Hammacher Schlemmer has taken it upon themselves to do something about that extra cylinder of compressed liquid CO2 we all keep in our closets. Rather than keep it on hand in case of an emergency that only liquid CO2 could solve, let's all throw caution to the wind and make some dry ice with the . . . *drum roll* . . .
