The humanitarian group WaterisLife and ad agency DDB have teamed up to promote and distribute a product called The Drinkable Book. Based on the research of Teri Dankovich, The Drinkable Book features information about water-use safety and hygiene, and is printed on detachable pages coated with silver nanoparticles that attract bacteria, allowing each page to serve as a filter that leaves water 99.9% pure. Each page lasts for about a month, meaning the entire book will filter four years' worth of water. The Drinkable Book is currently being printed in English and Swahili and distributed in Kenya, but the producers are hoping to expand their operations in the near future. In a world where over three million people die each year of water-borne diseases, this (comparatively) cheap and effective water-purification system is incredible news.
