Good Feels #10: 12-year-old Girl Invents Fast Lead Detector


In 2014 the source for drinking water in Flint, Michigan was changed and residents were exposed to high levels of lead in their drinking water. A federal state of emergency was declared and residents were instructed to drink bottled water.

Gitanjali Rao heard about these events and invented a lead detecting device at the age of 12. Instead of a several day process to send samples to a lab and get results back, her device detects lead in seconds using carbon molecules.
