Sadly not enough on youtube, i mostly see americans only use the imperial, which is no problem, but if they dont even "translate" it to the metric it is kind of insulting.
Americans don't use the imperial system. They use the English system which is not the same as the imperial system used in England before it went mostly metric.
@Squad 47 jesus why so toxic. ice dispensers obviously dont make ice right on time whe you press the button to give out the ice. its already frozen and stored then. then other ice is made to refill the storage room
I have seen this on graphs, and i just kind of took it for granted, but seeing it actually happen with my eyes is something completely different. A deeper understanding. Thanks for the video and your effort.
He's quite obviously a Terminator cybernetic infiltration unit, series T-800. This would also explain his surgical implementation of a magnet as a replacement for a burned out wrist servo.
Respect for using celcius. Glad that some youtuber understand that statistically more of their viewers use the metric system, rather than the nonsense crazy system.

Yes, but riding a horse everywhere wasn't nonsense either, until the car was invented and perfected. Now it's nonsense. By that i mean the act of using an inferior system when an objectively superior system is available. Not that the inferior system isn't based on anything.
if this were pure water, you would've been able to see the frozen ice turn back into liquid at 0.01C and 6mm of Mercury but it was tap water so it had many ppm's of salts
I work in the refrigeration industry, working on huge chillers for commercial size buildings. With refrigerant we also boil off as super low Temps under a vacuumed pressure. Love this channel! Keep up the great content!

Cody I've been watching you for about 2 years and you've never failed to excite me every time please never stop making videos I love watching them so much your definitely my favorite TH-cam and keep marking amazing videos
From the video i'd say it's a lot quicker because he had the whole thing converted to ice after 12 minutes, whereas it would have taken probably more than 1/2h in the freezer.
People are not born with knowledge, *everything* is new information to *everyone* at some point in their life. Humility is vital to learning. Remember that the Dunning-Kruger effect applies to you as well.
Cody'sLab hes got a valid point but idk y for some reason i half expected you to drink the water and get iocaine poisoning or something. if you get reference leave a like
The freezing phenomenon is quite common and is easily anticipated. The overarching relationship is the vapor pressure curve. If at a certain temperature and pressure, liquid water should be a vapor, the liquid will suck energy out of the water to vaporize. The huge latent heat of water causes the water temperature to drop. But the vacuum continues to go down so the steady suckage of energy continues until the water is frozen. Then sublimation takes over. Most liquids exhibit this phenomenon. But water has the highest latent heat of vaporization so the effect is more dramatic. I am most glad that this experiment does not involve mercury. One day you may get madder than a hatter.
Your explanation is not wrong, but you some funny language that convolutes the thermodynamics a bit. Maybe I can restate your point so they understand. The process of water boiling is exothermic, it requires water molecules with enough kinetic energy to leave the bulk water and surface tension layer. Since temperature is just the average kinetic energy of water molecules, the fastest moving molecules will boil first, leaving the remaining water with a net loss of kinetic energy so that it's average temperature is now low enough to freeze.
Yasin Omidi the amount makes the poisons and the medicines. Many poisons are used in lower amounts as medicine eg curare in surgery. Hell many fruits have cyanide or cyanide like compounds so all of us have eaten cyanide most likely at some point
+Eagle 367 Pretty sure you're thinking of the fruit pits (apple seeds, peach pits, etc.). Also the phrase is "the dose makes the poison," I think you just quoted a song right there ("The Difference Between Poison and Medicine is the Dose" google it). But otherwise you're right. Plus, not all cyanide compounds are dangerous. Cyanocobalamine is a cyanide compound, and it's better known as vitamin b12. (This is why hydroxycobalamine is used as an antidote in France; it binds with the cyanide group in, say, hydrogen cyanide, and forms b12 instead). Prussian Blue is still commonly used as a blue pigment (that's why it's called Prussian *Blue*, not Prussian Pink or something) and (as Cody mentioned in a different video) is used as an antidote to thallium. Citation: Molecules of Murder by John Emsley. And wikipedia. Also, I can't find the cyanide video that everyone keeps talking about. I want to watch it, but not nearly as much as I want to explore the comments section because I'm sure it will be an interesting one.
Wow that was way cooler than I expected. I knew a lesser atmospheric pressure would cause water to boil at a lower temperature, I had no idea how far you could push it though! Awesome job.
We used to do something similar to this, though it never froze for us. We used to seal water inside a glass jar and turn upside down. Then we would put ice on the top, this would cause a drop in pressure and the water to boil. Just an odd thing we used to do.
Nicholi Martin the ice cube made the air shrink enough for the dissolved oxygen In the water to come out and regulate the pressure but in this the air came out to regulate the pressure and got sucked out making there no barrier I guess and the water froze
It did pull the oxygen out, but if you have enough room in the jar with enough water you can still get it to boil, just not freeze. I just thought I would mention something fun I did years ago for my nieces.
Hey I don't understand why the drop In pressure in the video caused the water to freeze. With looser bonds, the molecules should be more active and be able to boil more. So why did the drop in pressure cause the water to freeze? It's been about 6 years since I last took chemistry
The boiling point just means the energy it takes to go from the liquid phase to the gas phase. Since the more energetic molecules are going into the gas phase, the remaining are of a lower temperature. That is basically why.
I heard of a planet that was discovered (the Thoughty2 video about 10 strange planets), that mostly consists of water and in a depth of X km under the surface the pressure forces the water to become ice, while the temperature is around 600°C or so. The ice is called ice X (ten) and is probably as hard as rock (sry if these information are not accurate it's a while since I watched it)
So could you make some breathing aparatus with air from lungs filtered through this high pressure water (That has been enriched with oxygen ) ? Just like Acetylene = Acetone + Ethyne < I think :) Sorry for bad english
This was pretty interesting! I don't know why it never occurred to me that water would behave this way. I would have assumed that the water would just boil off until it was gone. It works just like the refrigerant in an air-conditioner or fridge. Only instead of compressing a gas to make liquid, you're depressurizing a liquid so it gases off... AND FREEZES. Fascinating!
Isn't a perfect vacuum only theoretically possible? Even in very deep space you will still have a certain number of Hydrogen atoms within a meter cubed.
That depends, in a small enough volume you can't *fit* an atom, the lower the pressure the less likely any given volume is to contain anything at all. In the lab it's possible to make milliliter perfect vacuums easily enough.
Mostly you just classify the kind of vacuum by the pressure left (normal, high, ulta high, etc.). So in a classical setup you will mostly just say it has a strong vacuum with 10^-9 bar or so. But if you try to push the limits with like very small volumes, you might crack the usefulness of the difinition of vacuum. Even if you manage to get out all gas and other real particles, you end up with vacuum fluctuations and thus virtual particles (quantum mechanics) which are basically pairs of matter and anti-matter popping in and out of existence. Those are always there and also can do work (see casimir effect), even though you classically (newton mechanics, thermodynamics) have a perfect vacuum. So if you try to be precise you have to check definitions and their purpose. I hope that helped^^
Hi Cody, In a previous video you mentioned that mercury has a vapor pressure as well, since it too is a liquid, although much lower than water. Would you be able to boil liquid mercury in a similar setup to this one? And eventually get to solid mercury?
For that I would really have to put it in space since the vapor pressure at the triple point is something like 10^-12 torr. But yes it would be possible.
@kurpingspace productions I think the point of what he was asking was not whether or not mercury could be frozen, but whether or not it could be frozen via the same method as in this video, by way of decreasing the atmospheric pressure around the mercury.
I was actually thinking of checking out this channel recently. Stumbled apon this video looking for something else and didnt realize it was codys lab until the vid started. What a pleasant surprize. Ive been watchin since back in 2010ish when there were only like 50k subs. Nice to see this channel blew up. Good for you cody hope your doing well!
I've had this water / pressure question since I took physics in high school. If you had a pressure chamber capable of increasing the pressure inside above 784 times that of atmospheric pressure would there be a point where water becomes buoyant due to it's inability to compress significantly and it's density would be less than that of the surrounding air?!
This really made me wonder, In theory I think you would be able to, It would just be a challenge to make such a high pressure chamber along with some unexpected side effect that I'm sure would pop up. It would definitely look interesting though.
Substances have a critical pressure and temperature, which after that T and P are reached, the substance will be a supercritical fluid and exhibit properties of both liquid and gas. 784 atm is well past water/airs critical P/T so at that point, you would simply have a one phase mixture of water and air combined. Feel free to read more on the phenomenon en.wikipedia.org/wiki/Supercritical_fluid. And there are also some cool youtube videos showing the effect.
You could put a fine mesh wire fliter over the cup with the water in the chamber to avoid the small droplets from slushing out and covering the glass. The vacuum should still make it through just fine. Great experiment!
I know this is an old video but nice nonetheless. I used to work at a well known pharmaceutical factory. We made a vaccine called Yellow Fever, the process, without getting into too much detail, used a process called Lymphinizing. Basically freeze-drying the vaccine into a dry cake. They used a reconstitution method using sodium chloride to make it into an injectable. Really cool process to be seen first hand and educating. Thanks for the video Cody, learned a lot from working at that place.
The first AC systems were on railroad passenger cars. They used a steam powered aspirator to pull a vacuum in a chamber of water. The chilled water was pumped to cooling coils in the passenger compartment.
If the watch ran faster in a vacuum, then the seals and gaskets would have failed. If the gaskets did fail in a vacuum, then the watch crystal would literally blow off. This is sometimes observed by deep-sea divers. All watches that have been used in EVA's have survived (to my best knowledge and research). Which means that their gaskets didn't leak any internal pressure.
Electronic wach precision is governed by a quartz crystal inside. Those crystal are sealed in a small metal can since the crystal naked is very fragile. wach Crystal is called tunning fork crystal. It resonates at an exact frequency (like a diapason). Wach chip divides this reference to get seconds, minutes and hours. So, even when its true that there is sort of mechanical part inside an electronic wach, it is super sealed. The facts that make crystal drift are TEMPERATURE (heavy quadratic dependence) and vibrations (can even damage the Crystal). Also, the wach chip is not very tolerant when some properties of the Crystal change, so even when it coul drift tooo much, it will make the wach fail completely. Chip is also super sealed also. Like other user said, the LCD screen could be damaged but doubt the wach could get damaged. Almost every electronic gear around us use quartz crystals as time reference. Crystal are cut to a specific frequency. Ok, not very interesting ....but wach Crystal is working at 32768Hz (oscillates 32768 tmes per second). It a CLASSIC number for sure. Timekeeping in the computers use the same. Crystals eventually age and drift permantly every year (wach can get slower or faster ... just by a very small amount, like 5ppm). Computers have no probs since they go and adjust the time using time servers over internet. So do the phones. HIGH precision references for laboratory use CESIUM. Those ones are insane accurate and wont drift. Precision time could be derived from them
38911bytefree Not sure if this is also directed towards me. But to clarify I was only talking about mechanical watches, not quartz or tuning forks. Also my mention of "crystals" was in reference to the case crystal, the front glass of the watch in which you can see the moving hands, not the quartz crystals.
Dylan Greene Was general info kind of post, I am writting (I think it is still possible) my opinion on what I think is happening or not happening. Didnt read you mention about crystals, just read the firs and second comment I believe (didnt click see more). So, no worries.
Just so you know, high vacuum is classified as pressures from 10^-7 torr on, or a millionth of atmospheric pressure. You achieved middle vacuum, barely, impressive with only a mechanical pump. You would need a diffusion pump to get lower.
Actually 10^-7 torr or less would be considered Ultra High Vacuum. And to get to those levels not only a turbo or diff pump will be enough, but better seals and a clean chamber would be nice. :)
Anyone know what kind of force would be acting on that (perspex?) door? It looked quite thin and had a large surface area so when he was talking about a 'high vacuum' it seamed a little concerning. Then again it didn't appear to flex in and become concave or anything so it must have been all good. Is that some kind of crazy strong door or was the force a lot less than i'm imagining?
+J Paino That door seems to be about 1 foot in diameter. That's about 113 in^2 of surface area. And 1 atm of pressure equals to about 14.7 PSI. So, multiply both and we have about 1662 pounds of force. But it's not a complete vacuum so it's gonna be less than that.
Hey Cody i have a question i dont now if you could manage to do this but im wondering if you could pop popcorn in a vakum im wondering if it would be fluffy like it is or not or would it be even bigger ? si when it is not too hard for you to creat the heat or microwaves in the vakumchamber (since its a vakum i think we can left the microwaves a side) too pop the corn that would be totally awesome. Greatings from Germany keep doing your great Videos !
***** you are awesome ! I was wondering still a time what would happen is the air in the popcorn intermolekular so is it producing wenn it pops or is the air from the outside and what happens in the vakum it will be so interresting ! :))
I picked up a large old Robinair vac pump ages ago, with an absolute pressure gauge, but I need to pull more vacuum, for making Crookes, and Geissler tubes. I have a reliable source of cheap (free) helium, neon, krypton, argon, nitrogen and other gases. I am also running a solar torrefication chamber for baking wood in the absence of oxygen. The process mimics or at least gives hard woods a head start toward seasoning with age, and helps pull water out of the lignins and hemicellulose, which is kind of what 15+ year seasoned old wood is like. It's all stoopid stuff I can sell, or use. I get $2000 for a Crookes tube with a copper lightning bug coated in phosphorescent paints, that glows when someone keys in Morse code broadcasting CW. I use the wood in repairing guitars. I may start to charge more for the tubes. I am in America, but after college & work one gets used to converting from imperial to metric and back again.
im really quite impressed that you did most of the talking about the experiment in one take lol i was watching the clock waiting for a cut. Love your videos
Open the gas ballast a tiny bit on your pump while there is moisture in the chamber. That helps sweep away moisture from the pump oil. Pump oil will eventually need changed once you notice it getting frothy or if you have a micron gauge you can see that it doesn't pull as low
your boiling water subjects your ramen to 212 F (or 100 C) for a period of time (the temperature is what cooks the ramen). the boiling happening in the video is clearly happening at 60 F (or 15 C) (and actually gets colder until it freezes) and while initially, this would soak the ramen, it would not "cook" it in the sense that you are describing it.
i beg to pick. as ramen isnt food, cooking does not apply. culinarily, soak your ramen without boiling and tell me if they are done.. yep. they are. maybe some actual heat would suggest a more palatable starch, but lipstick on a pig. although I suspect the freeze dried onion wouldn't reconstitute well. as well, some of the finer rice noodles cant stand true cooking. just soaking. so then, will the hydration balance into a dry starch stick under vacuum? lastly, how's the gravity pump coming?
Sure, if your blood was also in a cup like this it would boil, but since its usually contained in your body that provides some positive pressure it wouldn't boil.
Han Solo blood will boil and form bubbles of oxygen in your arteries, so it doesn't reach the capillaries anymore. Also, the fact that your body is two thirds water and you can see what happens to water in a vacuum kinda shows what would happen to you
Exactly what i thought..Very less mass to measure and also nothing to cool it down. Yeah, i'm wondering and searched for someone who als was wondering :P
It reads the temperature from inside the ice at the tip of the thermometer rod, not the air surrounding the rod. The thermometer cools down because there are two types of water in that beaker: somewhat hot water molecules and somewhat not hot water molecules. Temperature is just the average of all of the water molecules' energy or vibration speed, ie heat, not the heat of every molecule present. Because the air pressure is dropping, there is less air pushing down on the water to keep everything in the liquid phase, and so the somewhat hot water molecules take heat/energy from the somewhat not hot molecules changing the molecules present to either hot and not hot water molecules. The hot water molecules have enough energy to evaporate, so they do, and the not hot water molecules are cold enough to freeze, so they do. The only mass left for the thermometer to measure is the ice that surrounds the probe point, which is at 0 degrees Celsius.
Amazing. At my job, we have big propane tanks that we draw a lot from each day, and this same process will freeze them on a decently cool day. We have to put steam jackets around to keep the vapor pressure up.
Number 2. 1- Place two electrostatic charge generators (electric cable, glass marble, aluminum foil) inside the water glass. 2 - Then place the glass inside a magnetic field (ferrous magnets although electromagnets are stronger). 3 - Finally add two ultra-frequency transmitters. 4- Activate the whole and observe what happens.
I have used water in an insulated test tube to confirm vacuum levels while working on large industrial and petrochemical refrigeration systems. Our test tube was external to the system and connected by copper tube. It is a very reliable way of measuring the vacuum while also ensures there is no moisture in the system.
That is neat! Congratulations, you deserve it. I really enjoy your fun, informative videos. You do such a good job of describing what's going on and explaining the science that I don't skip to the end to see the results like most videos.
the temp from vacuum chamber is irrelevant if is vacuum, if you put two thermometer for example, one at room temp and one from 40 degree, they both indicate diferite inside of a vacuum chamber
Hi Cody can you disprove the flat earth theory! the more i look the more i get confused,so many unanswered questions.Things like god light in which the sun would have to be much closer? No flights over the south pole? Able to see great distanceses in a stright line without seeing the curvature ? So many. I watched in one of your vids,where you want to be on a mars mission, so i hope you wont frown to much over my question. On a lighter subject, ever done any cuttlefish casting,easy and fun. Would also like to here what are your thoughts on Nassim Haramein theory
light is effected by gravity. so some of it bends [a little bit] around the curvature of earth, so things that are behind the curve of earth that you wouldn't expect to be able to see. its not enough curve to be able to see the opposite side of earth, obviously, but its an almost minuscule curve that gives us a slightly longer view. i'm pretty sure this is easily testable in the ocean. the earth is much bigger than we can imagine. the horizon that we see is merely a pore of earth
Im a simple European, i see an American uses the metric system, I press like.
Techies most people use metric in science
Sadly not enough on youtube, i mostly see americans only use the imperial, which is no problem, but if they dont even "translate" it to the metric it is kind of insulting.
Techies We wouldn't want to insult the great and merciful leader Techies now would we?
Techies I've been on an American farm/ranch all my life and every day I find myself fantasizing about the metric measurement system =/
Americans don't use the imperial system. They use the English system which is not the same as the imperial system used in England before it went mostly metric.
Freezer manufacturers hate him! Find out how this man makes ice cubes in just 20 minutes with one simple trick!
Freezer ice machines can make ice in a few seconds
It only takes about 5 minutes to get the water real cold
yayo bro pretty sure it’s prefrozen and just gives out the frozen ice🤔
@Squad 47 jesus why so toxic. ice dispensers obviously dont make ice right on time whe you press the button to give out the ice. its already frozen and stored then. then other ice is made to refill the storage room
And he hates liquid nitrogen, which freezes water even faster
I have seen this on graphs, and i just kind of took it for granted, but seeing it actually happen with my eyes is something completely different. A deeper understanding. Thanks for the video and your effort.
found the comment i was looking for
literally just had this in Uni today lol (also with the graph)
I love that you drank the water to show it was ordinary...we've watched you drink cyanide water Cody, you drinking it proves nothing normal lol.
He dips his hands in mercury, acid... this colorless liquid could be anything of it's cody who's drinking it.
He's quite obviously a Terminator cybernetic infiltration unit, series T-800.
This would also explain his surgical implementation of a magnet as a replacement for a burned out wrist servo.
Merp I was thinking the exact same thing
manictiger He's def a skynet model. T-800 I couldn't tell ya...but his cpu is obviously a neuronet processor, a learning computer.
Merp Ikr that's what I was thinking "why are you drinking it to prove something, bro? I'm sure you've drunk way worse things nonchalantly..."
Respect for using celcius. Glad that some youtuber understand that statistically more of their viewers use the metric system, rather than the nonsense crazy system.
It's also the correct scientific system....
muddy watters show me that statistic
Fahrenheit might have been arbitrary, but it wasn't nonsense at the time. We cope with both just fine, thank you.

Cody: See this is normal tap water.
Cody: Drinks from glass.
Me: oh that’s unusual, normal water?
Cody: haha just kidding it’s mercury.
Hahaha right? Cody has literally ingested so many things on this channel that him drinking something is 0% proof that that thing is water 😂
cant trust cody could of been cyanide
now freeze water till it boils!
lol wat :D
if this were pure water, you would've been able to see the frozen ice turn back into liquid at 0.01C and 6mm of Mercury but it was tap water so it had many ppm's of salts
Stony Tark all you need to add is hydrogen oxide as it boiling the water will too
Does bringing it to the triple point also count?
Stony Tark
Sorry if drinking it didn't convince me it was tap water after you drank cyanide ;P
That is the first thing I thought. HAHA! :)
I loved the small annotation he popped up saying "This proves nothing" XD
TheGinginator14 I was going to comment that too haha
I literally commented that then saw this xD, my bad mate😬
Thats what i thought when i saw that

yeah, made me literally lol - quite rare reaction from me, recently.
But the question is : DO POPSICLES TASTE BETTER WHEN DONE THAT WAY ?
Also is it faster to make 'em that way ?
these are the REAL questions we need answers to
Also is it electrically cheaper to make them with a vacuum?
From the video i'd say it's a lot quicker because he had the whole thing converted to ice after 12 minutes, whereas it would have taken probably more than 1/2h in the freezer.
ah, but it'd probably cost more as a lot of the liquid would boil away before it freezes
"Let me change that to celsius so that you guys don't give me grief" lmao
Some kids at my school don't believe me when I say water can boil at low pressure, then get cold. They called me stupid.
show this video to them

No point by drinking the water on video for us to make sure it is legit, since you already eat and drink all kinds of crazy chemical stuff hahah
Am I wrong haha?
Good point... ;)
Kottethebest_ClashOfClans That was my first thought when he drank that. :p
Cody'sLab hes got a valid point
but idk y
for some reason i half expected you to drink the water and get iocaine poisoning or something.
if you get reference leave a like
It's either tap water, mercury, or cyanide. Got it!
This is the best video I've seen showing this process. Most people do nothing to negate the violent boiling and end up showing nothing useful.
I can see you making elemental fluorine from toothpaste or something, and actually managing to store it for the long term
"so you see, it's starting to casually burn anything inside here.. Wait" :D
+Muzik Bike - Geometry Dash and stuff
Cody - the only person crazy enough to just carry cans of Fluorine gas around in his pockets :P
Evan Blenkinsopp Almost sounds like a weapon a mad scientist zombie or something would use
Cody is the man you wanna be with when zombie apocalypse happens
As much as Cody likes to do dangerous things, I don't think he would mess with fluorine.
5:54 "How cool is that"
"0 degrees C"
I love you, Cody.
The freezing phenomenon is quite common and is easily anticipated. The overarching relationship is the vapor pressure curve. If at a certain temperature and pressure, liquid water should be a vapor, the liquid will suck energy out of the water to vaporize. The huge latent heat of water causes the water temperature to drop. But the vacuum continues to go down so the steady suckage of energy continues until the water is frozen. Then sublimation takes over.
Most liquids exhibit this phenomenon. But water has the highest latent heat of vaporization so the effect is more dramatic.
I am most glad that this experiment does not involve mercury. One day you may get madder than a hatter.
The barometer had mercury in it.
um what
titaniumsandwedge is this from wikipedia?
This is a well known thermodynamic principle and is probably on wikipedia.
Your explanation is not wrong, but you some funny language that convolutes the thermodynamics a bit. Maybe I can restate your point so they understand.
The process of water boiling is exothermic, it requires water molecules with enough kinetic energy to leave the bulk water and surface tension layer. Since temperature is just the average kinetic energy of water molecules, the fastest moving molecules will boil first, leaving the remaining water with a net loss of kinetic energy so that it's average temperature is now low enough to freeze.
0:36 is funny as hell because you drank cyanide not long ago.
Still, I think we all just believe you when you say something.
Hey, that cyanide solution was mostly water too!
Frederik Claeyssens wait, he did? Shouldn’t he be dead now? What was the vid title of him drinking it?
Yasin Omidi the amount makes the poisons and the medicines. Many poisons are used in lower amounts as medicine eg curare in surgery. Hell many fruits have cyanide or cyanide like compounds so all of us have eaten cyanide most likely at some point
+Eagle 367 Pretty sure you're thinking of the fruit pits (apple seeds, peach pits, etc.). Also the phrase is "the dose makes the poison," I think you just quoted a song right there ("The Difference Between Poison and Medicine is the Dose" google it). But otherwise you're right.
Plus, not all cyanide compounds are dangerous. Cyanocobalamine is a cyanide compound, and it's better known as vitamin b12. (This is why hydroxycobalamine is used as an antidote in France; it binds with the cyanide group in, say, hydrogen cyanide, and forms b12 instead). Prussian Blue is still commonly used as a blue pigment (that's why it's called Prussian *Blue*, not Prussian Pink or something) and (as Cody mentioned in a different video) is used as an antidote to thallium.
Citation: Molecules of Murder by John Emsley. And wikipedia.
Also, I can't find the cyanide video that everyone keeps talking about. I want to watch it, but not nearly as much as I want to explore the comments section because I'm sure it will be an interesting one.
I'm expecting Cody in one of the next videos to say "this is some ordinary tap mercury" while he sips a bit of it.
Wow that was way cooler than I expected. I knew a lesser atmospheric pressure would cause water to boil at a lower temperature, I had no idea how far you could push it though! Awesome job.
This was intriguing... and your watch was at 11:11
The water was boiled for safety. Wait... wrong channel...
re8nifle 😂
well, given the fact both boiling and freezing tends to make cell membranes rupture, this _might_ sterilize it... maybe...
The power of irony is what brought me here. Really happy that it did so, though.
My favorite science teacher by far
I really appreciate you using metric measurements, Thannks Cody!!
He says "this is some ordinary tap water" then he takes a sip of it, and I'm thinking "okay, that's cyanide there, not tap water"
:S
We used to do something similar to this, though it never froze for us. We used to seal water inside a glass jar and turn upside down. Then we would put ice on the top, this would cause a drop in pressure and the water to boil. Just an odd thing we used to do.
i must try this..
Nicholi Martin the ice cube made the air shrink enough for the dissolved oxygen In the water to come out and regulate the pressure but in this the air came out to regulate the pressure and got sucked out making there no barrier I guess and the water froze
It did pull the oxygen out, but if you have enough room in the jar with enough water you can still get it to boil, just not freeze. I just thought I would mention something fun I did years ago for my nieces.
Hey I don't understand why the drop In pressure in the video caused the water to freeze. With looser bonds, the molecules should be more active and be able to boil more. So why did the drop in pressure cause the water to freeze? It's been about 6 years since I last took chemistry
The boiling point just means the energy it takes to go from the liquid phase to the gas phase. Since the more energetic molecules are going into the gas phase, the remaining are of a lower temperature. That is basically why.
What would happen to the water in a very high pressure chamber, the opposite of vacuum? Does it just become vapor?
nope, just higher density water, though it would absorb more oxygen.
upload.wikimedia.org/wikipedia/commons/thumb/0/08/Phase_diagram_of_water.svg/700px-Phase_diagram_of_water.svg.png
I heard of a planet that was discovered (the Thoughty2 video about 10 strange planets), that mostly consists of water and in a depth of X km under the surface the pressure forces the water to become ice, while the temperature is around 600°C or so. The ice is called ice X (ten) and is probably as hard as rock (sry if these information are not accurate it's a while since I watched it)
So could you make some breathing aparatus with air from lungs filtered through this high pressure water (That has been enriched with oxygen ) ? Just like Acetylene = Acetone + Ethyne < I think :) Sorry for bad english
it will eventually freeze solid, but only at pressures above 1 Gpa (10k Bar)
This was pretty interesting! I don't know why it never occurred to me that water would behave this way. I would have assumed that the water would just boil off until it was gone. It works just like the refrigerant in an air-conditioner or fridge. Only instead of compressing a gas to make liquid, you're depressurizing a liquid so it gases off... AND FREEZES. Fascinating!
Isn't a perfect vacuum only theoretically possible? Even in very deep space you will still have a certain number of Hydrogen atoms within a meter cubed.
Camroc37 yes
That depends, in a small enough volume you can't *fit* an atom, the lower the pressure the less likely any given volume is to contain anything at all. In the lab it's possible to make milliliter perfect vacuums easily enough.
Mostly you just classify the kind of vacuum by the pressure left (normal, high, ulta high, etc.). So in a classical setup you will mostly just say it has a strong vacuum with 10^-9 bar or so. But if you try to push the limits with like very small volumes, you might crack the usefulness of the difinition of vacuum. Even if you manage to get out all gas and other real particles, you end up with vacuum fluctuations and thus virtual particles (quantum mechanics) which are basically pairs of matter and anti-matter popping in and out of existence. Those are always there and also can do work (see casimir effect), even though you classically (newton mechanics, thermodynamics) have a perfect vacuum. So if you try to be precise you have to check definitions and their purpose. I hope that helped^^
Does it matter, though? This experiment hardly needs a _perfect_ vacuum.
Camroc37 although you are right we have no way to make a true vacuum
''Just ordinary water!'' •Drinks•
*One week ago*
"See, I can drink this cyanide solution and be perfectly fine!" •Drinks cyanide•
first video I've watched of yours. I'm instantly enthralled
you know just because you drink it doesn't mean it's tap water especially with you cody
Hi Cody, In a previous video you mentioned that mercury has a vapor pressure as well, since it too is a liquid, although much lower than water. Would you be able to boil liquid mercury in a similar setup to this one? And eventually get to solid mercury?
For that I would really have to put it in space since the vapor pressure at the triple point is something like 10^-12 torr. But yes it would be possible.
this has been done with liquid nitrogen, nothing special, just like gallium when a bit cold
Hey Cody, really love your videos, hi from Australia!
@kurpingspace productions
I think the point of what he was asking was not whether or not mercury could be frozen, but whether or not it could be frozen via the same method as in this video, by way of decreasing the atmospheric pressure around the mercury.
I was actually thinking of checking out this channel recently. Stumbled apon this video looking for something else and didnt realize it was codys lab until the vid started. What a pleasant surprize. Ive been watchin since back in 2010ish when there were only like 50k subs. Nice to see this channel blew up. Good for you cody hope your doing well!
I love how he drinks it to prove it's tap water. As if we haven't seen him drink cyanide already!
I've had this water / pressure question since I took physics in high school. If you had a pressure chamber capable of increasing the pressure inside above 784 times that of atmospheric pressure would there be a point where water becomes buoyant due to it's inability to compress significantly and it's density would be less than that of the surrounding air?!
This really made me wonder, In theory I think you would be able to, It would just be a challenge to make such a high pressure chamber along with some unexpected side effect that I'm sure would pop up. It would definitely look interesting though.
I asked my physics teacher that question in High School and he was stumped. In theory it makes good sense, but has anyone ever done it?
Substances have a critical pressure and temperature, which after that T and P are reached, the substance will be a supercritical fluid and exhibit properties of both liquid and gas. 784 atm is well past water/airs critical P/T so at that point, you would simply have a one phase mixture of water and air combined. Feel free to read more on the phenomenon en.wikipedia.org/wiki/Supercritical_fluid. And there are also some cool youtube videos showing the effect.
No evidence or research here, just a question, but would not nitrogen and oxygen condense or even sublimate at that pressure?
Massive Black hole would open up and swallow the earth! True Story, I've done it before!
You could put a fine mesh wire fliter over the cup with the water in the chamber to avoid the small droplets from slushing out and covering the glass. The vacuum should still make it through just fine. Great experiment!
I love how you drink the water to prove that it is normal water, when we have seen you drink many abnormal things
"how cool is that? 0 degree C" lol
I know this is an old video but nice nonetheless. I used to work at a well known pharmaceutical factory. We made a vaccine called Yellow Fever, the process, without getting into too much detail, used a process called Lymphinizing. Basically freeze-drying the vaccine into a dry cake. They used a reconstitution method using sodium chloride to make it into an injectable. Really cool process to be seen first hand and educating. Thanks for the video Cody, learned a lot from working at that place.
Funny how he drinks to water to prove it's water but we know he'll drink weak cyanide solution.
I liked that annotation when you took a sip of water.
he tries to prove something, which is nothing tho.
The first AC systems were on railroad passenger cars. They used a steam powered aspirator to pull a vacuum in a chamber of water. The chilled water was pumped to cooling coils in the passenger compartment.
how would a mechanical clock be affected by the vacuum? i could imagine it running faster
(at least if its not hermetically sealed)
a quarts watch should have no change, not sure on mechanical though, my guess is it would speed up slightly for the reasons you mentioned.
If the watch ran faster in a vacuum, then the seals and gaskets would have failed. If the gaskets did fail in a vacuum, then the watch crystal would literally blow off. This is sometimes observed by deep-sea divers. All watches that have been used in EVA's have survived (to my best knowledge and research). Which means that their gaskets didn't leak any internal pressure.
Electronic wach precision is governed by a quartz crystal inside. Those crystal are sealed in a small metal can since the crystal naked is very fragile. wach Crystal is called tunning fork crystal. It resonates at an exact frequency (like a diapason). Wach chip divides this reference to get seconds, minutes and hours. So, even when its true that there is sort of mechanical part inside an electronic wach, it is super sealed. The facts that make crystal drift are TEMPERATURE (heavy quadratic dependence) and vibrations (can even damage the Crystal). Also, the wach chip is not very tolerant when some properties of the Crystal change, so even when it coul drift tooo much, it will make the wach fail completely. Chip is also super sealed also. Like other user said, the LCD screen could be damaged but doubt the wach could get damaged. Almost every electronic gear around us use quartz crystals as time reference. Crystal are cut to a specific frequency. Ok, not very interesting ....but wach Crystal is working at 32768Hz (oscillates 32768 tmes per second). It a CLASSIC number for sure. Timekeeping in the computers use the same. Crystals eventually age and drift permantly every year (wach can get slower or faster ... just by a very small amount, like 5ppm). Computers have no probs since they go and adjust the time using time servers over internet. So do the phones. HIGH precision references for laboratory use CESIUM. Those ones are insane accurate and wont drift. Precision time could be derived from them
38911bytefree Not sure if this is also directed towards me. But to clarify I was only talking about mechanical watches, not quartz or tuning forks. Also my mention of "crystals" was in reference to the case crystal, the front glass of the watch in which you can see the moving hands, not the quartz crystals.
Dylan Greene Was general info kind of post, I am writting (I think it is still possible) my opinion on what I think is happening or not happening. Didnt read you mention about crystals, just read the firs and second comment I believe (didnt click see more). So, no worries.
"How cool is that?"
[0°C]
"You can see it's freezing. That's pretty cool."
Master of understatement.
Just so you know, high vacuum is classified as pressures from 10^-7 torr on, or a millionth of atmospheric pressure. You achieved middle vacuum, barely, impressive with only a mechanical pump. You would need a diffusion pump to get lower.
That pressure gauge is hideously inaccurate for the kind of work you do.
Actually 10^-7 torr or less would be considered Ultra High Vacuum. And to get to those levels not only a turbo or diff pump will be enough, but better seals and a clean chamber would be nice. :)
Anyone know what kind of force would be acting on that (perspex?) door? It looked quite thin and had a large surface area so when he was talking about a 'high vacuum' it seamed a little concerning.
Then again it didn't appear to flex in and become concave or anything so it must have been all good. Is that some kind of crazy strong door or was the force a lot less than i'm imagining?
J Paino never more than 1 atm of pressure.
+J Paino
That door seems to be about 1 foot in diameter. That's about 113 in^2 of surface area. And 1 atm of pressure equals to about 14.7 PSI.
So, multiply both and we have about 1662 pounds of force.
But it's not a complete vacuum so it's gonna be less than that.
Hey Cody i have a question i dont now if you could manage to do this but im wondering if you could pop popcorn in a vakum im wondering if it would be fluffy like it is or not or would it be even bigger ? si when it is not too hard for you to creat the heat or microwaves in the vakumchamber (since its a vakum i think we can left the microwaves a side) too pop the corn that would be totally awesome.
Greatings from Germany keep doing your great Videos !
I can pop corn with my laser! Yep, Ima guna go do this right now.
Cody'sLab film it
***** you are awesome ! I was wondering still a time what would happen is the air in the popcorn intermolekular so is it producing wenn it pops or is the air from the outside and what happens in the vakum it will be so interresting ! :))
I picked up a large old Robinair vac pump ages ago, with an absolute pressure gauge, but I need to pull more vacuum, for making Crookes, and Geissler tubes. I have a reliable source of cheap (free) helium, neon, krypton, argon, nitrogen and other gases. I am also running a solar torrefication chamber for baking wood in the absence of oxygen. The process mimics or at least gives hard woods a head start toward seasoning with age, and helps pull water out of the lignins and hemicellulose, which is kind of what 15+ year seasoned old wood is like. It's all stoopid stuff I can sell, or use. I get $2000 for a Crookes tube with a copper lightning bug coated in phosphorescent paints, that glows when someone keys in Morse code broadcasting CW. I use the wood in repairing guitars. I may start to charge more for the tubes. I am in America, but after college & work one gets used to converting from imperial to metric and back again.
"Is never gonna freeze cuz is boil"
Water ice salt aye
Hey Cody. Last week Veritasium made a video about cold welding. Do you think it would be possible to show that using your vacuum chamber?
yes, moving things in there will take some work though.
I'm curious as to what ideas you have.
I don't really know at all what your talking about sometimes but your videos for some reason they are really entertaining. Keep it up
Could a vacuum chamber be used to cool beverages down quicker than a normal freezer would? How do carbonated drinks behave in a vacuum?
They explode!
That wasn't normal water, there is cyanide in it. Cody puts a little in all the water he drinks.
You know I actually used to do that for high altitude training.
That must have been a small amount then, and even if it is, wouldn't that have long-term effects?
Cody'sLab wtf
Seph Bane huh?
gotta build up that resistance lol
im really quite impressed that you did most of the talking about the experiment in one take lol i was watching the clock waiting for a cut. Love your videos
I own the same watch and I'm curious whether its pressure gauge would have stayed accurate ...
not at all. it seems to conk out at just 30,000ft
Ahah amazing ! Thank you :D
What brand/model is it? I was just thinking about that.
That's a Casio SGW300H with pressure and temperature gauge :)
Aumetre Antonin Thanks!
I love learning from you, Cody! :D
Open the gas ballast a tiny bit on your pump while there is moisture in the chamber. That helps sweep away moisture from the pump oil. Pump oil will eventually need changed once you notice it getting frothy or if you have a micron gauge you can see that it doesn't pull as low
So if I cooked my ramen noodles in boiling water in a vacuum chamber, would my noodles be cooked? :D
no
Oh... Well thanks for the response!
your boiling water subjects your ramen to 212 F (or 100 C) for a period of time (the temperature is what cooks the ramen). the boiling happening in the video is clearly happening at 60 F (or 15 C) (and actually gets colder until it freezes) and while initially, this would soak the ramen, it would not "cook" it in the sense that you are describing it.
i beg to pick. as ramen isnt food, cooking does not apply. culinarily, soak your ramen without boiling and tell me if they are done.. yep. they are. maybe some actual heat would suggest a more palatable starch, but lipstick on a pig. although I suspect the freeze dried onion wouldn't reconstitute well. as well, some of the finer rice noodles cant stand true cooking. just soaking. so then, will the hydration balance into a dry starch stick under vacuum? lastly, how's the gravity pump coming?
it will freez
would this same principle cause your blood to boil in space
yep
Han Solo Your blood starta boiling before you leave the atmosphere
Sure, if your blood was also in a cup like this it would boil, but since its usually contained in your body that provides some positive pressure it wouldn't boil.
well this comment chain was a bit... morbid
Han Solo blood will boil and form bubbles of oxygen in your arteries, so it doesn't reach the capillaries anymore. Also, the fact that your body is two thirds water and you can see what happens to water in a vacuum kinda shows what would happen to you
i love the way you sciences the hell out of everything. if we had teachers like you we would have more engineers.
Cody, you have to understand that you taking a sip of a clear liquid does not prove it being safe at this point... xD
with this little air in the chamber, is the thermometer even able to give you the surrounding temperature? Where is it taking the reading from?
Exactly what i thought..Very less mass to measure and also nothing to cool it down. Yeah, i'm wondering and searched for someone who als was wondering :P
If the Thermometer doesn't Cool down, how should the water Cool down?
It reads the temperature from inside the ice at the tip of the thermometer rod, not the air surrounding the rod. The thermometer cools down because there are two types of water in that beaker: somewhat hot water molecules and somewhat not hot water molecules. Temperature is just the average of all of the water molecules' energy or vibration speed, ie heat, not the heat of every molecule present. Because the air pressure is dropping, there is less air pushing down on the water to keep everything in the liquid phase, and so the somewhat hot water molecules take heat/energy from the somewhat not hot molecules changing the molecules present to either hot and not hot water molecules. The hot water molecules have enough energy to evaporate, so they do, and the not hot water molecules are cold enough to freeze, so they do. The only mass left for the thermometer to measure is the ice that surrounds the probe point, which is at 0 degrees Celsius.
I had no idea there was a higher vacuum than what exists in space. Or rather, that it held different properties than "regular vacuum". bravo!
I haven't watched oyu in a while, and seeing cobalt in the intro makes me hyped.
Lazy thermometer only works under pressure! :P
Cody, just because you drank it doesn't mean it was 'ordinary water'. We know you too well for that (and your awesome btw).
Cody, drinking out of a glass to prove it's "water" is hardly a reliable proof in your case. You drink cyanide. _Edit: Heh. Just saw the annotation!_
Does the boiling water favor lighter hydrogen atoms
yes, yes it would.
protip: watch his heavy water videos
Cody'sLab STOP GOLD DIGING .....
Amazing. At my job, we have big propane tanks that we draw a lot from each day, and this same process will freeze them on a decently cool day. We have to put steam jackets around to keep the vapor pressure up.
"How cool is that?" 0° 😂
In Soviet Russia, water boils frozen!
Number 2.
1- Place two electrostatic charge generators (electric cable, glass marble, aluminum foil) inside the water glass.
2 - Then place the glass inside a magnetic field (ferrous magnets although electromagnets are stronger).
3 - Finally add two ultra-frequency transmitters.
4- Activate the whole and observe what happens.
Alright, it's actually freezing, how cool is that? *caption* 0*C. Lol,
Celcius much appreciated!
I have used water in an insulated test tube to confirm vacuum levels while working on large industrial and petrochemical refrigeration systems. Our test tube was external to the system and connected by copper tube. It is a very reliable way of measuring the vacuum while also ensures there is no moisture in the system.
Next Video: *Freezing Water Until it Boils*
What would happen to salt water?
Thomas Daniel impurities lower melting/freezing point,raises boiling point.But there are more parameters such a vapour pressure
"ordinary water" probably was acctually the radioative one.
hey man, congrats on the popular mechanics article for your video!

That is neat! Congratulations, you deserve it. I really enjoy your fun, informative videos. You do such a good job of describing what's going on and explaining the science that I don't skip to the end to see the results like most videos.
WATER NEVER GONE FREEZE CUS ITS BOILT ITS BOILT IZ BOILT
Video Epic Reviews LMAO
A WATER BALLOON?
Nina Jur YOU JUST READ MY MIND
yup classic thermodynamic experiment. By decreasing pressure you pass the triple point of water and it freezes at less pressure. good explanations :)
I wanna video on that vacuum gauge. Right away
Albion Laster it is called a barometer
Alex Nigrine
no its not. barometers measure atmospheric pressure. vacuum gauges measure the pressure below atmospheric.
Albion Laster thanks
Specifically known as a manometer
it still works as a barometer though
0:30 you sure that's not your cyanide water?
*takes drink*
"The water is actually freezing. How cool is that?" and then a 0 degree pops up for a split second. That's the puns i like :D
the temp from vacuum chamber is irrelevant if is vacuum, if you put two thermometer for example, one at room temp and one from 40 degree, they both indicate diferite inside of a vacuum chamber
Hi Cody can you disprove the flat earth theory! the more i look the more i get confused,so many unanswered questions.Things like god light in which the sun would have to be much closer? No flights over the south pole? Able to see great distanceses in a stright line without seeing the curvature ? So many. I watched in one of your vids,where you want to be on a mars mission, so i hope you wont frown to much over my question. On a lighter subject, ever done any cuttlefish casting,easy and fun. Would also like to here what are your thoughts on Nassim Haramein
theory
Have you seen this video?: th-cam.com/video/B5maJBnv37E/w-d-xo.html
light is effected by gravity. so some of it bends [a little bit] around the curvature of earth, so things that are behind the curve of earth that you wouldn't expect to be able to see. its not enough curve to be able to see the opposite side of earth, obviously, but its an almost minuscule curve that gives us a slightly longer view. i'm pretty sure this is easily testable in the ocean. the earth is much bigger than we can imagine. the horizon that we see is merely a pore of earth
It's not because of gravity. It's atmospheric lensing.
NERD ALERT!
NERD ALERT
You could do this using a syringe. Not sure if it will boil until it freezes, but it will definitely boil at room temperature.
Cody can you do the Mercury bottle flip
