Neat drinking water trick
Ross mentioned freezing water in jugs, which prompted me pass this on: (I know nobody in this crowd would ever drink wine from a box, but if you know some low-life that does, ask him for the empties.) Cut a small hole in the top of the liner bag, and fill with water or other freezable beverage, replace in box, and freeze. Remove and discard box, place as many as practicable in ice box or cooler where they serve as ice while waiting to be drank.
