A high school senior's garage became ground zero for solving a water crisis her community couldn't afford to fix.
In a Warrenton, Virginia garage an 18-year-old Kettle Run High School student named Mia Heller built a membrane-free water filter the size of a bag of flour, three modules, one litre a pass, and her turbidity sensor logged 95.52% of microplastics pulled out by magnetic oil.
