Between "Genuine danger" and "Raving Safety Paranoia" there must be some sensible middle ground. Dry ice is fun. Figure out a way to handle it safely.

Buy dry ice from suppliers listed in your yellow pages phone book for about $1 per pound. Or in Seattle, get it from QFC grocery, in the seafood section.

Dry ice lasts a couple of days when stored in a thick-wall styrofoam box with a lid. It helps if you place a couple of layers of paper bags in the box so the dry ice isn't pushing against the styrofoam. Even better is to wrap it in many layers of aluminized mylar "emergency blanket." If outdoors, keep the box out of the wind (the slightest bit of air motion will evaporate it all within hours.)
