      Please share this with anyone who doubts the science behind social distancing. The road ahead will be a bit bumpy, but we totally got this fellow Earthlings :)

        @4:30 Sorry to be a stickler, but most viruses are RNA viruses. I loved the video... And I loved your video filmed here in Western Australia with the boys from How rediculous. I live in Perth, too bad you didnt have a meet up event... I love your channel. It consumes many hours of my free time...

      2. Ana Alfonso

        Very interesting.

        Mark Rober my family goes on 30 minute walks and we go to our friends houses, ring the doorbell with our elbow, then run back to the sidewalk and have a conversation like that.

        I have just reviewed the Italian subtitles and they are fine. If it's up to you @MarkRober please make them public

      I'm here from April 4th to say... It's hard to unite people when behind a faceless enemy. We are to busy trying to find someone to blame and be the one who's "right" in a no win scenario, that we hit the curved harder then any other country.

    19. jenn lemmelin

      FALSE INFO! Viruses are not living germs.

      1. fillie is real

        @jenn lemmelin That is partly true, virus are not alive by DEFINITION. That's because they need another organism to live. When we say that a virus lives in a surface, we mean that if someone touches the virus, it's still able to infect him

      2. jenn lemmelin

        @fillie is real viruses are not alive

      Remember when you said “when the next pandemic comes” in the drinking nasty swamp water video?

    21. Glitchiono

      Yeah , the bridge of your nose and your cheeks don’t count ( I think? )

      why does this have 6,846 dislikes?



    29. Beiya Tang

      the poor fourth kid that thought he would get a handshake: "am i a joke to you"

    30. Carrolyn Arcos

      I enjoyed this video, but I think it's important to point out that it's not that people think it's okay to go to work sick, but that people need the money and there's not enough paid sick leave for them to do so. People will go to work if they're sick now because they're worried that they'll get sicker later and need that time. We should give more sick time to employees, and create a work culture where it's okay to not work if you're sick.

      Mark: <a href="#" class="seekto" data-time="145">2:25</a> Me:Chop off your arm,no arm no hands. No hands no sick

    33. Aaron Wayne

      Very, very good experiment. It should be played by the CDC and on the news.

    34. Warren G Cosgrove

      hi mark. first of all thank you for this it will proboly be boring for the rest of my class when i share this to my teacher but not for me also in your next video please shout out to me at warren g cosgrove. thanks!

    35. RainbowRose 769

      You say that we should be more careful when we are sick with the flu, but what about school? Upperclass kids need to be at school otherwise you will end up being way behind. So school literally force kids to come to school sick. What do you suggest?

    36. Michael Wright

      love the AOL t shirt he's wearing. SAVAGE!

    37. The idiot

      <a href="#" class="seekto" data-time="315">5:15</a> The way he didn't pull up his sleeves bother me

    38. The legendary Sword

      Ur at my school

    39. Damon Cox

      First time viewer......WELL DONE MY FRIEND....Spot on,VERY ACCURATE AND INFORMATIVE....I found this to help me explain to someone else how easily viruses spread,THIS IS BY FAR THE MOST ACCURATE REPRESENTATION OF VIRAL SPREAD AND WAYS TO TRULY AVOID SPREADING TO ONE'S SELF OR OTHERS

      1. Damon Cox

        @mixio hili What difference does that make concerning the spreading of ANY DISEASE........NO disease has independent locomotion,they ALL rely on transmission from host to host BY THAT HOST'S PHYSICAL ACTIONS. THAT WAS THE WHOLE POINT OF THE VIDEO.........TRANSMISSION

      2. mixio hili

        The corona virus has no DNA. It's not "alive" like a bacteria. It does, however, have RNA. A virus can only have one or the other.

    40. james gilbert

      More great propaganda. Yeah!

      1. fillie is real

        How do you think this is propaganda??

      2. mixio hili

        Someone farted in the middle of my zoom class😂😂😂😂

    42. Shelly B

      Thank u Mark - awesome stuff! Is there a way u could compare wearing gloves to using hand sanitizer? (Cashiers/baggers). Also wearing a mask? I know u cant put this powder in ur mouth but maybe another idea to show results?

    43. Stupidbro

      <a href="#" class="seekto" data-time="377">6:17</a> Ooh! That reminds me! Someone should do a variation to see how much/little better fist bumps are than handshakes.

    44. Sean Ehle

      Any Invader Zim fans getting some nice giggles of nostalgia, here?

    45. Him

    48. Julia Sowden

      This is the best video I have seen so far explaining this. Thanks!

    49. puffystrike

      Chinese media says its the Americans who spread the virus to China in the first place

    50. Enriching Exchanges

      You are incredible. Seeing is believing, and there is no better demonstration of the critical importance of self-defense mechanism like social distancing and washing hands, which are entirely within one's power. Bravo! This is the definition of service.

    64. Kailee Craig

      Great video! It would be nice to give shout outs to all the janitorial staff who have been going out every day to keep surfaces and equipment clean every day, especially with how this video ties back to the importance of surface cleanliness. There are a lot of them out there still working every day working and they haven't gotten a lot of recognition they deserve.
