11-year old Gitanjali Rao has been honoured with 'America's top young scientist' award for making a quick and low cost test that can detect the contaminated water. She was one among the ten finalists who interacted with scientists for three months after which they developed their ideas. The invented device uses carbon nanotubes to detect lead in the contaminated water.
Gitanjali's portable invention has been named Tethys which means a Greek goddess for fresh water. Gitanjali has been awarded $25,000 prize money for her invention and she expressed that she would either turn a geneticist or an epidemiologist in future.
