There are ways to do this right.
Buy a pint of milk.
Take a couple of big slugs.
Add cereal directly to the carton.
Pinch carton closed and shake vigorously.
Reopen carton and enjoy your portable breakfast.
Note: Be sure to use a cereal that floats on the milk a bit, and does not need supplemenart sugar. Do NOT try this with shredded wheat.
C’mon, you know they still sell the 8 packs of cereal that you open along the side, and pour milk directly into the cereal package itself.
