Children's Museum of Pittsburgh

Kill a day (or at least half a day) with the kids at this multistory fun house, which includes an attic space devoted to illusions, a waterplay area, a multimedia studio for young ones, "tough art" – which is art that your children can interact with to their heart's content – and a fantastic exhibit on Pittsburgh native Fred "Mister" Rogers, including the TV host's original puppets, sweater and sneakers.
