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.

Raymond Wang: How germs travel on planes -- and how we can stop them

How germs travel on planes -- and how we can stop them

Innovative airflow design could reduce airborne pathogen transmission on planes by 55 times, enhancing passenger health.

A simple, overnight-installable device creates personalized breathing zones in planes, drastically improving air quality.

Reducing germ spread on airplanes isn't just about health; it's a cost-effective defense against billion-dollar epidemics.
