If your mom (or dad, sibling) ever made you lunch, maybe you wondered what you were going to chow down on when you opened up your lunch box. Maybe it was usually the same (boring) stuff. Or maybe you got a surprise candy bar or soda.
Or depending on how old you are, maybe you could always tell what you were going to get -
because you could see through the plastic container!
....or maybe you never had a lunch box or plastic container and only got lunch bags.
...reaching inside you would grab at the sandwich or bag of chips, or was that a plastic bag of fruit?
