The 'drinkable books' that are saving lives
Scientists in America have designed a drinkable book that can save lives by making polluted water safe to consume.
It's an instruction manual with information on how and why water should be filtered.
Once read, its pages can be torn out and used to turn dirty water into drinkable water.
