The document describes an activity where teams have 15 minutes to build a tower out of balloons, tape, and other materials. They then reflect on their process and improvements for 5 minutes. Teams rebuild the tower and present what they learned. The goal is to build the highest, most stable tower that is pleasing to look at, follows a color theme, and can withstand blows without wobbling for gems and points. Key features include balloons blown per minute, defects, refactoring, and test cases.
