This is what happens in many poor countries. In Kuwait, we have clean water to drink and cook with. But it is very expensive. Fortunately, some scientists have invented something so that people in poor countries can always drink clean water. It is called a lifestraw. It is used to purify water. It is made of plastic and is cheap to buy. Inside the straw are chemicals to stop the bacteria from getting into your mouth. You can use the straw to drink any water, for example, from rivers and lakes. Simply put the bottom of the LifeStraw into any source (except seawater) and drink. The LifeStraw is very easy to clean. It could save a lot of lives.
