Never trust a single person engaged with ANYTHING to do with "Covid" or "Masks" or "Tests and swabs". They are ALL in the HOAX business. It is NOT in the best interest of any human to use any of it. If one is so afraid of their own shadow that they cannot stand up for themselves , cannot handle people approaching you for not wearing a mask, then wear a cotton one you make and wash the crap every time you take it off. This video, I'll bet, is their clever way of building a REASON for the creepy moving things in masks all around the world. They know people everywhere are buying microscopes etc to study their masks... and they might lose their sheep. Besides, all these synthetics and "nano particles" are Exactly what should Never be near the passageway to the lungs of a human or animal.
