Another must see in St. Paul. Great way for the whole family to learn all kinds of things. There is the 3-D cinema and the that are great. Just remember to keep your glasses on at the 3D theater . There is so much for the kids to see and learn. The musical stairs were quite a surprise. I didn't realize the stairs we were walking on did that. Very cool to bring the whole family to, young and old. There is alot to learn even for the older generation. The kids loved exploring the different stations and learning how things actually work. To see that for themselves is something they won't forget.
