People usually think of books as the homes of good stories or sources of information — or in the worst-case scenario, a killer of trees. Still, they’ve been an invaluable resource for ages, and that won’t change anytime soon. That’s going to be especially true if certain plans come to pass — namely, that there’s a “drinkable book” eager to hit the market.

The product is the brainchild of Dr. Theresa Dankovich, who came up with the idea for her chemistry PhD. It’s worth noting upfront that the book itself isn’t drinkable, but instead works as a filter that creates drinkable water; its pages are imbued with tiny particles of silver, which in turn eliminate the microbes that contaminate dirty water. It’s a strange idea, but given that prototypes have already created clean water in twenty-five separate areas, the technology clearly works.

Notably, The Drinkable Book can last for roughly a year as a working filter — and true to its nature, has plenty of information about the importance of clean water as well as methods to obtain more. Granted the book isn’t on the market yet, as it’s still in development and the crowdfunding phase. Whatever the case, any invention that aims to give clean water to those that need it deserves more than a little praise.
