Pacific Science Center

Pacific Science Center is at 200 2nd Ave. N. adjacent to the Seattle Center grounds. Exhibits run the gamut here, from a Tropical Butterfly House and Insect Village to Professor Wellbody's Academy of Health & Wellness, where interactive inventions, gadgets and experiences promote exercise, diet and hygiene choices to help ensure lifelong health. Scale-model dinosaurs are set in a Mesozoic-era environment. Other highlights include an interactive planetarium, laser light shows and two IMAX theaters with 3-D capability.

Water Works is an outdoor exhibit with pumps, a propeller and a giant water wheel. The High Rail Bicycle teaches riders about the center of mass while taking them on a daring adventure via a rail 1 inch wide and 15 feet above the ground.
