Today is beloved chain store 7-Eleven's self-appointed birthday (7/11, get it?), and they're celebrating in style - with free 7.11 ounce Slurpees while supplies last!

"This year we expect to give away 7 million Slurpee drinks, more than ever before, beating last year's offer by 2 million," 7-Eleven president and CEO Joe DePinto commented on the company's website. In the spirit of the day, here are a few fascinating Slurpee facts to impress your friends:

• Every year, enough Slurpees are sold to fill 12 Olympic-sized swimming pools.

• The original prototype for the Slurpee machine included an automobile air conditioning unit.

• Only one private individual owns a bona fide Slurpee machine, the rest are in 7-Elevens. If you know who this one lucky individual is, leave a comment below because we're curious!

Diehard Slurpee fans and 7-Eleven-loving fashionistas will be delighted to know the company has also reportedly provided downloadable birthday attire including party hats, hair accessories, and miniature bowties, available online. Whether you're a more traditional fan of Cherry or Coca Cola, or you go for the crazy flavors like Peach Dragon Fruit or Wicked Apple, you better hurry because the promotion ends at 7pm. Here's a 7-Eleven store locator to help you out.
