This noisy hall of wonders and widgets is one of Chicago's most popular attractions. Dedicated to presenting science, industry and technology in an entertaining way, the museum's hands-on displays invite visitors to push, pull, compute and enjoy exploring topics in six zones: the human body, transportation, communication, manufacturing, energy/environment, and space/defense. You can take a simulated flight, tour a submarine, take in a 3-D movie or explore the Idea Factory (geared toward youngsters) as well.
