[CAUSE] The Drinkable Book

An interesting initiative presented here…from 
their YouTube page:

“The Drinkable Book is a life saving tool that filters
water and teaches proper sanitation & hygiene to
those in the developing world. 

Each book is printed on technologically advanced
filter paper, capable of killing deadly waterborne diseases.
Each page is coated with silver nanoparticles, whose
ions actively kill diseases like cholera, typhoid and E. coli. 

Once water is passed through the filter, bacteria
count is reduced by over 99.99%, making the filtered
water comparable to tap water in the United States
of America.

This filter paper will revolutionize water purification. It
costs only pennies to produce, making it by far the
cheapest option on the market. Each filter is capable
of giving someone up to 30 days worth of clean water,
and each book is capable of providing someone with
clean water for up to 4 years.”
