My lab experiments leave me with about a kilogram of dry ice left over every day, and it just evaporates overnight in the freezer. Seems a downright shame to waste all that potential fun... what are the most entertaining, novel uses for dry ice that you can think of?

4thOfJulyFilter: I want to be a superhero and bust out some ice cream bars during our 4th of July car camping trip this weekend. If I pack them in dry ice in a cooler on Friday night, will the dry ice last til Sunday afternoon and will it be cold enough to keep the ice cream frozen? (It'll be in the mid 80's at the hottest where I'm going.) Is it OK if the cooler is a cheap styrofoam one (since my good cooler will be filled with beer and BBQ fodder)? Is there a better way I could be attempting this?
