text: is there a way to make home made dry ice.? i know it's not halloween yet.but i would like to plan ahead.i love to have outdoor partys for my favorite time of year.dry ice would spruce things up a little.any ideas the rag thing may work.  co2 is available at any welding supply store like praxair.  small parts has a really cool plastic box kit with tubing and everything.  i bet you don't want to spend 300 bux, but i'm sure you may find one cheaper or can rip off the design of the one in the website.
