Face Shield Visualization Simulation (VIDEO) Florida Atlantic University This video is under embargo. Please login to access this video. Caption To demonstrate the performance of the face shield, researchers used a horizontal laser sheet in addition to a vertical laser sheet revealing how the droplets cross the horizontal plane. Not only did the researchers observe forward spread of the droplets, they found that droplets also spread in the reverse direction.
