Indian-American Gitanjali Rao has won the 2017 Discovery Education 3M Young Scientist Challenge for her prototype water lead contamination detector 'Tethys'. The sensor-based device detects the quality of water and shares the results to a mobile application via bluetooth. The aim of the competition, open to citizens of the US who are enrolled from Class 5 to 8, is to identify a solution to an everyday problem that directly impacts either the contestant or the global population. The winner of the competition is awarded $25,000 along with the title of 'America's Top Young Scientist 2017'.
