Description
PROOF: When I wear a mask on a cold morning, my glasses fog up.
On a cold morning, I can also see the fog from my breath escaping all around the mask.
LESSON: The mask isn't stopping anything, only re-directing it.
That 'fog' is what scientists call "Droplets", which is what they say transfers between people and spreads the virus.
The ONLY way a mask could really work, is if it stopped ALL fog / droplets from escaping.. a simple cloth mask, or even N95 doesn't do that.
