I am sorry, Evian and San Pellegrino and Dasani and all the other bottled waters out there—Aqua Velva, Wells Fargo, Muddy Waters, Joan Rivers, Jerry Springer, whatever—but the current campaign against paying good money for bottled water when tap water is perfectly good (and very likely purer) is so sensible on the face of it that I am now done with you.
Fini. Kaput. Ausgeschlossen. No more designer water. Water is water. If you want lemon flavoring, add a slice of lemon. You want bubbles, stick a straw in it and blow.
In case your tap water flunks the tast e test, try the iStraw -- a lightweight polycarbonate straw fitted with a special membrane, which uses micro-filtration technology to clean your water. If you've tried chlorine tablets, you know how icky the taste can be, and with the iStraw there's no aftertaste.
