Museum of Science and Industry, Chicago

See your heartbeat 13-feet tall, climb aboard a World War II German submarine, take a tour of your digestive system, plunge into a working coal mine or control a 40-foot tornado. Journey through a mathematical mirror maze. Plunge into a working coal mine. Step into the future. Those experiences and more await you at the Museum of Science and Industry, Chicago - the largest science museum in the Western Hemisphere and home to thousands of exhibits, artifacts and "wow" moments that last a lifetime. Naturally there is a transportation section, featuring among others the Spirit of America LSR racing car.
