    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...

    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?

    <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.

    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.

    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.

    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.

    I'm all for social distancing, but if you're going to talk about science, you have to provide all the details. Specifically concerning your light. Link to which light, the wavelength of UV (is it UV-C?), etc. Really, I just want a handheld for our department and wanna know which light you have 🤣.

    Here’s the problem MIT professor on USA Today did a study of sneezes and they travel 27 feet so if you think social distancing is just 6ft think again. Wear a mask or scarf or stay inside because 27ft is a long way. April 1,2020 just google it.

    Scientists should develop a compound that covers the virus itself such that it does not connect itself to any receptor overall the compound also does not affect the Human cell...The compound should be injected to everyone so that any incoming virus can be stoped for doing so, also when the virus will be covered it would not be able to get into a human cell to reproduce and eventually end up dying ( Corona virus ) Edit : If I have done any mistake then be sure to tell me why cause I always like to learn more 😅😅😃😃 BTW I am Jay Dhabhi...😅😅
