In this Instructable I will build a drink cooler machine that can chill your drink in just 60 seconds! Based on the concept of the "Cooper Cooler", I will show you every step of the build and how you can make one by yourself using very cheap materials.

Step 1: How It Works

How is it possible to cool down a drink in just 60 seconds? The key is to remove the heat from the liquid inside the can. By using two electric motors, one spinning the bottle and one pumping ice water onto the drink, the warm liquid in the center will move outwards causing more of the warm liquid to interact with the cold water on the outside. Basically the icy water on the outside will absorb a lot more heat and way faster than something like a freezer or an ice bath.

<p>When I lived in Alabama, I sometimes had my beer start to turn slushy before I could finish drinking it when I was working on projects out in the barn in winter.<br><br>I started keeping a few beers in a 5 gallon bucket full of water - when I wanted one, I had to chip off about 1/4&quot; of ice (I only drank one per night, which is why they sometimes froze before I finished them).<br><br>Drinking liquids even below freezing (when they have other than just water in them) is not dangerous.</p>
9.8&deg; isnt exactly drinking temperature though... how long does it take to get to 2&deg;? <br>Is it even possible?
<p>No drink should be served at 2&deg;C. Most drinks will be served at 6-11&deg;C. Any colder and it will burn.</p>
<p>LOL. I don't know why but I find your reply hilarious! Nice one! :-)</p>
I was genuinely just curious, and completely baffled at the response that 2&deg; would burn, especially since thats what damn near every fridge around here is set to! And not a burn in sight!!! Lol!
I would like to see you drinking beer at 6&deg;C!!!!<br>It can go under if you add a bit of ice on the colling fluid. <br>
Have you people never heard of slushies???<br>Maybe its because i live in a warm climate... but I'm certainly not alone around here in my love of cold drinks. The fridge of my truck is currently reading 0.2&deg; my drink sits against the condenser for over an hour before i drink it... i aim for slushy, but still drinkable (too long and it freezes) <br>If brain freeze is not a very real risk, it's too hot! Lol!
<p>And of course as everyone knows here in Britain we drink our beer warm...</p>
<p>Beers can be drunk at various temperatures. According to your preference of temp you dont like the taste of beer :) . Im an Ale guy so 12-14 is me.</p><p><strong>Very cold (0-4C/32-39F):</strong> Any beer you don&rsquo;t actually want to taste. Pale Lager, Malt Liquor, Canadian-style Golden Ale and Cream Ale, Low Alcohol, Canadian, American or Scandinavian-style Cider.<br><br><br><br><strong>Cold (4-7C/39-45F):</strong> Hefeweizen, Kristalweizen, K&ouml;lsch, Premium Lager, Pilsner, Classic German Pilsner, Fruit Beer, brewpub-style Golden Ale, European Strong Lager, Berliner Weisse, Belgian White, American Dark Lager, sweetened Fruit Lambics and Gueuzes, Duvel-types<br><br><br><br><strong>Cool (8-12C/45-54F): </strong>American Pale Ale, Amber Ale, California Common, Dunkelweizen, Sweet Stout, Stout, Dry Stout, Porter, English-style Golden Ale, unsweetened Fruit Lambics and Gueuzes, Faro, Belgian Ale, Bohemian Pilsner, Dunkel, Dortmunder/Helles, Vienna, Schwarzbier, Smoked, Altbier, Tripel, Irish Ale, French or Spanish-style Cider<br><br><br><br><strong>Cellar (12-14C/54-57F):</strong> Bitter, Premium Bitter, Brown Ale, India Pale Ale, English Pale Ale, English Strong Ale, Old Ale, Saison, Unblended Lambic, Flemish Sour Ale, Bi&egrave;re de Garde, Baltic Porter, Abbey Dubbel, Belgian Strong Ale, Weizen Bock, Bock, Foreign Stout, Zwickel/Keller/Landbier, Scottish Ale, Scotch Ale, American Strong Ale, Mild, English-style Cider <br><br><br><br><strong>Warm (14-16C/57-61F):</strong> Barley Wine, Abt/Quadrupel, Imperial Stout, Imperial/Double IPA, Doppelbock, Eisbock, Mead<br><br><br></p><p><b>Hot (70C/158F):</b> Quelque Chose, Liefmans Gl&uuml;hkriek, dark, spiced winter ales like Daleside Morocco Ale. </p>
I write before see the video.. sice you have put ice on it you should try another cooling fluid, or as someone say with salt you can get liquid water at above -5&deg;C
6-11&deg; doesnt even meet food hygeine standards here! 2&deg; is most common, but cold items MUST be kept below 4&deg; (hence 2&deg; allowing room for error)!!!<br>At the temps youre suggesting I'd throw the drink out... way too warm to drink, I prefer the colder the better.
<p>Shake Me Up! </p><p>I'd be pretty careful opening any can I put through all that. Considering what you did, I'm surprised that the can didn't get shook up. Pretty neat idea, though. I mostly just put my soda in the fridge and not touch it for a few hours.</p><p>I guess I'm lazy.</p>
<p>Very nice build. I also like your tidy shop; looks like a great work space.</p><p>Build_it_Bob</p>
<p>I think your explanation of the underlying Physics needs refinement. For a can sitting submerged in an ice bath, there are basically only gravitational-induced convection currents aiding heat transfer. These currents move relatively slowly, both inside the can and without. </p><p>With the spinning can and liquid falling on it, there is much enhanced convection. On the un-submerged part of the can, there is a &quot;falling film,&quot; which is very thin, and so, presents greatly-reduced resistance to heat transfer, by virtue of its thinness (you can study &quot;falling film&quot; heat transfer on the web). Below the ice water surface next to the outside surface of the spinning can, again, the spinning maintains a relatively thin boundary layer next to the can, which greatly increases heat transfer by virtue of its thinness. Judging from the rpm you spin at, I'd guess that this boundary layer is &quot;Laminar.&quot; </p><p> In your explanation, you say that, inside the can, warmer liquid moves from central portions to outer, colder portions. That needs more analysis, since cooler water is denser than warmer water (true for most other liquids). There thus tends to develop a stable stratification, with the inside liquid rotating as a rigid body, once past a short, initial period when there will be a thin boundary layer, as there is on the outside of the can. Thus, heat transfer from the warm liquid inside the can will start at a larger level once you flip the switch, then settle down to a minimal level, with the dominant mode of heat transfer in that case being pure conduction, without much help from any convection. </p><p>Thus, the heat transfer enhancement because of the thin layers acting on the outside surfaces of the can and for a short time acting on the inside surface of the can are enough to overcompensate for any inside heat transfer that is reduced because of the rigid-body rotation of the internal liquid. </p>
<p>I'd love to buy one, not sure I want to make one, don't have the kind of nice large workshop. As it took less than ten minutes to make one I guess I could drive up to Trollh&auml;ttan from &Auml;lv&auml;ngen and see it being made. ;-)</p>
<p>You are always welcome for a visit :D</p>
Tack Simon, beh&ouml;ver du elektronik-hj&auml;lp s&aring; &auml;r det bara att fr&aring;ga.
<p>Skulle jag kunna f&aring; din mejl?</p>
<p>alias h&auml;r och sedan snabel-A gmail.com</p>
<p>Truly amazing! I'm totally impressed with your creation and the video itself. By far the most easily watchable I've seen. Great balance of providing full detail without delay. I love the way that you demonstrated the effectiveness with the temperature test. I'm inspired.</p>
I like this
<p>Good idea but I think you could have problem with fizz drink. Have you tried with beer or coke ?</p>
<p>Actually there isn't! Which is awesome, I guess.</p>
<p>Wow this will make my next outdoor trip more extravagant</p>
<p>reat idea, it's just what i need in hot summer day</p>
<p>Very nice. One thing you can do is to add salt to the water to make the ice melt faster making the water colder. I just might have to build one sometime.</p>
<p>Sweetness. now I need to super size this for a ceg!</p>
<p>Awesome Project! I love the whole concept of it and your video was well put together. Nice shop by the way.</p>
That's really neat! I'm surely going to build one
