Chicago's Museum of Science and Industry is one of the largest science museums in the world. It is home to more than 35,000 artifacts and nearly 14 acres of hands-on exhibits designed to spark scientific inquiry and creativity.
It has great exhibits, including numerous planes hanging from the ceiling, the captured World War II German Submarine U 505, Spacecraft, a working coal mine, a giant model railroad, and numerous other attractions.
The building is the only remaing structure from the World's Columbian Exposition of 1893. In the course of its six-month run, that remarkable World's Fair drew 27 million visitors to Jackson Park. Attendees sampled new foods (including Cracker Jack and Pabst Blue Ribbon beer), marveled at new technologies (including the zipper), and listened to music transmitted live via telephone from New York all while surrounded by a "White City" of buildings envisioned by Chicago's architectural legend Daniel Burnham.
