The solarball is water purifier which consists of a ball-shaped structure where the dirty water is stored. The dirty water evaporates due to sunlight and the clean water floats to the top of the dome of the solar ball. The process continues all day around, and the tiny evaporated clean water is slowly collected for drinking purpose.
