Cool! ..maybe not cool..(sorry)...make that kewl :) Well if that's
the case, I may as well try it. If you want really cold....but
hard to control temps...you can get a pure CO2 fire extinguisher
and blast away...I think if you blast in a cloth bag, you'll collect
dry ice in it. I could just take my radio to the local Sub-Zero
ice cream store...they blast liquid nitrogen into the mixing bowl
and you've got ice cream in 5 seconds.

As I said, temperature is not really an issue. It's only a psychological issue. ;-).

You psyched yourself out. ;-)

I picked up -100 frig for $100.
Want to do semi true cryo. pack your stuff in dry ice in a styrofoam cooler and then go to your local gas supplier ( you know acetylene helium,etc.) and buy a flask of liquid nitrogen and pour it into the cooler with dry ice, : seal with duck tape for a week
DANGER ! liquid nitrogen freezes instantly on contact and when evaporating displaces 1000 times its volume in air. Do NOT attempt except in very well ventilated rooms, and make sure you know what the hell you're ding.
