Until now, Sonic Diet Coke has been my definition of Perfection; great mix, pellet ice in a (admittedly, non eco-friendly) foam cup. Until, that is, I was introduced to the new Metal Slurpee Straws by my sister (and fellow DC addict/enabler). The combo must be experienced, so wait no longer. Run, don't walk (or in this heat, you may want to drive) to your nearest 7-11 and procure one (or several) for yourself and everyone you know. You'll thank me. And yes, it's THAT big of a deal.
