The Carnegie science Center, located in Pittsburgh, PA, is a wonderful, interactive learning center great for all ages. For a minimal amount of money to get in, you and your kids can spend all day here looking around at the various displays. Four floors hold hundreds of different displays and creations, all designed to get you playing and learning. Exploration Centers, an aquarium, a huge train set, and so many hands-on activities are littered throughout the building. Catch a show at the Omnimax and watch the domed screen with over a hundred speakers playing for a spectacular show. Theres a real-life submarine to walk through outside-see what is was like to live in such cramped, underwater quarters! Kids and adults love the science Center, i know my kids and I certainly do! A must if you are in the area of Pittsburgh.
