Thursday (July 11) is National 7-Eleven Day and you know what that means? Free Slurpees!

The Slurpee first hit the scene back in 1966 when 7-Eleven modified the machine used to make the Icee. They branded their version of the drink as the Slurpee because of the sound the slushy makes as its sucked through a straw.

So, grab your free Slurpee and mix it up with us this year! Check out five ways to spike your Slurpee below.
