Part 2
If we were to use chain link fence as a stand in for the mask & use a bucket full of bouncy balls as a stand in for the Rona. We will need to run the fence parallel with the ground as a stand in for Negative Pressure breathing. (Gravity is doing the work to simulate us breathing in) What happens when you dump the balls at the fence? Some will bounce completely around the fence and not entering it, some will bounce & enter a different hole & most pass right through. This was a dry experiment & does not include humidity or breath vapor. Lets continue with the next part.
