Many students skip the last few days of school, but Dorothy loves those days. The teachers clean out their classrooms and she comes home with all sorts of stuff -- tshirts, 6th grade math workbooks, scrap papers, and on and on. Today, the science teacher gave her a boxed kit of science experiments. Dorothy opened it in the car. "Oh great!" she exclaimed. "You know it's gonna be good with it says 'Do Not Eat' on every package!"
