How do you make ice WITHOUT a freezer?

Question

I saw a movie once ( Fitzcaraldo, based on a true story ) and he makes ice and amazes the natives.
I was wondering how this is done without a freezer.

And can I do it myself for fun...
Ya, I'm kind of weird.

It wasnt fake and he had no electricity .

I believe somehow he used the boat to supply the energy.

a quote from the movie I just found
"It works through a chemical reaction
of two different salts."

It is a " machine" he makes ice with.
He is in the Amazon.
There is a real way to do this.

I finally found the way all you who think it cant be true.
You have a pipe that forces air through it that causes the air to drop in temperature. Actually more complex than that . the entire uniot can be made for less than 500 bucks , and they ar egoing to try it in Africa for keeping vacines.

Williams, 26, knew that forcing compressed air through a hole in the middle of a pipe causes hot and cold air to flow from opposite ends, a phenomenon known as the Ranque-Hilsch...

Ranque hilsch

ITS A VORTEX TUBE THAT WAS INVENTED IN 1930 < I SAID THE MOVIE WAS FACTUAL YOU BAFOONS>

Answer 1

Newscientist.com has an article in their December 24 edition that describes making ice using an electric field, but you have to pay to get the archived article.

Answer 2

Make Ice Without Freezer

Answer 3

If you created a pressure vessel somehow, that could create ice at a higher temperature by increasing the pressure.

There is actually a temperature and pressure where you can get water to be in all three phases (ice, liquid, and steam) at the same time. If you are going to go ahead and get a device capable of making ice at room temperature, I say, shoot for the gold. Try to find a device capable of producing the "triple point".

Practically speaking, to make ice at room temperature (without a freezer or similar device), you would probably need equipment that would be even more complex, heavy, expensive, and just not practical. I mean, McGuyver might be able to come up with a way that wouldn't be as difficult, but that's why he got his own show, and I stick to Yahoo Answers.

One easy step toward creating ice would be to dig a hole 3-4 feet deep. I believe at that depth, it is pretty much about 50 deg. Fareinheit all year round. So by putting water in the hole you could cool it some (assuming you cover the hole so that the air doesn't warm it up) and get a little closer to ice. But I don't know what way would work to take it from water at ~50 deg F to ice.

As I continue to think about it, you might be able to do something with running the water through a special pipe or something, but I'm not sure enough about the mechnics of that to give a detailed

You compress a gas, which causes it to heat up, then wait till the container of compressed gas cools back down to room. Then release it suddenly, and the gas will take energy (heat) from the environment to suddenly expand and take up more volume. This cools the environment, and if you release the compressed, cooled gas through water (or in thermal contact with water, as in a heat-exchange system like a fridge) the water will freeze. You could do it with a kettle, a woolen sweater (for insulation) and a can of CO2, like for inflating lifeboats.

Answer 5

Put a bowl of water outside in below 32 degree farenheit.

Answer 6

You may be able to spray from an aerosol can like compressed air.

Answer 7

hmmm have a container of liquid nitrogen? pour it onto the water..but seriously you saw it in a movie? so i guess you think there is a jurassic park too as well as animation land.....

Answer 8

Wait until the winter or move to the eternal winter.

Answer 9

I wait for the winter

Movies R Fake !!!
