"Hands-On Science for Kids Another one of the buildings created for the 1962 Seattle World’s Fair, the Pacific Science Center has a midcentury-space-age vintage-futuristic look from the outside. But inside, it’s all cutting-edge technology like the IMAX Theatre, laser dome and planetarium, and Live Science Stage demonstrations. The 4,000-square-foot tropical butterfly house is a favorite with visitors of all ages; we know of at least one wedding proposal that took place there. The dinosaur exhibit features seven animatronic, roaring dinos, while Professor Wellbody's Academy of Health & Wellness is a kid-oriented tour of the human body, complete with gross-out fun facts. The Insect Village has plenty of creepy crawlies, and the saltwater tidepool exhibit features sea creatures that kids can touch. Outside, the Science Playground has gyroscopes, bicycle-powered fountains, and other hands-on fun. The Pacific Science Center also tends to get the high-profile touring exhibitions, like the 2012 Tutankhamen exhibit, so it’s worth checking in advance and booking tickets early if you plan a visit."
