To keep your countertop cool when rolling out pastry or cookies or when making candy.  Chill it with homemade icepacks.  Make the packs out of gallon-size freezer bags filled halfway with water.  Force out as much air as possible, seal them, and place them in the freezer on a flat surface (a cookie sheet works well), so you can stack them and saves space.  They also make good ice packs for picnics.
