11-year-old wins $25,000 science prize

Rao claims her own lead detector is pretty much faster than other lead detectors out there.

Rao's invention was inspired by the water crisis in Flint, Michigan, where cost-cutting measures led to contaminated drinking water by lead and other toxins.

The fair won her a $25,000 prizewhich Rao already has made plans on how to use it: "I plan to use most of it in developing my device further so that it can be commercially available soon," she told CNN.
