‘Drinkable Book’ Promises to Filter Dirty Water

A new invention promises to make dirty drinking water potable by filtering it through the pages of a book.

The “drinkable book,” which was presented Monday at the American Chemical Society’s 250th national meeting in Boston, consists of pages that are treated with silver or copper and printed with instructions for how to use them: tear out a page, insert it in a filter holder and pour unclean water through it.
