Contraband White Powders

Have you ever noticed that corn starch and baking powder look exactly the same? They are the same shade of white and the same consistency. So when a mother walks into the pantry to find that her two-year-old has learned how to pry off the plastic lids and pour some of the contents of one can into the other can, one has no way to see how much of the powders were mixed and whether either of the cans is salvageable.

Note to self: Add to grocery list (1) can corn starch and (1) can baking powder.
