McDonald's Shamrock Shake Helps Chicago River Turn Green
If you've been to Chicago, you've seen the Chicago River which winds through the city. There's bridges, tour boats and lots of scenic views. And the water gets turned green each year for St. Patrick's day. This year, Leo Burnett added a twist by placing a giant plastic McDonald's Shamrock Shake cup alongside the river. The installation made it appear as if the contents of the cup had spilled into the river.
