Did you know your body is made up of 60% water? Your body uses that water in all of your cells, organs, and tissues. That is why you, and every human being, needs water to survive! But what if you weren't sure if your water was safe to drink? That is what happened in Flint, Michigan, where their water was polluted by lead. When people drank the tap water in their own homes, they would get sick. 11-year-old Gitanjali Rao found out about this problem, and decided to create a device that would help the people of Flint!
Gitanjali often watched her parents testing the water in her home, but the devices they used were always slow and sometimes didn't work. She noticed these issues, and decided to design a cheap and portable device that could find lead in water. The device comes with a cartridge that you dip it in a glass of water, which sends a signal to an app on your phone. The app then displays if the water is, or is not, safe to drink! Scientists were so impressed by the invention that last year, Gitanjali was named "America's Top Young Scientist". She was also given money to attend college and to fund her device so people will be able to buy it in stores!
