Understanding Water Safety and Innovation

The video highlights the global issue of water contamination and introduces Gitanjali Rao, a young innovator who developed a device to detect lead in water using nanotube-based sensors. Inspired by the Flint water crisis, Gitanjali aims to make a difference through science and encourages girls to pursue STEM fields. She is working with Denver Water to refine her device and hopes to make it widely available soon.
