Interesting, only problem I see with it is the virus is supposedly 10000 times smaller than a grain of salt, not sure how big the ether particles are but I’d bet they’re a lot bigger than the virus.

Great - now figure out how to test blowing aerosols through the mask and maybe your test will mean something. As it is, it's useless because most people believe the mask will protect them from inhaling the virus, which it won't. It may stop droplets, however aerosols pass through most masks unimpeded. And as everyone should know, you can't see covid 19 without an electron microscope, it's that small, and therefor, easily carried in an aerosol. Nice try. Now do some actual science please.

Ok now do a cloth mask test and I'll believe you because everyone already knew medical grade surgical masks work. Such a stupid test that wasted everyone's time, unless the original intention was to deceive?

Has this proven that masks help when it comes to breathing? No argument that masks help defend from sneezes or coughs, but not sure it proves masks help prevent close-up spread.

So an aerosol can mimics a true cough or sneeze? A virus particle is not visible to the naked eye. At least the MID.

The virus is carried by aerosoles. Within them, they can survive and stay in in the air and survive for quite a long time. When the aerosol dries out, the virus dies.

It's a nice illustration of something, but it doesn't apply to masks preventing the spread of a virus, it's Ridiculous!!! If a mask would really help prevent transmission of e.g. COVID-19 or any other virus, etc., then China and other nations in Asia would have no virus cases whatsoever as they've been always wearing masks to wherever they go for decades.

Haha.. yeah.. if you feel there's a problem with people sneezing straight in your face as soon as you walk outside the door with their mouth full of fluid.. the mask might actually have a very temporary effect haha.. During all other circumstances though.. ie 99,9999999999% of the time.. the mask will only destroy your health with constant lower oxygen levels and bacteria inhaling.

"On a broader scale the scientists have not reached consensus whether COVID-19 should be called airborne or whether it is transmittable only from droplets. Airborne or not, when the water component of droplets dries up in the air, the remaining bits of floating virus are called “droplet nuclei,” which are lighter and able to travel long distances." https://www.genano.com/infobase/how-easily-does-covid-19-spread-through-the-air Basically his test proves that although the droplets don't go too far through the mask in sufficient quantities to light the fire, they do escape the mask and have the potential to be breathed in by the next person wearing a mask or not, when they come in contact with that air. Have you walked behind someone that was smoking before? You can smell their smoke for a considerable distance downwind from them. Of course this test isn't entirely scientific anyway since water droplets and ether droplets aren't the same. I read about another test where they used light to show that some masks actually reduce the size of the droplets so more of them escape through the masks.

Doing a test on masks outside proves nothing as in open air the virus disperses rapidly. Test should have been done in an enclosed space with little ventilation to prove how the mask really works. Before anyone calls me a "mask hater" no, I'm not. I wear a mask every time I go into a shop but no need to wear one when walking down the street.

People think this experiment is brilliant but I think it has some big flaws. Spewing water out of your mouth several feet isn't the same as a cough. I think that most people agree that covering your mouth when you cough is appropriate, we've known that for years. Maybe a huge uncovered sneeze is closer to his example, but then again, most people cover their sneezes. Also, people aren't walking around coughing everywhere with the force of a massive sneeze. His experiment would need to show how regular breathing works but I doubt it would be that dramatic. We also aren't accounting for people resuing masks over and over throughout the day when they get shoved in pockets and car cupholders and are likely filled with accumulated bacteria that they put on their face over and over again and end up breathing in all that accumulated bacteria and who knows what else.

"Good trouble" time. Seriously, I was exposed to MUCH WORSE stuff in school (books w/ the N word OH NO!) and, well, one teacher showed us a "clinical video" about sex as an act. None of these saves lives like this dude and his beer.

Uncle Rob, please do a video for differences in mask types. People are arguing only the n95 will protect. Which isn’t true. All masks will, not just the n95 as you tested.

I love it! What about showing the distance when wind blows? Also, that was with a force like coughing or sneezing, so what about just breathing when walking and breathing with running? Also be nice to see smokers in no wind and in wind , meaning how far exhaling travels, just a thought to show what our breathing can do to others
