Slurpee 思乐冰
A Slurpee is a slushy frozen carbonated beverage sold at 7-Eleven stores.
Machines to make frozen beverages were invented by Omar Knedlik in the late 1950s. The idea for a slushed ice drink came when Knedlik's soda fountain broke down, forcing him to put his sodas in a freezer to stay cool, which caused them to become slushy. The result was popular with customers, which gave him the idea to make a machine to help make a "slushy" from carbonated beverages. When it became popular, Knedlik hired artist Ruth E. Taylor to create a name and logo for his invention. She created the ICEE name and designed the original logo, which is used today. Early prototypes for the machine made use of an automobile air conditioning unit.
