Amazement Square: The Rightmire Children's Museum

If you find yourself downtown near Ninth and Jefferson, keep your eyes peeled for the giant ant that marks the entrance to Rightmire Children's Museum, a four-level structure known more popularly as Amazement Square. The family-friendly learning center offers a ton of hands-on fun, including the nation's highest indoor climbing tower, a "walk-through" model of the human heart, and exhibits that explore the secrets of gravity, inertia, and velocity.
