Hundreds of hands-on exhibits draw families to this interactive science museum, which also has an Omnimax theater and the Northwest's largest planetarium. The many permanent and touring exhibits are loaded with enough hands-on play for kids to fill a whole day exploring robotics, ecology, rockets, computers, animation, and outer space. Moored in the Willamette as part of the museum is a 240-foot submarine, the USS Blueback, which can be toured for an extra charge.
