The goal was to create a fun, attention-getting ambient experience on the streets of Chicago for Windex. At the same time,Draftfcb Chicago wanted to prove in a light-hearted way what so many Windex users have learned: 'Glass is so clean it's invisible'. The solution was a guerilla effort utilizing Chicago's renowned Second City improvisational performers and … Nothing. The result: thousands of consumers saw nothing and went away thinking only one thing: Glass so clean it’s invisible. This event was staged over a week during the busiest times of day on Chicago's Michigan.
