In the late 1950s, Omar Knedliks’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® drinks have become a beloved beverage of millions, a pop culture icon, and 7-Eleven’s most well-known proprietary brand. 2026 marks 60 years of cheers. So, raise a cup. Here's to many more to come.
