Museum of Science and Industry, Chicago

The largest science museum in the Western Hemisphere!
Housed in the only remaining building from the 1893 World’s Fair, MSI is a Chicago must-see! You’ll experience 14 acres of hands-on exhibits and have the chance to stand before a 40-foot tornado; climb aboard a World War II German submarine; take a run in a human-sized hamster wheel; navigate through a mirror maze; board a 727 hanging from the ceiling; transmit your pulse to a 13-foot, 3-D beating heart; and much more!
