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.”

Running for seven years, Doodle 4 Google is an annual contest that issues a college scholarship and grant to its winner and their school. This year, top honors went to Zhang and her water purification concept, which scored the 11-year-old do-gooder a $30,000 college scholarship and a $50,000 Google for Education technology grant on her school.

In addition to gifting cash for higher learning, Mountain View donated $20,000 to charity:water toward providing clean water to schools in Bangladesh. Here’s a look at some of this year’s participants.
