End your 7/11/07 with a free 7.11 oz Slurpee today! All day 7-Eleven has been handing out the free frozen drink in celebration of their birthday. A little nutritional fact about the drink: "Slurpees are mostly water ice and are heavily infused with air; there is less food energy in a Slurpee than in the same volume of a soda.They are also generally considered kosher 'parve', as well as halal." Here are some Slurpee tips and recipes. Just beware the dreaded brain freeze!

Of course, if you go to the 7-Eleven Kwik-E-Mart in Times Square...you'll have to order a Squishee instead, but it's still free!
