Gitanjali Rao won first place in the Discovery Education 3M Young Scientist Challenge.
An 11-year-old wants to change the way we test for lead in water.
Gitanjali Rao created a disposable cartridge to detect how electrons move in water. When lead is present, electrons will flow uncharacteristically.
The results are then sent to a user's phone through a Bluetooth attachment connected to a processor. Users view the results on an app. The entire process is faster than other testing options.
The processor runs on a battery that allows the device to be used for up to two years. The mobile app is free, but the other parts cost about $20.
Gitanjali's idea scored her first place in the Discovery Education 3M Young Scientist Challenge. The win came with a $25,000 prize, which Gitanjali said she hopes to use to improve and sell her product — and save some for her college fund.
