This `drinkable book` could save thousands of lives around the world

Water purification systems have advanced a lot in recent years, and now one team of scientists and designers have come up with those most elegant and accessible way of implementing them yet: a drinkable book.

By infusing a thick piece of paper with anti-microbial silver nanoparticles, Dr. Theresa Dankovich. of McGill University was able to make reducing the bacteria in water by more than 99.9% as simple as tearing a page out of a book and using it as a filter.

The book also educates as it purifies, being printed with food-grade ink containing instructions on how to use the paper properly and how to better avoid contaminated water.
