Created for McDonald's Operators of Chicagoland and Northwest Indiana (MOCNI), the The Leo Burnett McDonald's Shamrock Shake cruised up and down the Chicago River as thousands of spectators watched the 12-foot cup, tipped on its side with [minty green shake material](https://www.trendhunter.com/trends/jacks-lucky-mint-trio) pouring out, giving the impression that it was dyeing the river. A [giant, domed lid](https://www.trendhunter.com/trends/colorchanging-cold-cups) (measuring in at 4 feet x 8 feet) and straw (8 feet) sat alongside the cup on top of a 192-square-foot deck (24 feet x 8 feet). The lid, straw and cup--complete with a cherry and whipped cream--weighed an incredible 1,000 pounds. The Leo Burnett McDonald's Shamrock Shake's journey between the Columbus and Wabash Avenue bridges lasted for approximately 1 hour.
