    The other day I bought a bottle of wine at room temperature and when I got home I wanted to have it chilled, but there was no time because I was hungry and had to eat right away, so I had to have my wine relatively warm. I was wondering on how to make an instant portable coolant that can chill or supercool anything in 5 minutes or less, sort of like the reverse of domestic microwave. It won't replace the refrigerator, it would just serve as a supercooler for food in room temperature such as drinks, warm ice cream. e.t.c. Does anybody have any ideas?

    Hahahhaha! If I can remember.. that would freeze anything rock solid.

    I don't know how long it takes to chill a drink with the product above, do you? And do you think it can also chill solid products like ice cream? For instance, you buy a piece of steak and you want it frozen instantly for delivery services or something?

    the trick here is not to pour liquid nitrogen over the substance but to have liquid nitrogen be separated from the substance by thin metal...so that the thing cools...but not so that it crystallizes.

    Thanks for that, I didn't know they sold those.

    Great find!

    Put the bottle in a bucket of ice mixed with rock salt. The salt will lower the temperature of the ice and cool the wine faster.

    I didn't know they sold it either, the 1.3 seconds of google searching payed off.

    Hi,To cool wine instantly without ice one needs a quick and easy endothermic chemical reaction.This can be done very easily and quickly using a plastic bucket, not an overly big one, just one big enough for the wine bottle to sit in comfortably with a reasonable amount of space around the bottle.Next put some water in the bucket,next dissolve a reasonable amount of citric acid powder in the water,next add spoon fulls of bicarbonate of soda powder..add a spoon full at a time...this causes the solution to fizz and release copious amounts of CO2...it is necessary to do this in a sink because the liquid will probably fizz and overflow the bucket.This is an endothermic chemical reaction that sucks heat from the environment as part of the reaction...this will cool the wine quite quickly...I'm not sure how many spoonfulls of bicarb of soda will be necessary but I think it will be noticably cold after about 5 or 6 teaspoons something like that.

    Yes, under the title of lemon juice and baking soda.

    However, you can use almost any weak acid in place of the citric acid, for example acetic acid (vinegar) will probably be much cheaper to obtain. However, make sure to use baking soda for the base, or you will most likely get an exothermic reaction, therby heating the wine!

    actually if you are not in love, hold it close to your heart, and all will freeze...

    Albert Einstein went partners with a guy whose name is not as easy to remember and patented a sonic cooler - a refridgerator that used carefully calibrated diffraction patterns in sound waves to create "held still" or "cooled" areas inside a box, where the sound waves cancelled.

    Like the dark and light bands you see from wave cancellation in light - the dark bands being the "cooled" areas.

    There were some technical problems - including the fact that opening the door while the thing was running would cause permanent hearing damage to humans.

    But speed of cooling would be a simple matter of power. AFAIK there's no commercial source of the devices.

    Supercooling is the process of chilling a liquid below its freezing point, without it becoming solid.

    you could...but you wouldn't want to.

    We used to fill a tub of ice and water to quick cool beer at the bar I used to work at. You could also put it in the freezer, being sure to spin the bottle occasionally to mix it up.

    on mythbusters, they did it with cans of beer and while the fire extinguisher was fastest, a cooler of ice and rock salt did the job in 5 minutes whereas even the freezer was about 45

    It doesn't have to be rock salt. Any salt will do. And just using ice mixed with water works almost as well. You can cool a can of beer in like three minutes this way.

    I've used this method (minus the salt) since college. It works great.

    I learned about adding salt on an episode of Mythbusters. The fastest way to cool the beer was using a fire extinguisher, but the icewater took just a little longer.
