Most children have so much fun here that they don't realize they're actually learning something. Creative hands-on exhibits demonstrate scientific laws, cultural diversity, and problem solving. Some of the most popular stops are also the simplest, like the bubble-making machinery and the two-story climbing maze. At the Japanese House you're invited to take off your shoes and step inside a two-story silk merchant's home from Kyoto. The "Boston Black" exhibit stimulates dialogue about ethnicity and community, and children can play at a Cape Verdean restaurant and the African Queen Beauty Salon. In the toddler PlaySpace, children under three can run free in a safe environment. There's also a full schedule of special exhibits, festivals, and performances.
