An Idea for a Worth Chiller

Sorry I am at work so I was being brief. Right now I use a 10' copper tube to put down in my wort. One end is hooked up to a water hose and the other end drains out on to the flowerbed. I have been thinking about trying to shoot CO2 through the copper tube which will freeze up the line instantly cooling the wort. A couple of times quickly opening the valve on the CO2 and your wort should be cooled. I will try it this weekend with pics and post them on Mon.........I hope. Sorry one more thing Yes for chilling
Good luck and keep us posted.
Have you tried it with just the tube to see if you can freeze it with a shot of CO2.
Personally, I don't see it working. The drop in temp from liquid CO2 rapidly decompressing (and I mean rapid) happens in the tank, not in the tube. By the time the gas hits the tube its already a gas and no more temp drop. The gas that comes out isn't freezing in temp. The tank walls are freezer as engergy (temp) is being taken from the environment to vaporize the gas. Liquid to gas state is an increase in energy, i.e. heat.
Someone can correct me if I am wrong.
I assume by tube you actually mean a coil of copper tubing. SO you have a 10' copper immersian chiller.
Yes I do have a 10' copper immersian chiller. And your right about the gas, but I will be trying this out with a syphon tube CO2 so that liquid CO2 goes into the copper tube. Sorry about the mess up, Im a newbie at this.

Is this a method that has been recommended or seen somewhere? Sounds very dangerous, and over the top to be experimenting with, and I just do not see it working. HOWEVER, as i said earlier, I am vveeeeerrryy curious. Not knocking this, to each their own, just sounds suspect. GOOD effen LUCK!
Oh, and do you have the ability to snap a few pics of this?

Certainly, going from liquid to gas for any chemical is an endothermic reaction. That is, going from a liquid state to a gaseous state requires energy (in the form of heat) to be taken from the environment resulting in a cooling effect.

At room temp, or close to 20C (68F), CO2 is a liquid only at ~823 psi or greater. You simply cannot siphon liquid CO2 at normal atmospheric pressure. You would need a closed system similar to a freon refrigeration system to accomplish what you propose. If somehow you were able to get liquid CO2 into a 10' copper tube that instantly raised to temp to 212F (boiling) at an atmospheric pressure say at sea level, you probably wouldn't have brewery anymore and your friends and family would be picking bits of you off the next door neighbors house as the explosive force of a large volume of liquid CO2 expanding instantly to gas in an enclosed space would result in extraordinary explosive forces... In other words, don't try this at home folks!
From what I am getting from some of the people I work with. If I turn the tank upside down liquid will come out or I can use a siphon tube co2 witch just puts out liquid. We sell the liquid co2 to costumers wanting to fill paintball guns and people that want to make dry ice(side note: Dropping some dry ice in the wort directly affect anything??). So I know it will freeze up the copper tubing. my hope is that with only 10 feet to go it wont freeze up to soon and wont go through the copper all of the way. another opion is to spry the liquid on the outside of the stainless pot and freeze that. CO2 is not that dangerous if you are outside, its not flamable in fact they use that in some fire extinguishers. I my not get a chance to do this project this weekend I will try. Thanks again for your guys input I am new at this in fact I just put my first batch of IPA in the fermenter on wenday. 
......and burtblue was never heard from again.

HA! 
Hopefully, it wasn't because of this absurd experiment that we haven't heard from him...
