Indian-origin South African girl Kiara Nirghin on 1 October
2016 won the Google Science Fair prize 2016. She won this grand prize of 50000 US dollars' scholarship for using orange peel to
develop a cheaper super-absorbent material that helps soil retain water. Her No More Thirsty Cropsproject aimed at tackling the severe drought plaguing
South Africa. Her solution to the
problem of drought uses orange and avocado fruit peel, which are normally discarded. The fruit peel serves perfect alternative to super-absorbent polymers (SAPs),which absorb and carry about 300 times their weight in
liquid relative to their own mass.The Google Science Fair is a programme for budding scientists
between the ages of 13 to 18, who are invited to solve the world's biggest challenges using science and technology.
