One of these things just isn't the same.
One of these things is not like the others.
Can you guess which one??
If you guessed the ice cream sandwich in the medicine cabinet, you would be correct. The ADD child took it from the freezer, then decided that she didn't want it right that moment, and thought that the medicine cabinet would be a great place to keep it until she did want it. THEN she forgot all about it.
Technically the cup with a penny rusting experiment next to it doesn't belong there either, so I guess I'll give credit for that one too.
