This is incredible. It's called The Drinkable Book - a life saving tool that filters water and teaches proper sanitation and hygiene to those in the developing world. Each book is printed on technologically advanced filter paper with ions that can actively kill diseases like cholera, typhoid and E. coli while at the same time reduce bacteria by over 99.99%. Best of all, each filter (or page) is capable of giving someone up to 30 days worth of clean water. Each book is capable of providing someone with clean water for up to 4 years. How's that for a life-changing idea? More like this please.
