Free Slurpees at 7-Eleven on 7/11

Brain freeze alert: Stop by 7-Eleven on Saturday, July 11 (7/11) for a free Slurpee to celebrate the chain's 82nd birthday. The free 7.11 oz drinks will be available between 7 a.m and 11 p.m.

Via Lifehacker.com, here are some Slurpee facts:
* Slurpee drinks are all served at 28 degrees.
* Slurpee was "invented" when some sodas were put in a freezer to cool them down -- and they became all slushy.
* Winnipeg, Canada is generally thought to be the Slurpee capital of the world, due to their amazing Slurpee fanaticism.

And while Detroit was third place city for Slurpee sales, for the 10th consecutive year, Manitoba, Canada has been named as the world's leading market of Slurpee drinks.

"I have one of these big ones a day, and sometimes two," said Curtis Kopeschny, a self-described "Slurpaholic," in an interview with Winnipeg Sun.
