Im a simple European, i see an American uses the metric system, I press like.

[@rookas6274]

Techies most people use metric in science

[@MechanicalDoll]

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.

[@krispyasfuk9622]

Techies We wouldn't want to insult the great and merciful leader Techies now would we?

[@Ybw200owns]

Techies I've been on an American farm/ranch all my life and every day I find myself fantasizing about the metric measurement system =/

[@thomasyates3078]

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!

[@yayobro7194]

Freezer ice machines can make ice in a few seconds

[@suabroboro]

It only takes about 5 minutes to get the water real cold

[@ShiNiGaMi-bb2ep]

yayo bro pretty sure it’s prefrozen and just gives out the frozen ice🤔

[@ShiNiGaMi-bb2ep]

@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

[@yingxiawei821]

And he hates liquid nitrogen, which freezes water even faster

[@carrotylemons1190]

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.

[@JB-fh1bb]

Hahaha right? Cody has literally ingested so many things on this channel that him drinking something is 0% proof that that thing is water 😂

[@Capricorn_media_group]

cant trust cody could of been cyanide

I saw that and was instantly dissapointed in Cody.

[@FilterYT]

Ha, love that too!

[@StolenPw]

ALEX WHERE DID YOU FIND THAT ICON

[@MerpSquirrel]

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.

[@toucaninterieur8011]

He dips his hands in mercury, acid... this colorless liquid could be anything of it's cody who's drinking it.

[@manictiger]

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.

[@millascreations3289]

Merp I was thinking the exact same thing

[@landofthebees]

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.

[@whatif3271]

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..."

[@cile12345]

now freeze water till it boils!

[@ReDMooNTVV]

lol wat :D

[@icedeskimo4432]

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

[@AesopFable]

Stony Tark all you need to add is hydrogen oxide as it boiling the water will too

[@Celrador]

Does bringing it to the triple point also count?

[@conor9209]

Stony Tark

[@Inertia888]

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.

[@gBaldaconi]

found the comment i was looking for

[@natfailsyoutube8163]

Might've just been added, but "this proves nothing" appears onscreen via an annotation when he drinks it ;)

[@ozzy10440]

ryanburbridge right! was thinking the same thing! #notreallytapwater

[@omergezer6368]

i thought the exact same thing

[@theduder2617]

Excellent inquiry! But be aware, I SUCK as a teacher. And what I leave here as a response, I advise anyone curious to check on it. If I am wrong, I will acknowledge my error and make efforts to correct the error(s). Since the chamber is already at it's maximum vacuum (or at least close), turning off the pump will cause the boiling action to slow down with time. Assuming the chamber has no leaks, the water will continue to boil and cool until the escaping water molecules equalize the vacuum in the chamber. The vacuum will not equalize completely. But enough to slow and eventually stop the reaction, and eventually the water remaining will return to the ambient temperature of the chamber. But his moisture absorbing powders inside might end up absorbing all of the water in the glass if left in the chamber for a time period. The pump must remain running in order to maintain the vacuum needed for this experiment to do what it is doing. Remember, that water is not just boiling. It is also "evaporating", or achieving vaporization as it boils. The same as on your stove top. And is why he added the moisture protection to his chamber. The water molecules will attack the piston wall of the pump, lowering it's ability to pump air, if it does not do more damage that is. (The only reason for the temperature drop in this experiment is due to the fact that the water is evaporating, or "vaporization" to be technical. It's the same idea behind the fact that sweating aids in cooling our body. Without the vaporization, temperature will not lower without external forces. (air conditioning, freezers). And when the vacuum stops, so will the vaporization process. Usually takes a full 3-5 minutes depending on the power of your vacuum chamber for the process to slow to a stop. (+/- several minutes) ALL THE ABOVE BASED ON USING ONLY WATER IN THE GLASS WITHOUT ANY ADDITIVES SUCH AS IN THIS VIDEO

[@muddywatters4886]

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.

[@garrettmillard525]

It's also the correct scientific system....

[@KnowledgePerformance7]

[@JohnMichaelson]

Fahrenheit might have been arbitrary, but it wasn't nonsense at the time. We cope with both just fine, thank you.

[@muddywatters4886]

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.

[@Nightenstaff]

It's either tap water, mercury, or cyanide. Got it!

[@Steve211Ucdhihifvshi]

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

[@oldbloke135]

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.

[@toucaninterieur8011]

But the question is : DO POPSICLES TASTE BETTER WHEN DONE THAT WAY ?

[@toucaninterieur8011]

Also is it faster to make 'em that way ?

[@MasterGXD]

these are the REAL questions we need answers to

[@lightdark00]

Also is it electrically cheaper to make them with a vacuum?

[@toucaninterieur8011]

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.

[@Glant418]

ah, but it'd probably cost more as a lot of the liquid would boil away before it freezes

[@scorpianguitar]

What would happen to the water in a very high pressure chamber, the opposite of vacuum? Does it just become vapor?

[@theCodyReeder]

nope, just higher density water, though it would absorb more oxygen.

[@estoniaman]

[@Magalter]

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)

[@unity4alle1]

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

[@TheKnaeckebrot]

it will eventually freeze solid, but only at pressures above 1 Gpa (10k Bar)

[@zrodmg6449]

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.

[@yasinomidi7525]

Frederik Claeyssens wait, he did? Shouldn’t he be dead now? What was the vid title of him drinking it?

[@eagle3676]

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

[@jennali9800]

+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.

[@titaniumsandwedge]

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.

[@theCodyReeder]

The barometer had mercury in it.

[@marlingod]

um what

[@theend3244]

titaniumsandwedge is this from wikipedia?

[@titaniumsandwedge]

This is a well known thermodynamic principle and is probably on wikipedia.

[@taylorwestmore4664]

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.

[@jarrod0987]

Dude!! This is one of the coolest Science demo's I have ever seen :D Thank You.

[@Camroc37]

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.

[@bradleywangyang1071]

Camroc37 yes

[@garethdean6382]

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.

[@hanswoast7]

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^^

[@Nyerguds]

Does it matter, though? This experiment hardly needs a _perfect_ vacuum.

[@emmitunderwood9502]

Camroc37 although you are right we have no way to make a true vacuum

[@Stevebroza]

I really appreciate you using metric measurements, Thannks Cody!!

[@fleshtonegolem]

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?!

[@nitrodasnipaz9392]

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.

[@fleshtonegolem]

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?

[@tinymarshable]

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.

[@RCassinello]

No evidence or research here, just a question, but would not nitrogen and oxygen condense or even sublimate at that pressure?

[@blameusa7082]

Massive Black hole would open up and swallow the earth! True Story, I've done it before!

[@Smirkku]

Your channel is really awesome, keep it up Cody! :)

[@michaelbeal207]

I love how he drinks it to prove it's tap water. As if we haven't seen him drink cyanide already!

[@nicholi8933]

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.

[@Eng.Creation]

i must try this..

[@pyrothedude4243]

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

[@nicholi8933]

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.

[@jason200912]

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

[@nicholi8933]

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.

[@tracylemme1375]

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.

[@HARBINGER8752]

holy crap this is so cool!! I've wondered if this was possible before (I used to get REALLY bored at school) and I'm glad to see someone else with the tools and knowledge to do this wondered the same thing.

[@VictorJacek]

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?

[@theCodyReeder]

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.

[@kai_unix]

this has been done with liquid nitrogen, nothing special, just like gallium when a bit cold

[@joeyfathom]

Hey Cody, really love your videos, hi from Australia!

[@fuegoisfire1]

@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.

[@roryos]

I love learning from you, Cody! :D

[@fatshadow2062]

"You can see it's freezing. That's pretty cool." Master of understatement.

[@slimjim5199]

you know just because you drink it doesn't mean it's tap water especially with you cody

[@spacerag]

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!

I have used water in an insulated test tube to confirm vacuum levels while working on large industrial and petrochemical refrigeration systems.

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.

[@benmunday5531]

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?

[@1389ultrasrbin]

it will freez

[@drainbb]

cody would be an AMAZING science teacher!

[@ennerbuddy2956]

Just when I thought the recommended box couldn't get any stupider, you go and give me something like this and TOTALLY REDEEM YOURSELF

[@T3hIluvatar]

"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

[@OverUnity7734]

You can tell he is in college , he has to drink everything. :)

[@re8nifle]

The water was boiled for safety. Wait... wrong channel...

[@MackinCheezy]

re8nifle 😂

[@Nyerguds]

well, given the fact both boiling and freezing tends to make cell membranes rupture, this _might_ sterilize it... maybe...

[@chadcooperconsulting]

good demonstration of the statement "boiling is a cooling process".

[@doctoredable]

Physical Chemistry was my favorite course in college.Thanks for bringing back some great memories from 43 years ago.

[@marcelpowerroxx]

Could a vacuum chamber be used to cool beverages down quicker than a normal freezer would? How do carbonated drinks behave in a vacuum?

[@ScienceDiscoverer]

They explode!

[@blingames1163]

In Soviet Russia, water boils frozen!

[@fleshtonegolem]

That was a great experiment :) Thank you for your videos!

[@TheBdd4]

Thanks for an excellent and interesting experiment!

[@jsdesj]

Hi Cody ! I was wondering if you could show us where you work/how to make a properly safe lab

[@duncanw9901]

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.

[@duncanw9901]

That pressure gauge is hideously inaccurate for the kind of work you do.

[@exoc1]

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. :)

[@1pinosos1]

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?

[@TheToric]

J Paino never more than 1 atm of pressure.

[@hrgwea]

+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.

[@mikeperth8027]

Cody, Love your videos mate. Keep it up. Well done on providing an entertaining perspective on science. You remind me of our very own entertaining scientist here in Australia, Dr Karl. Albeit a younger version.

[@azazel1667]

hey 500th video congratulations

[@robotbanana4261]

I liked that annotation when you took a sip of water.

[@dummypg6129]

he tries to prove something, which is nothing tho.

[@SephBane]

That wasn't normal water, there is cyanide in it. Cody puts a little in all the water he drinks.

[@theCodyReeder]

You know I actually used to do that for high altitude training.

[@dabigb1243]

That must have been a small amount then, and even if it is, wouldn't that have long-term effects?

[@rcksnxc361]

Cody'sLab wtf

[@kpag3030]

Seph Bane huh?

[@mirmalchik]

gotta build up that resistance lol

[@whispergb]

Nicely done!

[@saxparilla2660]

The world needs more people like u

[@swiftnade_]

This was intriguing... and your watch was at 11:11

[@Volvith]

Cody, you have to understand that you taking a sip of a clear liquid does not prove it being safe at this point... xD

[@kennethwcole2879]

Happy new year codey

[@SilverWolf-he6zh]

This here, is whats science is all about, Experimenting and Discovering, love the video man! very interesting! thanks!
