Things this world does not need

Water sommeliers:

In Tokyo and Paris, you can now spend $5 a glass on special beverages selected by a professional sommelier.

Nothing surprising there, except the beverages being served are different brands of bottled water — with various “flavors” supposedly matched to different foods.

Desalinated seawater from Hawaii, meanwhile, is being sold as “concentrated water” — at $33.50 for a two-ounce bottle. Like any concentrated beverage, it is supposed to be diluted before drinking, except that in this case, that means adding water to . . . water.

Oh, and the only thing that is “concentrated water” is ice located in the minds of water marketers. (Enough with the science e-mails! You’ve convinced me!)
