Not all heroes wear capes, some just wear lab coats.

FLINT, Mich— Fifteen-year-old scientist Gitanjali Rao was named Time magazine’s first-ever “Kid of the Year” for her three inventions that are helping make the world a better place.

One of those inventions is the Tethys, which she created after becoming aware of the Flint water crisis five years ago.

Tethys is a small portable device that measures the resistance of lead chloride molecules in lead-contaminated water.

Once the resistance is measured and lead is detected, the device sends the data to a smartphone through bluetooth.

“I hope for my device to be used in every household and school so that everyone has access to clean drinking water,” said Gitanjali in a 2018 video posted by Google on Twitter.

Gitanjali also created two artificial intelligence-based inventions that help tackle opioid addiction and cyberbullying.

Gitanjali is now looking to dive deeper into water issues. She hopes to devise another scientific invention that detects parasitic compounds found in water.
