I just love the uneducated, I love watching them say stupid things, I love watching them make fools of themselves. I love it when they get mad and scream and yell, and wag their finger because they think they know things. Like the people that say mask don’t work because you can smell farts thru them.
It may be hard for them to understand that things can be so small that you can’t see them. Like viruses, bacteria, and molecules, but they are there, and they do have a measurable size. And size does matter.
Masks are used to filter particles out of the air. Each mask has an effective rating for how small a particle that mask can filter. Some masks filter smaller particles than others. When someone farts you can smell the fart because it contains molecules of methane gas. A single molecule of methane gas has a size of about 380 Picometers, which is really small. A single Covid-19 virus has a size of about 20 Nanometers. In order to understand the size difference and put that into perspective, if one Covid-19 virus was the size of a house, then in comparison one molecule of methane would be the size of a golf ball.
So, yes you can smell a fart thru that mask, but it does not mean that Covid-19 can get thru, because in comparison Covid-19 is the size of a house. But hey, you keep believing your fart theory, because you got yourself some edju-ma-cation on Facebook, and you knows it to be true, and I will keep laughing at you.
