Boxes of spaghetti, once opened, are a pain. They're not air-tight, they never seem to stay closed, and spilled dry spaghetti is hard to pick up off the floor. Once you open that box of spaghetti (or fettuccine, linguine, etc.) use a cleaned-out Pringles can to store it. It seals it up and keeps the spaghetti safe and unbroken for the next use.
