Students at Imhotep Charter School developed and manufactured 3-D printed water filters as part of their STEM studies.
A group of the teens then actually hand-delivered the devices to Jackson, Mississippi, where they were used to test contaminated water.
Recent flooding overwhelmed Jackson's already fragile water infrastructure, leaving thousands without access to clean water.
The Imhotep volunteers also taught fellow students at Ambition Prep Academy in Jackson how to operate a 3-D printer.
They also donated one of their printers for Ambition Prep to continue their own project.
