July 11 means free Slurpees at 7-Eleven stores across the state

HONOLULU (HawaiiNewsNow) - July 11 is 7-11. To celebrate, 7-Eleven stores across the state will be giving out free Slurpees to customers.

The giveaway happens annually. Head to any 7-Eleven location between 11 a.m. 7 p.m. on Wednesday to get a free Slurpee.

Customers can get a small sized cup of any flavor. And there's apparently a limited-edition flavor currently out: Cap'n Crunch Berries.

There's a limit of one free Slurpee per person so drink up and enjoy those brain freezes while they last.

For some fun historical background, the Slurpee was created by accident in the late 1950s by Omar Knedlik of Kansas City.

According to this article, Knedlik owned a Dairy Queen. One day, one of his machines broke down. To improvise for cool drinks, he stored sodas in the freezer. Long story short, customers loved the slushy concoctions and Knedlik made a machine to recreate the semi-frozen soda on command.

After holding a naming contest for the treat, the name ICEE won and he coined the term. Until, in 1965, 7-Eleven bought the ICEE making machines, licensed it and re-branded the drink as a 'Slurpee' in honor of the sound it made while being sipped through a straw.

The rest is history.
