“Christmas Around the World”
Time Out says
Every year, the Museum of Science and Industry puts up its 45-foot-tall Grand Tree and surrounds the towering pine with more than 50 trees that represent Chicago's various communities and their respective holiday celebrations. Visitors can admire the 30,000 lights that cover the trees and stick around for the "snow" that falls from the rotunda every 30 minutes. During the weekend, live performances of holiday music fill the room, lending some additional seasonal cheer to your day at the museum.
