I'm aware that this simple (n=1) demo isn't how you culture viruses or model spread of SARS-CoV-2.
But colonies of normal bacteria from my mouth/throat show the spread of large respiratory droplets, like the kind we think mostly spread #COVID19, and how a mask can block them!
What does a mask do? Blocks respiratory droplets coming from your mouth and throat.
Two simple demos:
First, I sneezed, sang, talked & coughed toward an agar culture plate with or without a mask. Bacteria colonies show where droplets landed. A mask blocks virtually all of them.
This weekend the @RamsNFL and @Patriots play in the Super Bowl. Here's a great story of @theslater18, former @UCLAFootball player, who exemplifies character and work ethic that he learned from his dad, Jackie Slater, a Hall of Famer with the Rams. https://t.co/eUPYPxarqC
