Water safety

 There was an organisation called SODIS which came round our village teaching people how to treat water. people in the village were very happy about this. 
They came up with a very good solution which has helped many people who doesn't have money to buy waterguard. they were given some bottle with bottle top. if you want  to use you put water in the bottle then you put on the iron sheet, then the solar which is the sun it heats the water then it kills the bacteria in the water. When there is sun and cloud you heat the water for two days.
