I took the kids I nanny (ages 4 and 2) there today and they had such a fun time! It was interactive and at times and generally interesting that we spent almost three hours there. They also had a little play station in one of their exhibits which they enjoyed so much that we spent a good portion of our time playing there. My only issue was that some of the staff there were slightly rude when I asked some clarification questions which I'm assuming was due to it being Friday but it won't stop me from coming back another time!
