CHICAGO (AP) — Chicago's Museum of Science and Industry is celebrating its 80th birthday.
The facility on the city's South Side is opening a new exhibit Wednesday to mark the occasion.
Curators say the "80 at 80" exhibit will feature a collection of dozens of rarely displayed artifacts from the museum's vast collection. They include a giant Paul Bunyan statue and a 1909 version of GPS.
The exhibit will run through February 2.
MSI opened its doors on June 19, 1933 and was the first museum in North America to feature interactive exhibits. Last year, more than 1.4 million people visited the museum.
