Google rewards 11-year-old Doodle winner with $30,000 scholarship

An 11-year-old girl from New York now has money to help fund her college education thanks to her award-winning Google Doodle.

For its 2014 Doodle 4 Google contest, Google challenged school kids in grades K-12 to doodle an invention that would make the world a better place. In her doodle, 11-year-old Audrey Zhang illustrated a device that imagines one solution to the problem of finding clean drinking water.

"To make the world a better place, I invented a transformative water purifier," Zhang said. "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."

Now in its seventh year, the annual Doodle 4 Google contest awards the winner a college scholarship and school grant, so it's a lucrative honor both for the young doodler and the doodler's school. Google gave Zhang a $30,000 college scholarship and bestowed a $50,000 Google for Education technology grant on her current school. The search giant's arm also donated $20,000 in Zhang's name to charity:water to assist its efforts in providing clean water to schools in Bangladesh.

This year's competition was tough. Among more than 100,000 submissions, 250 state finalists, 50 state winners, and 5 national age group winners, Zhang emerged victorious. The folks at Google even invited her to work with artists to animate her drawing and bring life to the water purifying device. The version seen on Google's home page today reveals the mechanical water purifier with gears and wings as it slurps in the water from a lake while the animals of the forest look on in wonder.

Last year, Google bestowed the top Doodle 4 Google award to 12th grader Sabrina Brady for her depiction of her father's return home after having served in Iraq.
