A glass of water

Drinkable water is a rare commodity for millions of people around the world

美國的研究人員設計了一本教人們如何通過過濾方式獲取飲用水的說明書。而這本書的每一頁紙都可以被撕下來充當濾紙。BBC Jonathan Webb有以下報到:

More than 600 million people around the world lack access to clean drinking water and this book has the potential to help.

It's relatively cheap, easy to ship and its pages serve two purposes: firstly, they are printed with instructions on how and why water should be filtered; secondly, they can be torn out and used as filters.

The paper contains nanoparticles of copper or silver, which kill bacteria and the new trial results from water sources in South Africa, Ghana and Bangladesh confirm that on average the paper slashes the bacteria count of contaminated water by well over 99%.
