      @mikael englund a freeze dryer freezes the product and lowers the pressure, and is designed to do that, im talking about freezing with nothing but vacuum, and/or separately putting a chamber that is already in a vacuum state into a freezer with the product inside insulated from the surface of the chamber, not really the same method a freeze dryer

    The condesation is becausw of hot air from ur mouth and water that are already in the air atmosphere.. when u take a cold bottle from fridge it sweats.. but yeah wear masks adults.. for some reason kids dont need to wear them..

    what about the they spray that comes out around your cheeks and sides of your nose under your eyes where none of the masks seal properly, doesnt matter if your wearing a mask, some of the spray will still get out, just on a different trajectory, though most of it should be stopped

    The condensation on the mirror is from the moisture in the cooler air meets the warm air from lungs,that's how fog is created, talk on the mirror in a hot room and see how much condensation collects on the mirror.

  • SimplyEmily94

    This is the worst video I've seen from you yet, not only because it's biased BS, but because there's nothing scientific or useful about this. It's literally just you saying, "look, masks work," even though they don't actually do much to prevent the spread of viruses, even according to the CDC and WHO. I'm disappointed.

    • Metal Puppet
      Metal Puppet

      There are multiple studies showing that they do in fact work. They are not stopping the spread single handedly. However that is not the point. They are proven to reduce the spread by over 40%. We wont completely get rid of Covid. But we have to lower the numbers so hospital cases go down. And masks have been proven to help doing that

    To truly protect yourself from the virus, you need to quarantine for the rest of your life.

    • Metal Puppet
      Metal Puppet

      @Mung Bean prove it then! You cant can you? Situations like the one in Italy were and are VERY real. Every health care worker will confirm that because its the truth. Those people are working under inhuman circumstances and you are not just not giving a f about that but you are also putting your loved ones in danger. I'm purposely not talking about yourself. If you dont care about getting it then that is fine with me but you KNOW that there is scientific proof that you can pass it on even if you're asymptomatic. You do not know you have it and you're still highly contagious. Thats how situations like in Italy came together.

    • Mung Bean
      Mung Bean

      @Metal Puppet people like you are easily told what to think. They will tell you what propoganda to believe and you will obey. This hoax is easily disproven, but you can't see.

    • Metal Puppet
      Metal Puppet

      @Mung Bean this is far from a hoax. Its not about stopping it. Yes that is impossible. But thats not the point of masks. The point of masks is to SLOW DOWN the spread so health care systems can catch a break. The pressure this thing puts on all our health care systems is insane and nowhere near compareable with the flu

    The problem isn't whether masks work or not anymore, the problem is how selfish others can be and taking that extra time to put on a mask, or wash their hands.

    • LestatTVPickle

      @The Happy Oyster that's the problem, "I" it needs to be, if WE all wear masks WE'LL be fine, until then, this will be a years issue not year.

  • Nberente5

    Maybe take a carbon dioxide reading inside the mask also. Not to mention, being a prescription eye glass wearer, the “air” typically exits the top of the mask so showing it there instead of the front would be a more apt measurement. Just my .02 but you probably won’t read this or will disregard it, in an attempt to keep the facade rolling. So maybe I’ll keep the change. 😬

  • nursefuzzywuzzy
    nursefuzzywuzzy

    Masks work when people wear them correctly, but I see so many people with their nose out or the mask not sealed around their face, or they pull the mask down to sniff something or read something if they are wearing glasses. It's an ineffective mode of protection.

    • Metal Puppet

    Just put a pair of glasses on. You’ll see the water droplets and see how they are deflected from an outward trajectory to a trajectory along the surface of your face along the masks edge. Air, and thus water droplets, will always escape the mask but the distance and amount of water will be greatly affected.

    Everyone that wears glasses knows your breath goes up and out not through. While there could be a little benefit at times because a lot condenses on your glasses. but most will still go up and into the air. Plus you cannot see and likely to walk into something.

    The poor explanation of condensation, and improper use of term "droplets" makes the information almost null...would expect more from someone about to get a degree in meteorology. No mention of absolute, relative or specific humidity. No mention of water vapor being a gaseous state of water. No mention of particle size vs. filtering capability. No mention of how your lungs exchange water vapor into the exhaled air. Just people screwing around with spray bottles. Kind of like forcing a square peg in a round hole.
