Usually water is purified using water purifiers and with other available methods. But, have you ever heard of cleaning water with Corn Cobs? Yes, this new method was discovered by a teenage girl at Odisha.

This was developed by the 13-year-old student from Odisha who has won the Community Impact Award at Google Science Fair in 13-15 years category.

Sripada Srisai Lalita Prasida, who studies in 9th standard at DPS Damanjodi in Odisha’s Koratpur district, has invented the new system of purifying water.

Prasida has been awarded $10,000 as prize money; Google will build the project further. Corn Cobs is used in order to purify water from domestic as well as industrial wastes by applying the principle of absorption.

Prasida observed that corn cobs have a facility of absorbing the contaminants like salt oxides, detergent, suspended particles, coloured dyes, oil, grease and even some heavy metals.

Her facebook page says that, corn cobs will absorb 70-80% of contaminants; it is also used to clean water bodies like ponds, tanks and rivers.
