Unlike many other items, potatoes do not actually need to be refrigerated, and, in fact, they will fare better outside the cool environment of your fridge. Storing potatoes properly will ensure you get the maximum shelf life out of the starchy, versatile vegetable.

Honey. Honey's many magical qualities make it an incredible preservative — ancient cultures didn't use it to embalm dead bodies for nothing! Honey can last forever, it doesn't need to be refrigerated.
Apples do best in an environment with 90% humidity. Did you know that your refrigerator is a natural dehydrator?
