4. The water bottle tip
Fill a bottle halfway with water and freeze so the ice is on the bottom, then lay the bottle on its side. The ice will stay in the same formation as long as the freezer keeps working. Hint: You can do the same with ice cream. Eat half, and then lay the tub on its side. Yum!
5. The trash bag cleanup
This one is especially good if you are expecting power outages. Put all the food in your freezer into a few trash bags, and put it all back into the freezer. If it stays frozen, then all is fine, but if power is lost and your food does spoil, the cleanup will be as simple as pulling the bags from the freezer and disposing of them.
Simple tips can save you so much trouble later, from gauging whether the food in your freezer is safe to eat to making cleanup a snap. Which one will you use?
