How to get that warm supermarket beer cold in 12 minutes

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.

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.
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.

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.

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

Think of it like making a liquid ice (yeah I know). You are liquefying the ice without significantly increasing its temperature. So you have the low temperature of the ice plus the lot bigger cooling surface of the water for your cans.

Not in the way described.

I used to. I shiver just thinking about it.

Not if I can help it.

If you are just being technical about the use of the term melt, then just say it, otherwise retreat to below the bridge hence you came.
No, but the salt affects the water not the ice.

I think you mean "whence". :-D
