Raymond Wang is only 17 years old, but he's already helping to build a healthier future. Using fluid dynamics, he created computational simulations of how air moves on airplanes, and what he found is disturbing -- when a person sneezes on a plane, the airflow actually helps to spread pathogens to other passengers. Wang shares an unforgettable animation of how a sneeze travels inside a plane cabin as well as his prize-winning solution: a small, fin-shaped device that increases fresh airflow in airplanes and redirects pathogen-laden air out of circulation.
