Ok, so what's up with this? You grab a bottle of "water", you know, that expensive stuff that you can get out of your faucet. It says, "100% Natural", "Non-carbonated", etc. But when you unscrew the cap, it makes that "fssst" sound, the same you get from a plastic bottle of soda. If it's non-carbonated and supposed to be just simply water, then why does it make that sound? I'm sure there's a good reason - and if so, please tell me in the comments! I just don't get it...
