This 6 ½ minute video by a 17 year old shows how his invention can change the world, protect us from pandemics spread by air passengers, and save billions of dollars.

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.
