Why are we always so watery when it comes to ice? It would seem just as well to cool a large, flavorless stone in the freezer (or, even better, in something far colder than this environment), and place it in the drink to be cooled. It should be large to prevent swallowing, and it should be a mineral
that will not dissolve in the drink.
This can be done using current technology.

Actually, it has a lot to do with thermodynamics. Your freezer will keep the stone at, say, -5C. Your drink from the fridge is at 3C. So the rock will only provide 8C times its specific heat capacity, which won't provide much cooling. |
|
|
Ice, however, goes through a lovely solid-liquid transition when rising above 0C. This transition requires quite a large heat increase. Since it gets this heat from the drink, that's what keeps your drink nice and cold. |
|
|
I think the heat required to melt ice at 0C would be something like 10 times that needed to raise the ice from -5C to 3C. Thus, you need ice. |
|
|
You can try this yourself. Put a rock in the freezer and see if you can hold it in your hand till it gets up to body temperature. It's not that bad |
|
|
Now try this with an ice cube. Even just getting all the H2O to a liquid at 0C will make your hand pretty cold, much more so than the rock. |
|
|
It's also useful that the warmer
H20 becomes liquid, thus allowing
the cold core to keep a high rate
of 'cold transfer' into the
beverage. With a non-melting
solid, the outer layers would tend
to act as an insulator. |
|
|
Besides, it is my firm belief that
refrigerators in this country are
strong enough to sufficiently cool
my beverage. That's why I always
specify "no ice." 9) |
|
|
I just heard on the radio that drinking cold water makes you more stupid, temporarily. Energy is diverted from your brain to your digestive track in order to heat up that water. |
|
|
The points about ice vs. rock are quite good. The idea is to prevent the drink from being diluted. I agree that ice is a better coolant if you don't mind the drink being diluted gradually. |
|
|
Note that I suggest that the stone be made cooler than freezer temperature. Thus it could have more cooling power than ice, though for perhaps a shorter duration. |
|
|
If cooled too much, the stone would cause the liquid around it too freeze. That is why the stone would be quite useful for alcoholic drinks, since the alchol will freeze only at a temperature colder than ice can provide. |
|
|
frozen grapes work great for me. And then you have a
fruity treat at the bottom of your glass when you're done. |
|
|
Or else you can pre-freeze cubes of whatever beverage
(assuming non-carbonated) you plan on drinking, so
melting won't dilute. |
|
|
[admin: fixed zippyanna's to point to similar resources. rmutt will find his own replacement; I don't have enough to go on here.] |
|
|
We have small plastic 'ice-cubes' filled with some kind of liquid. So, you freeze these in the freezer and put them in your drink. You then get the cooling effect (or heat-absorbing effect, I suppose) of the solid-liquid phase transition without having your drink diluted. Note: If you keep the Gin and Tonic water in the fridge anyway your G&T won't need so much cooling. |
|
|
Are there any dentists out there that would like to comment on putting stones in drinks?
When you got to the bottom of the drink, and the glass reached a certain angle, the stones would slide from the bottom of the glass...... |
|
|
How about you just borrow some old technology from A&W Root Beer? Don't add cooling stuff to your beverage - chill the glass itself to a subzero temperature! Works best with big, thick glass mugs like (not coincidentally)A&W rootbeer mugs. Some ice ends up freezing on the bottom of the cup, concentrating your drink. Heaven! :) |
|
|
In the name of science, I have done some experiments at home with this; it is advisable to not only chill the glass, but the drink itself beforehand for the desired effect to be achieved. |

The rock vs ice problem could be solved by supercooling the rock with liquid nitrogen. In fact, you could do this with ice also - you could probably finish your drink before it melted. Unlike the rock, the supercooled ice would probably not break your teeth. However, it might stick to your tongue. |

Bungston, Bungston, Bungston. No, no,
no. A small amount of thought and a
minor calculation would save you from
embarrassing yourself in this way. |
|
|
The latent heat of fusion of ice is
334kJ/kg, whereas the specific heat of
granite is 0.79kJ/kg/°C. |
|
|
Therefore, cooling a rock with liquid
nitrogen (at about 70K, or -200°C) will
give you only about 160kJ/kg of cooling
capacity, or about half that of the
equivalent mass of ice. Even cooling
the rock to within a midge's dick of
absolute zero will only give you about
210kJ/kg. |

How much is that in furlongs? (hint one parsec = 1.533879 X 10^14 furlongs) |
|
|
4.97 × 10^-7 furlongs. Assuming you
mean a standard English furlong. |
|
|
As opposed to the metric furlong? |
|
|
No, as opposed to the real, or Scots
furlong. |
|
|
Is it long-er (look Ma! A pun.) |
|
|
I just searched for furlong (to research pun material) and found the most fantastic unit of speed: Furlongs per fortnight! |
|
|
Trivial derivative unit. One furlong per
fortnight is 0.7776 pyads/ke. |
|
|
you can do this with regular water that is separated from the drink via a physical barrier |
