I don't get it. All I see in the video is condensate from the sudden cooling of air above the pans of liquid nitrogen being blown by the force of the person's breath. Of course that's stopped by a mask, because the air will leak out the sides instead.Cortopassi wrote: ↑Sun Jul 12, 2020 10:55 amI found this one a bit more satisfying.vnatale wrote: ↑Sun Jul 12, 2020 12:42 am Bill Nye Is Here to Demonstrate That Face Masks Get the Job Done

I do agree that masks will help prevent droplets from a cough or sneeze getting on someone else in close proximity, which would certainly transmit the virus. But that's it. I doubt they accomplish anything at a distance, or outdoors where the droplets disperse quickly, or to protect you if someone does cough or sneeze on you. They may even make it worse since you'll transmit the virus very effectively to yourself from the outside of the mask when you take it off, because you're not trained how to do it and likely use the same mask repeatedly.
