"A visit to see the cool tiny stuff (lots of books) at Michael's Museum in the Children's Museum of Chicago."
In turn I highly recommend her book "The Sixty-Eight Rooms." I loved it. (Sixth-graders Ruthie and her best friend, Jack, are on a class visit to Chicago’s Art Institute, where they see the famous Thorne Rooms. Filled with incredible miniatures, the rooms, representing different time periods, fascinate Ruthie. When she finds a key that shrinks her and allows her to get inside the rooms, Ruthie wants to return as soon as possible. Jack is a willing partner, and when a way is found to shrink him, too, the adventure really begins.)
