This is a great place to take the family. Went on a field trip with 4th graders and had so much fun. The exhibits were awesome. The best was the tornado house. You sit in a "basement" and hear the storm outside and the radio with the weather updates, see a tree fall in front of the window, feel the thunder. Great experience for the kids.There are about 10-15 exhibits with some that are rotating. It is definitely a must see when visiting the St. Paul area. Also, it is within walking distance to the capital. This is a great way for the whole family to learn about the history of Minnesota.
