Fun with Cold

Published on 2005-06-04, by Janitha, ©Janitha.

Low tempuratues and things that cause items to drop their tempurature dramatically fascinates me, or simply process of taking away lots of heat energy from random items around is quite fun. And one of the easiest ways to do this is by letting something evaporate fast taking away heat from around it, and normal gases in the liquid state do this really well. Liquid Nitrogen is quite fun because of this, better yet the cost to fun ratio is also good, but sadly its hard to get a hold of (suppliers get real suspicious when a college students ask for some). Well not to worry, there is an alternative. Just like its hard to come by radioactive material but you can get small amounts (~5 microCuries of Americium 241) from your ordinary somoke detectors. Less than great, but better than noting.

DISCLAIMER: If you attempt to this at home, beware that this may affect your central nervous system, give you frost bites, die, get high, or a combination of these. Don't blame me if any of these happen to you.
