A little trick: I was watching the kids at the mall while my wife was shopping. We were sitting on a bench waiting for her to return. They were getting restless. While they weren't looking, I threw a penny and dime on the floor next to a fountain and told them, "Look - there's money on the floor over there - maybe there's more!" They grabbed it up and searched and searched for more. When they started getting tired of looking, I threw some more coins under a bench for them to find to keep their interest up. A cheap way to keep them entertained until my wife returned. Just gotta outsmart them rascals!
