Aerosol and Droplet propogation - VIDEOS of Human breathing cough sneeze

[Joel McMinn]

Videos link is bolded below.  Suggest copy/paste this when forwarding to others, for readability, and under YOUR signature your audience may be more likely to take a moment to digest this.

google visual test of air velocity at mouth and nose - nice list of results.  Relevant hits apply to EXIT (exhale, sneeze, cough).  Need to search further for INHALE.

This 2013 article  and author's published 2011 article had useful data and analysis, even more useful videos during schlieren and shadowgraph imaging.  The 26 references at end of 2013 deserve a looksee

• A fully opened multi-ply kleenex seems best for reducing the reach of a cough or sneeze.  Better than N95 mask.
• Normal breathing - down velocity from your nose seems better than exhaling from mouth.

You should access the articles and videos for yourself. However for ez viewing, I downloaded the 2011 videos to google album Nose and Mouth Exit Airflow videos

Credits to these peer-reviewed articles are in the INFO line of each video, and following:
