Changing the World: Swaziland´s Kids

Two teenagers from the southern African country of Swaziland have won Scientific American's inaugural Science in Action Award, part of the Google Science Fair

The prize is awarded to a project that addresses a social, environmental or health issue to make a practical difference in the lives of a group or community. 

This year's winners are both 14 years : Sakhiwe Shongwe of Siteki and Bonkhe Mahlalela of Simunye.

Their project explores an affordable way to provide hydroponics to poor subsistence farmers, enabling them to grow their crops and vegetables in very large quantities and within limited space without using soil.
