They are at the Minnesota Children's Museum.
What an awesome place for kids. I so wish we had something like this.
This particular room was set up like a forest. The floor was the forest floor, and there were trees everywhere for hiding and playing in. A great little stream was in the corner. The stream had play fish, frogs and tadpoles among others all for water play. In the same room upstairs were cranks. You could move the clouds around. If you got them set up the right way the room would get darker and it would thunder and lightning. So cool!! And this was just one room!
