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

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 prizewinning solution: a small, finshaped device that increases fresh airflow in airplanes and redirects pathogenladen air out of circulation.
