Someone finally did a "smoke test" on a mask, to see how well it stopped particles....

Fauci and the other fraudsters ordered y'all to wear masks, eh?  "To stop the spread of the chinese virus", eh?   Hmmm....

Ya know, that just might work!  I mean, Fauci et al are "experts," so they should know all about that stuff, right?

And I guess if you're one of those alien beings who inhales but doesn't exhale, it might work.
