    I guess your mother never taught you to cover your mouth when you cough.and sneeze. Amazing that we all lived this long. Too bad it doesn't filter out fear and lies :). Have another beer, boy :)

    Uncle Rob, this is a fantastic video, for "medical mask" examples. Would you consider doing a video using the popular cloth masks/face coverings? Bandanas, homemade, the type of neck gaiters that you wear like a tube, etc.? It would be much appreciated by those that wear them, or those that have been issued them by their employers as standard wear..... Thank you.

    Hello Rob, please make another video using makeshift cloth masks that most people are wearing, rather than surgical masks which are in short supply. My concern is by making a video about surgical masks and using it to represent all masks, you may be misleading your audience into a false sense of security when wearing an ordinary non-surgical mask, potentially causing them to disregard distancing guidelines. Thanks!

    Should have tried it with cloth masks that the public are suppose to wear. It’s good to know that medical grade masks do what they are suppose to do.

    the major flaw in this is simple. Every single time I have seen someone at Walmart sneeze or cough they take their mask off. Nobody wants a snot filled mask. The other part where this is flawed is that spray isn't a microbe. That mask is not protecting yu from microbes.

    What you have proved is covering your mouth prevents a sneeze/cough travelling in front, the same experiment can be conducted with sneezing/coughing into a handkerchief so you haven’t really proved anything though?

    this does not portray what actually happens when we sneeze or cough. Minute particles do make it through the mask. But the theory is that the mask will slow down those minute particles so they don't make it the 6 feet that social distancing requires.

    There is either a very right time for a mask or they are not going to help. ...It's about the _HANDS_ ALWAYS... If you touch a mask with 'dirty' hands, one has defeated the purpose of the mask because of "wicking" and has brought virus right to the doorstep of its favorite first home, the nose and mouth.

    Not sure how one can claim to be 'definitive' about the efficacy of a paper mask in preventing microscoping droplets without some kind of microsope. Still, if you want to go with a YT entertainer for 'definitive' 'facts' then be my guest.

    Uncle Bob! Gentlemen! Turn yourselves on ASAP to MMS! Both of you do a Chlorine Dioxide purge, protocol 1000, not higher. Decalcifies and oxygenates, vivifies and helps regenerate, stay on top of the game, not played in it. My challenge to you is this. To AT LEAST research what MMS, discovered by Jim Humble, is all about. I'm doing it (a second time) too. Amazing amazing AND COVID-DESTROYING too. huh! Better than Hydroxychloroquine by a long shot. No possible eye-damage with Chlorine Dioxide. a.k.a. MMS. Don't fk w/ diss! Read through, search any hot ailment/malaise/sickness/disease, read some testimonies of lives (not stats!) You know there's a difference in this "information (manipulation) age". I'll be back. You be forward.

    Nice, but Sneezing/coughing/breathing does not work as a concentrated spray it works more as vapor, thats why its way easier to get contaminated in close spaces as the virus assimilates with the air as it travels through water vapor than on open places with or without a mask. Basically they work to stop it in the front direction, like stopping it with your sleeve or a folded piece of cloth, but it will still contaminate the air around you.

    While this is a great example of how masks work, it’s mostly for the people that already wear masks. The people who are anti mask that bother to watch this will just double down on their own falsehoods. You can’t argue with stupid.

      Nobody is anti-mask. Some people are pro-choice, though. It should be your choice to stay home and your choice to wear a mask.

      @idontevenknow Also, why don't we have a legitimate scientific study at least mimicking the breathing in and out of both sides and the accumulation of the aerosols. This is a cool trick, but nothing more than that. Nobody ever said they wouldn't block large droplets, it's how much of a role do aerosols play in the transmission and how effective are masks at blocking them. I can't remember the last time I was in a public area and someone coughed/sneezed within 6ft of me right at my face.

      What happens when the mask becomes over saturated and covered in dust? Then everything your walking by gets caught in the moist area of the mask... masks are for sterile environments

    This test is flawed from the outset, first of all people cough/sneeze with varying degrees of force. Also those cans are under a certain amount of pressure, some more and some less and so, depending on how much it started with and how much has been dispensed it would affect the constant velocity.
