i use dry ice to chill my wort all the time. i use a slightly different method than you do but it works. i get a small tub of water thats big enough to set the brew pot in. fill it part way with ice water. when brewing is done and your ready to cool i drop the dry ice in the tub of ice water then put the pot in on top of that. then hook up my wort chiller and let it do its thing. the dry ice keeps the water in the tub cold and seems to make the cooling much faster than just a wort chiller alone.

Haha, we're both right, you had me doubting myself for a second, but either is correct per http://en.wiktionary.org/wiki/sublime.

But o well it was fun and i decided to grab a thief and fill a small water bottle with some beer from a beer that is secondarying and carb it tasted pretty good also filled a couple bottles with a bit of water and dry ice and shoot them with a 1860 New Army 44 Cal Revolver BP

I got one of them! It's a cheap kit gun with a brass frame. Haven't shot it in years.

Yep, so as cold as the ice was (barely colder than sublimation temp), you didn't cool your wort down because the wort raised it to sublimation, and then you just had a cloud of cold CO2 above the wort which wasn't doing anything to cool the wort down. Ever notice how when someone puts dry ice into colored water for that mad scientist effect how the water somehow never freezes?

Dry ice can be dangerous if ingested. I was reading a website on dry ice and it recommends against that. Could you imagine if you drank dry ice. I was just reading an article about an MA kid that did it. What are the advantages to keeping drinks cold with dry ice?

THe only way dry ice is dangerous is if you eat the solid stuff, and it's only dangerous because it's very cold and expands a lot as it sublimes to a gas. Dry ice is just solid CO2, you drink CO2 in every beer you down...
