Get an empty, clean cereal box. Cut a white piece of cardboard that will fit snuggly in the bottom of the box, or secure it permanently by gluing it in place. Cut the top of the cereal box, removing both ends and leaving the center intact. Put a piece of tape across the center of the top to securely hold it closed.
