Looking up at Chicago’s tallest skyscraper, you might wonder: “How can a building be so tall without falling over?” The Willis Tower is actually made up of nine towers “bundled” together to make it both strong and tall. Join us as we build tall and test the “bundled tube” method using LEGO® and other studio materials.
