This is one of the largest children's museums in the world, with interactive exhibits covering everything from archaeology to world cultures to biotechnology, plus extensive toy displays, a working antique carousel, and a planetarium. It may be most famous for its Dinosphere, a multisensory exhibit that combines serious science with kid-friendly interactive exhibits, and Fireworks of Glass, a 43-foot-tall blown-glass sculpture by Dale Chihuly. In summer, its indoor/outdoor sports experience—which allows families to learn and practice golf, baseball, basketball, hockey, soccer, tennis, and even drag racing skills—is a huge hit. If you have kids, this is the place to take them.
