It's the Slurpee's 50th anniversary.

The beverage was invented when the soda fountain used by Omar Knedik, a Kansas hamburger stand owner, broke. He kept sodas in the freezer. He later found the slushy beverage and it became popular with customers. So he developed a machine to perfect the process.

The Slurpee name comes from the slurp sound that is made when it is consumed.
