How to get that warm supermarket beer cold in 12 minutes
-
So it's a hot day and I want some beer but there is only one can in the fridge! So off to the supermarket I go with my shopping list: Cans of beer(warm beer as they don't have a cold beer section) Ice(2kg pack) Bag of cheap salt So when I got home I put the ice in a bucket, sprinkled a good amount of salt on top, added water and then put the warm cans of beer in the bucket. 12 minutes later - ice cold beer :-D (the salt causes the freezing point of the ice to drop and hence cools the beer super-fast) It just works ok!(to be read with a stroppy voice) :laugh: [Edit]slightly whinny sounding correction to my correction of explanation in brackets() above.

Interestingly there was a program on the Hairy Bikers (two Geordie chefs) the other day, where someone was demonstrating how that was used to make ice-cream or sorbet in the days before fridges.

It may not be quick but have you ever hear about using gasoline or other fuel? I do not know exactly how to do it as I was told many years ago. It seems it is popular in the army.

If you buy some chip dip and want to eat it cold ASAP, spread as much as you want on a plate and put the plate in the freezer. :)

The fact that you are lowering the freezing point of the water does not make the water any colder than it already is. Therefore, the beer does not get cold any more quickly with the salt than without it.
The difficult we do right away... ...the impossible takes slightly longer.

but the ice causes the water to get colder. and, while the thermodynamics is beyond my abilities to explain, Mythbusters showed the effect is real: http://kwc.org/mythbusters/2005/03/mythbusters_cooling_a_sixpack.html[^]

Yes my explanation is incorrect - and the explanation is complex(beyond my current ability to understand it..) However it does chill the beer faster than not using salt. [edit]I keep elephanting saying ice when I mean salt

My guess is this... With a lower freezing point, the ice will melt at a lower temperature. That means you'll have colder liquid. In the very least, the liquid will be able to conform better to the items being chilled. With ice, you have little air pockets, and I imagine gas is not as good at transferring heat (out of the items to chill).

as in warm beer :laugh: I think we have been influenced by our cousins from across the pond. Back in the 80's chilled beer was, pretty much, unheard of in UK pubs.

He's not cooling water, he's melting ice into water at a lower temperature, the liquid, now colder than 32 degrees, will envelope the surface area of the cans cooling it faster than just ice, or water, or both. Think of it as he's lowering the melting temperature of the ice rather than lowering the freezing temperature of water.

Ummm... what? :confused: How does the salt affect the ice? Somehow this reminds me of Monty Python and the giant wooden rabbit...

That can't be right either.

You are saying the salt does not effect ice? Have you ever experienced winter? Do you live in an area where roads are salted? Have you ever salted a frozen sidewalk? I've done it with salt and salt water. You can actually melt ice with salt, salt/water below the freezing point.

That is an excellent explanation:thumbsup:

Actually, this is a well known effect: If you salt ice the brine produced has a lower melting point than pure water ice, so it enters the liquid phase. There are bonds being broken between the molecules in the water-ice to do this, and this requires energy (taken in the form of heat) so the temperature does drop. I remember doing this as an experiment in school, it got cold enough to freeze moisture out of the air onto the beaker(though obviously we used thermometers for the experiment). This is worth a squizz[^] using enough salt gets down to -30oC
