An 11-year-old girl from New York has earned money towards her college education thanks to her creativity. Google’s 2014 Doodle 4 Google contest challenged children in grades K-12 to draw an invention that would make the world a better place. Contest winner, Audrey Zhang created a device that tackles one of the world’s biggest issues, the need for clean drinking water.

“To make the world a better place, I invented a transformative water purifier,” Zhang told Google. ” It takes in dirty and polluted water from rivers, lakes, and even oceans, then massively transforms the water into clean, safe and sanitary water, when humans and animals drink this water, they will live a healthier life.”
