A must-see for kids of any age is this tantalizing collection of interactive exhibits and rides designed to provoke the imagination and teach scientific principles. The Virtual Zone includes Comet Impact, a motion simulator ride that rockets you into the heart of a comet, and other virtual-reality attractions with a scientific bent. The Fleet also houses a 76-foot-high IMAX Dome Theater (the world's first) showing films so realistic that ocean footage can actually give you motion sickness. Every Friday evening, four different IMAX films are shown in succession. The Fleet also has a spiffy planetarium simulator powered by computer graphics. Planetarium shows are the first Wednesday of each month at 7pm ($8.50 adults, $7 seniors and kids 3-12).
