The solarball is a water purification device. It consists of a clear plastic sphere which the user would fill with water and then wear on their head. A solarball can produce 3 liters of clean water per day. Sunlight enters inside of the ball passing through transparent layer and evaporates dirty water, in the other side of the ball water vapours get condensed and form clean water. It was invented by Jonathan Liow, an Australian student who is studying Industrial Design.
