If you’re a fan of sparkling water but feel guilty about having to buy it bottled, you might enjoy this NYT story about home seltzer makers that provide "environmentally conscious effervescence."

Myself, I don’t care for the bubbly stuff, but I did find this part amusing (emph. mine, obvi):

Plain tap water has become the surprise food fashion of the year. A growing number of restaurants are offering it in place of bottled water, which is much more lucrative and whose popularity had made the free-flowing kind seem déclassé. On the street, it is not uncommon to see people toting tap water in refillable Nalgene containers.
