When I want to cool a solution I drop in one or two of these and stirr for a while. Works great as long as you don't get all excited, stirr too fast, and dislodge the pop-off lid. Mark them for developer, fixer, etc. Adam On 12/1/05, Jeffery Smith <jsmith342@cox.net> wrote: > I'm not sure where Feli is but, down here in the subtropics, the big > challenge is finding water that is cold enough to use.
