Chad don't do it. Like Taylor said it makes things uber brittle. What you can do with dry ice...take a 2 liter bottle fill it about 1/2 way with water and put a small piece of dry ice...I mean like 1"-2" long and big enough to fit in the opening in the bottle...and drop it in the bottle, screw the cap on tight and step back. They make for a pretty good bang.
You think that's bad?????? Try coming to AZ where the outside air during the summer is over 110 just about every day and even gets as high as 120. Add that to your underhood temps and you get temps of like 160's-180's.

. Driving in am Arizona summer blows man.
