I read an interesting article on this bottled water over on NOTCOT. (Click here for a link to the full article.)
It's a new product in the category of children's beverages. Unlike a lot of sugar-filled drinks, Y Water is water filled with vitamins and minerals. The ingredients are certified organic, the bottles are 100% recyclable, and even the web site is "green hosted" with 100% solar energy. The best part is that the bottles themselves can be used by kids for creative construction projects.
The bottles were designed by industrial designer Yves Behar, of Fuse Project.
