a temperature difference: Liquid nitrogen is used for the cold trap, which enables the condensing of organic solvents, most of which have freezing points well below that of water. (There are exceptions though, such as benzene or cyclohexane, which both freeze at about 6 degrees C.)
If we aren't too concerned with keeping the solvent which is evaporated off, we typically also use a dynamic vacuum to speed up the transfer, with a second cold trap just before the vacuum pump to catch any solvent vapours which don't condense in the first one. However, a static vacuum transfer is still done for "distilling" special NMR solvents (organic solvents with all the hydrogen atoms replaced with deuterium), since these tend to be rather expensive, so you don't want to lose any vapours down the vacuum line.
When he mentioned "story for another day" did there come set story in a newer video?
Next experiment: Test with boiling hot temperatures.
I bet you'll get an even faster transference of energy.
And then you could, in effect, make a Peltier ENGINE just running off of vacuum, water, and temperature.
During hot summer I usually sip my drink with force running it throught my front teeth so you get a colder sensation. I also notice the drink was getting colder and water condenses outside the glass. You should try it.
While Mr. F00t is usually interesting and often funny, AWE remains my favorite of his expressions.
Water travelling at the speed of sound. Zomg this means the Grand Canyon was formed within about five minutes. ;)
"wwater"
interesting accent
I really wish I had your videos around when I was in high school, would saved me a few hours of researching and reading. Best demonstration I've ever seen for a somewhat hard to understand concept.
Don't you just love trick questions?
The answer my good boys ...
Is always C, both.
When in doubt, just enter C bruhs.
What is the “speed of sound” in a vacuum?! I guess he means about 330m/s, which is roughly the speed in 1 bar air...?
Also a person in space wouldn’t just freeze or boil at all. There’s nowhere for the heat to go. You could argue the person would die of heat from sunlight, maybe...?

@hpekristiansen
More likely the hiss of slowly escaping air, the popping of the ears as the pressure reduces, the futile search for the source of the leak, the desperation in the passengers eyes as they gasp for breath......
Elon Musk suggesting they send in a miniature submarine....😉
Senseless Inductor - 2019-03-10
Yeah, it is this moment when you realize that just because people watch Thunderfoot, doesn't actually mean they understand the science.
Wordavee1 - 2019-03-10
@Senseless Inductor
Are you for it or against it??
Chris Davies - 2019-04-05
No such statement will ever be spoken. No sound can propagate in the vacuum, and certainly not into a magnetically levitated coffin within a hyperloop. The 38-Gigajoule air hammer produced by a 2-metre hyperloop advances at just short of the speed of sound, away from the breach. For reference the MOAB, the most powerful non-nuclear weapon yields 41 Gigajoules. And there are two air hammers on each ruptured hyperloop. The coffins are turned into dust when the air hammer strikes them, and it also explodes the tunnel at that location, as well. The devastation at the stations, when the hammer hits the airlock will see concrete chunks falling a couple of kilometres away.

@Feeds Ravens repressurizing takes a few dozen seconds at most, it's not like there's a single inlet on one end of the tube...
