First there was a billboard that purified polluted air. Now, there's a book that makes water clean and safe for human consumption. DDB New York and WATERisLIFE launched "The Drinkable Book" that not only educates people about water sanitation, its pages can be torn out and used as filters to make otherwise filthy water safe to drink. "The Drinkable Book" is made from a new type of paper invented by McGill University & University of Virginia chemist Dr. Theresa Dankovich that works like a coffee filter. Each page of the book is coated with silver nanoparticles, which kill diseases like cholera, E. coli and typhoid. Once water passes through a filter, bacteria is reduced to a level comparable to our own drinking water. The educational content on each page is printed in food-grade ink in both English and Swahili. Each book contains 24 pages, with two filters per page. The books cost pennies to produce and a single book can provide a person with clean water for four years. Check out a video of how it works here.
