In the late 1950s, Omar Knedlik's soda fountain at his restaurant broke. He stashed some soda pop in the freezer and had the idea to turn frozen soda into a beverage. He used parts from an automobile air conditioner to build a simple frozen beverage machine. Since then, Slurpee has become a beloved beverage of millions, a pop culture icon, and 7-Eleven's most well-known proprietary brand. From its beginning, with kooky flavor names like Fulla Bulla, Blue Blunder and Awa Awa Ukulele, Slurpee® has been keeping it "cool" for generations.
