Housed in the last remaining building from the 1893 World's Fair, this is the largest science museum in the Western Hemisphere. The U-505 submarine exhibit — a real captured German U-boat — is worth the trip alone. The coal mine, the mirror maze, the full-size 727 hanging from the ceiling. It's overwhelming in the best way, and it makes you twelve years old again.
