secret ingredients

The prevalence of water bottles lately strikes me. Especially Nalgene bottles. Most everyone owns one, and at least half of everyone seems to carry it everywhere. Its kind of weird because it seems that just within the past couple of years, water has become especially important. People are becoming more and more creative with the ways they carry their water; camel-packs, colored Nalgene bottles in all different sizes and shapes, metal water containers, and, well, recycled Aquafina, Dasani, True, etc. bottles. (Which, I should remind you, are not meant for multiple uses. -Therefore, after the first use, the plastic lining begins fallling apart and you end up consuming bits of plastic.)

Very recently, Aquafina and Dasani have come out with flavored water. To my knowledge, you can purchase, "lemon-lime," "berry," and well, that's all I can remember. But anyway, its basically just sparkling water with a fake, fruit flavor. Cool? Yeah, I suppose. I've had it a couple times, and its not bad. But the thing that gets me, is how it has 0 calories, 0 fat, 0 sodium, 0 everything! And to top it off, for the ingredients, it just reads:
Sparkling water, Natural flavors

Not too helpful. So if anyone figures out how they do that, I'd be interested in knowing. Until then, I will sip in confusion.
