I know you all wanted the liquid nitrogen in the machine, but the liquid nitrogen just cracks the plastic due to the quick cooling.
How you know that it cracks the plastic in the machine is a story I want to see...
I want to see you put salt in the water in the machine.
What about salt in the machine, would the salt destroy the pump.
d
Also, dry ice and salt water in the machine?
(CZcams bug won't let me edit my comments, but an extra comment helps the algorithm right?)
If I saw that machine in a store, I would think it was a gimmick product that wouldn't work. It's incredible to see it function so well.
Yeah agreed. Would still be a bit of a waste of money for me, but nice to see it performs well.
I mean, it's still a completely useless gimmick product that shouldn't exist.
ikr, it's very impressive and very useless at the same time. Who drink soda at 4C anyway? I don't drink anything colder than 15C.
Yeah I just don't see the draw. Just get a jar, put some water, ice and salt in and submerse it for a minute to minute and a half. I'm not that desperate to have a specific machine to cool down an individual can. Not to mention all the unwanted agitation if you have a carbonated drink.
@@v0ldy54 I think it's very useful in the right (very specific) setting. I've gone to a beer store attached to a movie theater where they have these. If you buy an unrefrigerated beer they'll chill it for you so you can drink it with a movie. It'd be pretty silly for most people to have this at home, but they have 2-3 of these and they work great.
There is actually another factor I think helps cool down the liquids so well. Unlike liquid nitrogen the machine is trimmed to never allow the temperature to drop below 0C so that ice never appear inside the bottles. I think avoiding ice formation is the biggest key to fast cooling, closely followed by steering.
I wholeheartedly disagree, I love partially frozen coca cola, but also if you can get that at least the pencil eraser ice will do the trick.
@@realanarchobillIce insulates. The comment wasn't about taste.
@MatthiasGorgens I'm just confused as to how trimming a machine effects temps myself lol
I bought one of those Cooper Coolers back in 2016 and absolutely love it. I actually stopped keeping drinks in the fridge and exclusively used that for probably two years, until I lost the power cable for it
How much
@@MLL65 I wanna say they're like $50 new
@@ParallaxSound315
thanks a lot
I think the most interesting thing was that spinning the can's didn't stir them up, only side-to-side vibrations did.
Yeah the liquid doesn't move the way the container does. If you turn a glass of ice water in your hand, the ice will barely move
I mean, if you "knock" with your fingers on the top of a can you were shaking before, or even spinning it upright on a table, the bubbles inside move to the top (due to pressure change) and will most likely even save your can from squirting out your drink.
@@D4ngrs That's a fallacy. If you don't tap and wait the same time you get the same result.
@@BooBaddyBig I saw a video where they tapped the sides a few times and that prevented the burst. They said the -Bible- ..I mean _BUBBLES_ , actually attach to the sides inside the can, and tapping releases them.
I haven't tried it, but maybe it's true.
@@BooBaddyBig not really, although u want to tap the side of the can, and not the top. oxygen gets stuck to the side of the can when it's shaken, which causes it to rush out when the can is opened. if you tap the side, the oxygen bubbles gets released and moves to the top where it can be released without bringing the soda with it.
Works for a cold swimming pool, too. If you're in at night and the water is still, if you don't move, the water warms up around you noticbably.
Maagiccc!
I was just going to say this :)
It's the same principle as windchill also.
That's funny, that's what the survivors on the Titanic said...NOT!!
@@justrelaxing1501I’d imagine the ocean is not still enough for that to work
There's a limit to the amount of heat transfer due to surface area, and when the liquid phase changes to ice - it's ability to transfer heat is even less. So the best way to cool it is to have the largest flow rate of the heat transfer medium over the surface. The can rolling machine does the trick, but it could probably be made simpler and cheaper than the one here.
One factor also to consider with the bottle is the thermal conductivity of the thin aluminium can is likely way better than the plastic helping it to not only cool faster but feel cooler to hold… meaning cans also warm up faster.
The salt and ice method may also make a thin ice layer that slows down the cooling process. Just adding a bit of salt to the machine might be a winner.
Was thinking the same thing...
I commented the exact same thing before reading your comment, sorry. 🤣
Salt lowers the freezing temperature of water. The water becomes somewhat colder than 32F.
Problem is that'll start messing up the internal portions of the machine with layers of salt left over after each use.
@@NukeMarine Good point but not if you run clean water through it after each use, I think at least.
I've owned two of the Cooper Cooler. Both of them failed after a few months of regular use. I never left water in the unit and followed the directions. I loved it, but they were too expensive to keep replacing.
For occasional use, especially for wine, it works really well.
Yeah. The best and cheapest method is just to not forget to cool it way before you're going to drink it.
its also cheating, you have to pre freeze the ice water. just put the ice in your drink
@@SpanishGarbo the next best and cheapest method is swirling the bottle in the ice bath by yourself
no warranty policy?
@@Blox117. If you add ice into your drink, it waters down the drink.
As an engineer, this device looked very satisfying in operation. Clear indication of a good thermodynamic grasp
Another factor that helps the machine is that when the can is spinning, the parts of the water that have a higher temp gets pushed to the outside from the centrifugal force. Years back, a company was prototyping a spinning heatsink(can't remember the name), and thermal imaging showed how the centrifugal forces flung the heat to the outer rim of the heatsink.
You should repeat your liquid nitrogen experiment but make the can horizontal before spinning it (e.g. Put the nitrogen in a tub or something). That way, you will hopefully avoid the situation where there's ice at the bottom.
Or he should just place liquid nitrogen into the machine and see if it works better
@@originaldenis6110 Wouldn't work in the machine. No "should just"
And compare it with the machine filled with ice+salt+water
@@originaldenis6110
And completely destroy the machine.
I was going to say the same thing -- spinning the can on a vertical axis doesn't help, because once all of the liquid is spinning at the same rate, it won't do anything about the boundary layer, and it also won't redistribute the heat (start-stop-reverse spinning on a vertical axis would help a little bit, although still not as good as horizontal axis spinning).
Best way to pour drink in glass. Put ice in cup, wet ice with water to get rid of nucleation sites, pour out water, keep drink as cold as possible, slowly pour drink over ice. Makes for the coldest drink with the most carbonation.
Oh! That's smart about getting rid of the nucleation sites! When did you figure this out about getting rid of the nucleation sites? From the Mentos and Coke videos? That's when I learned about nucleation sites, though I didn't think to put it into practical use. :D
@@huyked actually I got pissed when a poured a beer in a frosted glass and it foamed up. Haha. Then I realized the same thing is happening on the surface of ice.
This is a topic that is studied by mixologists. For open fluids, there are different techniques for a chilled mixture ie. stirring or shaking the fluid in a container with ice.
Some major variables: the size of the ice, temperature of the fluid, temperature of the container will normally affect the dilution of the fluid - before the mixture reaches equilibrium (its below freezing).
The reason I mention technique for mixing: technique will result in different rates of dilution / results as well. Examples:
Stirring fluids into a mixture (usually) helps to prevent unwanted emulsification to preserve the initial fluids flavor (nodes), but it also takes much longer for a fluid to reach equilibrium.
Shaking fluids comes in different forms - most specialists will use a “2-point shake” resulting in fluid rushing from on side of a shaker to another, circulating.
The main idea of the “Japanese whip shake” is to incorporate a rotation, so the fluid can circulate in the perpendicular direction inside the shaker - theoretically resulting in a faster equilibrium.
Notable mention: shaking also helps to incorporate air into the mixture, which usually is good for citrus.
Alternatively, if dilution is a concern, and we wanted to chill a fluid, the alternatives have their trade offs…
In a container, rather than using ice to cool a fluid, there are options that don’t melt (ie stones): the trade off is [high-key throwback to the ActionLab previous video] water retains its cooler temperature (MUCH) better than any stone could.
Or chilling the fluid in a cool environment (fridge/freezer): takes a long time (is why you made this video).
The fastest way I’ve been able to chill a fluid in a closed container, is by submerging the container in water/soda-water with ice. It gets really cold really fast, at an affordable price.
Cheers!
Very well made text, were you referring to sodium hydroxide in the end? Cold saturated plus ice is that it?
@@fss1704 Pretty sure he's talking about baking soda, sodium bicarbonate. Less finger-melting potential.
@@DFPercush i rather stick with calcium cloride, that stuff really cools is reusable and che@p.
Usually I put one in the freezer near the fan and turn it to coldest setting and I noticed if I rinse the can off with cool water first it helps the can get cooler faster. In six mins I have a cold can of soda water, but not as cold as that machine or the liquid nitrogen here. Great Vid!
I think another factor is the density of water, which can carry much more heat than even liquid nitrogen, which tends to instantly turn into ultra low density nitrogen gas at this ambient temp.
Might work better if in a cryo chamber cold enough to keep the nitrogen liquid.
Love you Mr Action Lan guy!
True, and that's why it doesn't freeze your skin if you accidentally drop some on you
Water has an insanely high heat capacity.
@@ilikemitchhedberg I'm sayin'!
facts
@@ilikemitchhedberg Oceans have such an impact on world weather because of high specific heat capacity of water. Without World Ocean, the climate on Earth would be subject to extremes. Atmosphere also has influence in circulating heat but it is the World Oceans that function as a huge heat engine dwarfing everthing else
The Action Lab has done it again. These experiments are on an entirely different level.
lol
I do hope you’re being sarcastic
True, the experiments are amazing!
Now, if he only used metric instead of imperial units, he might actually qualify as a professor at university 😆
@@user-bp6eh7en1v He did use metric units at least once.
@@user-bp6eh7en1vI was like, why are we using "cups"
what about the evaporative factor? does increasing the total liquid surface area of the water flowing around the can cause an evaporative cooling effect? if so how much might that effect it, and would there be a way to increase the effect?
Definitely fun to watch. What an ingenious device for cooling drinks.
For the ice and salt method you need to use ice to salt about 1:1 - this will give you in the ideal chase -20 °C or whatever that is in F 😅. We regularly used this in the lab when we did not want to go for liq. N2 or solid CO2 - sort of the cheap option 😂.
I use a a much larger metal bowl that can hold 3 cans and will cover them fully when the ice is added over them and then filled with cold water. Throw a good helping of salt on top and stir it slightly to move the salt around. The first can is noticeably cold within a few minutes and the 2nd and 3rd ones are ice cold when I go for to them Doesn’t use much more ice but than doing one can but cools 3 without additional work
damn 1:1 is a lot of salt. But it actually drops the water temp to -20 C???? That's actually really cool
-4 degrees fahrenheit
It’s probably around 0°F! Fahrenheit calibrated the 0 point of his system to be the temperature of saltwater and ice because that was the lowest observable temperature in nature known to Northern Europeans in the 1700s.
can you keep the salty water and reuse it?
I'd be interested to see the machine with dry ice and isopropyl alcohol. It also has an advantage over liquid nitrogen because it doesn't have leidenfrost effect.
We used ice/salt/ethanol in the lab, with that we were able to get to -20°C quite easily. With dry ice and acetone you are able to get to -75ish°C, though we only did that once.
Not only is this a good scientific demonstration, but its also a good advertisement for that machine. I think I want one
Most likely why you didn't see much of an improvement with the liquid nitrogen method is because of pressure. The bottom froze first, which increased the pressure in the can (which you saw multiple times when you opened it). Increased pressure = higher temperature. At some point, the pressure is too high to freeze any more soda and the can _has_ to explode in order to reduce the temperature further. Another issue is the temperature gradient, and if you were to mix it or let it equalize, you would probably see the temp just a couple of degrees above freezing.
Had you opened the soda before you put it in the liquid nitrogen, you would have soda everywhere, and what was left in the can would be solid.
Maybe you should always give the temperature in °C as well, not just in the beginning, that doesn't make sense at all.
well he’s American
But, wouldn't be easier to store salty water in the freezer (always liquid) at -18 C, you just need to put the can in the water for 20 seconds. Then you can reuse the same water.
There's a DIY video where someone uses a power drill to spin the soda. That could be incorporated.
Good thinking but no, it is the spinning of the can and water being poured constantly that pulls the heat energy away. You could put the whole machine with salty water inside your freezer, but yeah.. how much effort are we going to put into this "problem" ;)
I bought my dad that drink chiller machine for Father’s Day a few years back and it work’s absolutely incredible.
I have one of those, it´s a great machine! The pannel on mine went bad a couple of years ago, so I bypassed it and now it just starts working when you plug it on the wall, but still works great!
James I love your constant enthusiasm and clever ideas, youre such an amazing educator. I want to see the drink... Colder, with salt water, I bet that does even better.
Ye, really cold salt water .. cmp. to nitrogren... why does noone do that, hmm. bringing water down to -100°C or so ?
The way I make a drink cold quick is to wet a paper towel, wrap it around the drink and put it in the freezer for a few minutes. It actually works. If I had ice cubes which I don't, I would just put the ice in a glass and pour my drink over it.
I should have scrolled down before i posted. Same method here.
I find it takes about 10 minutes. Once the paper towel is frozen, the drink is pretty cold. It's about three times faster than putting a bare can in the freezer.
Got a cooper cooler for my father in law...that thing is awesome.
Thanks for the video, sir. I need to get me one of those.
Very useful for all those times when I forget to put things in the fridge but remember to keep liquid nitrogen on hand!
That happens to me all the time 🙄
@brandon3872 Yea, happens to me all the time too. And my power drill is always fully charged when that happens. It usually is not when I'm about to actually drill something.
or thirty ice cubes!
*Yeah, I just run down to my local liquid store and pick up a keg of liquid nitrogen when I'm out or low on N2.* 😂
Hey man, is it possible to include into the video, like labels when you talk, about temperature degrees, in Celsius too as you bigger audience worldwide don't use F⁰?
That way will speeds up the comprehension in temperature related videos.
Tks
I don't know how significantly this would help, or whether it would mess up the electronics, but you could put the entire machine in the freezer for a while first, that way the otherwise room temperature channel that the water is being pumped through wouldn't slightly warm the iced water.
If I don’t have a cold can in the fridge ready to go, then I usually wrap a warm one in a paper towel, then wet it in the sink, then stick it in the freezer for 20m or so (with a timer set). Works pretty well if you’re willing to wait a bit
The most convenient way to make a drink cold is to wrap it in wet papertowel and stick it in the freezer for 10 to 15 minutes. Works like a charm. It's not the quickest, but it's the easiest!
Have you tested without the wet paper towel, and notice a temperature/time difference?
This!
@@huykedhaven’t measured the actual temp, but I have tried with and without the wet towel for the same time and it makes a huge difference
@@lkyuvsad I keep an ice bucket with water in my garage fridge and just toss sous vide meats in it to chill. I've tossed drinks into it with good results.
@@huyked It works much better with the wet towel. Water is about 25 times better at conducting heat than air. The thin layer of cold water in the paper towel zaps the heat out of the can faster. I've been using this trick for years.
Please do wet towel soda can cooling with different fabrics (napkin/toilet paper/etc)!!
I heard too many to count!!!
Bicyclists sometimes put wet tube socks on their water bottles. It's a different effect, but the tube sock would probably be a nice touch.
I've had that thing for years! Still does a great job
Brilliant and informative!
Salt water in the cooling device with the ice. Bet you can get it to below 37 even more efficiently.
Salt works to lower the freezing point so it works with ice only. I don't think it will have to do anything with water in liquid state.
I know you use Fahrenheit because that is where you live, but it would be handy even if there was some text on the screen that would flash the temp in Celsius when you give a temperature reading. Saves me having to pause the video then go to my web browser or calculator and then have to convert the difference. Good videos as always, been watching you for years.
I use a fish tank circulator(like an underwater fan) for quickly cooling or defrosting things. it'd be interesting to see if having the bottle/can move as well would make a difference
The can/bottle was moving from what was shown in the video. It sounds from little rubber o-rings on the shaft the container rests on.
Damn Daniel back at it again with the warm cans! 😂😂😂
Love your channel!
This reminds me of those speed defrosters which are super efficient heat pipes that wick heat into whatever is laid onto them very efficiently.
For the liquid nitrogen you should spin in left and right so the liquid in the can can mix with the outward cold liquid.
I like your sponsors they could be useful in most situations
Large enough container full of ice water is the most convenient and works great
I was really hoping he would put liquid nitrogen in the cooling machine 🤣
Same. It'd probably ruin the plastic, but it would still be cool to see.
@@DavidPlassIce see what you did there
@@chevvvv It brought tears to my ice.
@@chevvvv Ha! It was unintentional but I'm glad you appreciated it.
Sadly I'm not cool enough to make an ice pun
The control, I think, for this experiment would be to put the soda in an equal sized volume container as the ice spinning machine, fill it with ice, close the lid, and leave it for one minute. The temperature difference between the two tests, one spinning and one not, would then tell you the significance of lowering the temperature because of the spinning.
the spinning and the effect the water is running
It's like 8 times faster at least if not more, convection is really crap to cool stuff.
You're always the man!
OMG! Thank you for the Celciuc. ❤
Based on your explanation at 7:39, for your method at 1:40 would it be better to submerge the can vertically in a tall container (like that thermos you used for the liquid nitrogen method) and stir the water around the can instead of spinning the can? The can can be held down with a magnet or a weight or something. By doing it this way you can keep your hands warm so it's a lot more comfortable. Also, you don't transfer heat from your hands to the can, there's more surface area of water in contact with the can, and you can stir water a lot faster than you can spin the can by hand (assuming you don't attach the can to a drill).
This is basically what I do and it cools a can of soda to colder than refrigerator temp in about a minute or so. I use a cheap plastic 2 liter pitcher with a tray of ice cubes placed around the can and then fill it with water up to the top of the can. Then I just spin the can from the top with the tip of my finger in a quick circular motion. It will spin pretty fast if you get it going just right and I would bet it cools faster than the machine as it uses less water and direct contact with the icecubes.
You can use a sous vide circulator in a large bucket of ice water to chill your drinks super fast. I use a large cooler for mine
Hah! I keep an ice bucket in my garage fridge, which I keep right around freezing, that I use to chill sous vide cooks. I've tossed drinks in that, too, but I hadn't -though- thought about using a circulator that way. Maybe an immersion blender in a bucket of ice water would work too.
@@CarbageMan both of my circulators go down to 32' so they don't heat at all, and you really don't need much circulation to keep that chill on everything
Hi mate, im learning to fly a paramotor in the uk, one of the things the instructor has said, us Latent heat, and how Latent heat is caused when clouds are made. Could you do a video about this please, and when someone gets out a warm shower, but feels cold, that is Latent heat, appreciated
Great video as always, thank you!
Alternative method: large bucket of water, ice and salt, and gently stir every couple of minutes.. That way you wont decarbonate your soda or beer from that fast spinning!
Fun fact: if you put warm water in a freezer it turns into ice faster than if room temperature water is used, and it is an open problem in physics. Can you test this?
People look at me crazy when I'm jumping salt and my coolers in the summertime for cookouts. But then when they grab a cold drink and can't believe how freezing cold it is I explain why. I've been doing this for a long time It is tried and true works awesome , salt, water, and ice in your coolers
It’s scary how many people don’t know about that
That makes no sense. If you have a cooler full of ice with drinks stored within it, they're going to end up being only slightly above freezing themselves, you don't really want them any colder than that. If you dump salt into the ice you would freeze them. It would be a shock to open up a frozen can of pop all right, but I'm not sure that's a good thing.
Unless you're saying you do this to quick cool them because you serve them to people soon after you put them into the cooler, that would make sense.
Of course that drink is going to be coated with salt water, and the first sip might be a bit briny.
I'd go with just putting the drinks into the cooler a little bit early rather than going through all that.
The trick I’ve always used with drinks is to pour it into a glass with ice in it and stick a straw into it and blow gently through the straw for several seconds. Gets the drink cold extremely quick! The disadvantage is obviously watering the drink down, but I find most soft drinks are already too sugary, syrupy, and sweet for my taste so I like them watered down more anyway so that’s just another win for me. It wouldn’t be for most people, though.
Also injecting your drink with a big dose of your breath. To each their own
interesting since the spinning sideways motion has the most surface are contact with the fully enveloping water and the turning of the inner liquid that allows it to turn more hot liquid to contact new cold liquid instantly. thats why the topside nitrogen spinning didnt work. since only the spining bottom had contacr with the cold liquid and the instant freeze removed the possibility of free moving fluid in the can to spread the cold heat dissipation across the inner and outer surface. retaining it at the bottom. a very fascinating effect. I like to pop a drink in the freezer for 10 minutes and turn it every 2 to 4-5 minutes, personally here in the desert. and sometimes it causes heavy frost in my only mini fridge
We used to spin warm bottles of beer in coolers of ice to quickly cool them down to drink back in the early 90s
you could probably use the oddball can spinner thing with dry ice and everclear or ISO, rather than normal ice and normal water. It'd make it cold as hell in like 15 seconds or less.
It would break the machine, alcohols destroy plastics, it makes them brittle. Should try with ethylene glycol
Let's get him to 10 Million . He deserves it!!!
Now that's some crazy engineering stuff!
when you give the cool water velocity, its heat transfer coefficient increases. Here the machined moved both water as well as the soda can so the heat transfer rate increased a lot. So faster and effective cooling.
For the liquid nitrogen, would you be able to just cool the top of the can? The cold liquid would fall and the warm liquid would rise to be cooled. It might help with the temperature distribution (in the same way kettles only heat the bottom liquid).
Am I the only one disappointed he didn't try filling the cooler with liquid nitrogen?
That might broke the machine
My method for last minute chilling of the soda beverage was to pop it into the freezer right up against where the cold freezer air would have direct contact with the can/bottle, and periodically swirling the can/bottle in a circular motion making sure not to shake the contents to even out the temperature. Given the apparatus that was being used spun its contents with fresh cold liquid poured over it was pretty much my method but on steroids. I now want one of those.
Can you tell me, what kind of CFD software do you use?
Pour it into a glass with ice cubes in it. Yes it slightly dilutes the beverage but most sodas are too strong in the can for that reason.
Just plan your life a few hours in advance and put them in the fridge.
Boo
Finally! The solution!
“Icy bottom” had me rolling for some reason lol
When I need to quickly thaw fish or shrimp or some such, I put the unwrapped items in a mixing bowl filled with water, then float this in a sink full of hot tap water. It takes maybe a half hour. I’ll have to figure out some way of adding spin.
Why not add salt to the machine just to see if it improves it any further or pour the liquid nitrogen instead of ice.
Please use metric units 🙏
I have that same machine somewhere downstairs. I got it for free from this place where they were gonna chuck it out. I thought it was cool, and it really does cool down cans super fast. You can do a full bottle of wine too. One thing this video doesn't show is that the thing is really loud though, like vacuum loud, lol.
You’re great I love your content
I wish you would’ve added salt to the machine to see if that made a difference. Also adding liquid nitrogen to the machine would be interesting, but would probably break it lol
I'd say it would definitely break it lol 🤣 as someone that has shaken a closed soda bottle with liquid nitrogen and water. I'm 100% sure the water pump would explode from the rapid expansion caused by the agitation and embrittlement from the cold.
Please use METRIC units for scientific experiments
I wasgona say surface contact is important but u covered it brilliantly
Can you try putting a can in a basin with water and use pressurised air can?
The experiment goes like this:
Dip the soda can in the water and then Dip the pressurised air can halfway in (with the nozzle out of the water) then start continuously releasing air from the can with air.
The thing I want to figure out is whether the lowering of the air pressure in a APC (air pressure can) can lower the temperature of the body of the APC enough, to make it form ice, or atleast cool down the water.
I believe we were taught something like this in university, but it was a long time ago. It's ok if you don't want to try it
The DUH files: In the winter, the porch is a great cooler. Even a closet on an outside wall keeps drinks cooler than room temp. Cold enough in my outside wall closets.
AND in summer? Set beside the vent where the A/C blows.
DUH, eh? My aunt used her winter porch as a fridge extension for all the extra foods needed for gatherings.
The greatest natural fridge I have seen was on a property in VA. A rock builder built a rock 'cave' box area underground (you walked into it) and a natural spring ran thru the rock box area. The spring water was always cold. And voila! His civil war era fridge was still standing and functioning today in 2023. I want that one!
Awesome video. Thank you! ✌🏼🙏🏼🖖🏼💕
My Dad once showed me a trick where you just spin a drink in ice for about a minute... Similar to your method, but no water or salt. Works great!
I think the machine could spin the can 10 times slower and it'd still cool the drink just as well. It would just avoid shaking the contents and building up pressure. The water flow is the main thing, and turning the can helps somewhat but it can be quite slow.
maybe you should try making a contraption like something like heatsink but made of tubes where water will flow and put it in ice water to see the results.
Can we get the temperature in normal units normal people use?
americans believe everybody use they're units
No, learn ours.😊
Please use SI system
I was looking for this comment
yes please. the freedom units suck
I do similar to you... But I fill half way a pot with ice, large enough to hold up to 4 cans. Mix in up to 4 cans and add water to near the rim. The cans should be mostly submerged in the ice water. Then with both hands I can spin the cans fairly quickly. Works great and chills multiple cans in a couple minutes. If I'm not in a big rush I can just let the cans sit in the ice water. Usually is ice cold in 10 minutes.That gadget is better for a single can, but not so much when you need to chill multiple
Suggestion for a related experiment: wrap the lower third andm of a can with some layers of adhesive tape. Then submerge this and a reference can for some minutes in an ice bath.
See, which one comes out colder. The one with the tape should have more internal convection, not only diffusion. Therefore, despite the reduced contact area due to partial insulation, it might be colder.
throw it into liquid nitrogen.
Fahrenheit. lol
Also to include that water has the highest specific heat capacity than any other substance
(with very few exceptions)
Great demonstrations! You missed telling the temperature in Celsius a couple of times though.
there's a spot you can bring the temperature down before start getting ice and then when you open the lid and releasing the pressure it gets a PERFECT ice gel drink.
Happens so rarely that i need to find the correct way
Interesting to see the Leidenfrost effect on liquid nitrogen since the table is so hot in comparison
I usually wrap a wet towel around my can or bottle and put it in the freezer for 15-30 minutes, depending of the size of the bottle.
The evaporating water helps A LOT in the cooling process
Here the running water in the tap is +2c or so if you leave it running so for soda cans putting them under running water is the fastest way of cooing them I have access to. Takes about 1 min to cool a can down that way and 3-5 min if you want it really freezing cold. Another alternative is put the can in the deep freezer but that is much slower and take 30 - 40 min.
Memory - in Kansas in 1980s, I think the government liquor stores would only sell room temp beer. There were four of us. We put four bottles in a bucket, ice, water, salt, and just held the top of one bottle and turned the whole thing. In 2 minutes it was good drinking temperature.
My preferred method is wet paper towel wrapped around and tossed in the freezer. It's likely not as fast as these, but it's usually good after ~5-10 minutes.
this is the equivalent of active (convective) cooling with air, which works much better. except you are moving the liquid inside also so the effect is greater
Have you tried cooling it down by putting it in a bowl of water and then the bowl in a vacuum chamber? If the pump is powerful enough, the water boils down to 0°C in seconds and keeps boiling until everything is at 0°C / ice if you get below 6mbar / triple point.
