I don't know where the list is, but I think you can search the archives at <http://www.mail-archive.com/science%40lists.csi.cps.k12.il.us/>. There's a big dry ice plant in the south loop, kind of near the corner of 18th and Canal. I don't remember the name, but I found it by searching through the yellow pages. They're open 24 hours, and will give you a 20 pound block of dry ice (more than you'll need) for ten bucks or so. -ML -- This is the CPS Science Teacher List.
