Bright Idea?

Whose bright idea was it to make cups for kids that have a ring of clear liquid around the glass so it looks like there is water in it? They usually put little plastic toys in between the two layers of plastic so they float in the pretend water too. This makes it very difficult to determine if there is actually any real water in the glass and how much. Not such a good idea. Although, I guess I was the bright one who did buy the cup.
