THE IDEA: You know how the tops of cereal boxes can get mangled, especially if you have little kids (or an impatient S.O.) who are always tearing into the box, or forgetting to clip it closed? This hack solves that. To self-seal, pop three out of the four flaps into the cereal box, and fold the skinny sides so that they point inside. Tuck the last flap around the folds so that it is flush with the opposite flap.
DID IT WORK: Absolutely!
