Although its exhibits are aimed primarily at children, the Pacific Science Center is fun for all ages. The main goal of this sprawling complex at Seattle Center is to teach kids about science and to instill a desire to study it. To that end, there are life-sized robotic dinosaurs, a butterfly house and insect village (with giant robotic insects), a Tech Zone where kids can play virtual-reality soccer or play tic-tac-toe with a robot, and dozens of other fun hands-on exhibits addressing the biological sciences, physics, and chemistry. The August Bubble Festival is always a big hit. There's a planetarium for learning about the skies (plus laser shows for the fun of it), and an IMAX theater. Be sure to check the schedule for special exhibits when you're in town.
