NPR featured a video (3 m 29 s) on making as safe-as-possible-do-it-yourself COVID-19 masks.

Masks have two benefits: keeping in the respiratory droplets we all eject while talking, etc., and to a lesser extent protecting yourself from droplets from others.

The film is based on advice from researcher who have been studying the effectiveness of mask materials.
