For the NCAA Men’s Final Four competition, Coca Cola and Ogilvy & Mather have imagined a “drinkable billboard” : it’s an ad billboard installed at the White River State Park in Indianapolis that gives Coca Cola Zero for free to passer-by, through a massive straw. Like a public fountain, this installation features 6 straws, 16 captors and 75 valves to bring the soda to people.
