The 7-Eleven Slurpee is quite possibly the best frozen treat on the planet.
Because the drink is so unwaveringly popular, 7-Eleven has a few days out of the year it uses to remind the world that Slurpees are the ultimate frozen treat.
On July 11th, or 7-11, it rewards fans with a free Slurpee just for walking through the door (and usually waiting in a line).
And once a year, 7-Eleven lets you bring whatever vessel you choose to fill your own cup with Slurpee.
For some inspiration before you hit the Slurpee nozzles, here are some of our favorite containers from years past.
