It doesn’t take much to make my kids happy. My oldest woke me up at 6 am dressed and ready to go to the Franklin Institute in Philadelphia. We were all excited to go see “The Science of Pixar” exhibit. We spent a lot of time reading and playing with all the gadgets in the show but the exhibit that really got the kids worked up was being able to run through the model of the Giant Heart. They had me dizzy just watching them go in and out, in and out. I have to admit it was fun seeing them enjoy such a simple activity.
