I went to the Franklin Institute as a high school student and had a blast. For a museum, it's definitely top notch. They have an iMax theater as well as several exhibits. At the time, they had this sandbox with water spouts. My friend and I spent almost an hour building dams and making "dam" jokes. If I'm not mistaken, it was also the place Rocky ran up the steps in the movie. Be sure to check it out!
