I clean out and freeze ice in 1/2 gallon cardboard juice cartons. I squeeze the carton before I cap it, otherwise the ice expanding splits the carton.

These cartons of ice are a convenient dimension to fill a cooler. The ice keeps longer and as they do start to melt you can pour drinking water off of individual cartons.

If you are storing food a couple of these keep the whole cooler cold.

My dad started this years ago - I don't know if he came up with it himself or if he learned it from someone.

These don't work the best for beer or other beverages - but who keeps beer on ice for a week?
