My Best of Web submission comes from a paper published from Florida Atlantic University. Researchers set out to visualize the fluid flow paths created by different mask options used to try and reduce the spread of the COVID-19 virus. They investigated the use of face shields as well as masks that used an exhalation valve. Videos were captured showing a model of a person wearing a mask simulating a cough or a sneeze. Particles from this expulsion scatter light from laser sheets, allowing the flow to be visualized. The high contrast of the bright green flow on a black background makes for stunning and relevant images.

    I appreciate you taking the time and energy to put this informative article together.
    I once again find myself personally spending a lot of
    time both reading and posting comments. But so what, it was still worthwhile!
