Shark Attack Test- Human Blood vs. Fish Blood

  • تم نشره في 2020/08/ 9
  • I personally got in the water and tested if Sharks had a preference of human blood vs. fish blood. Get your first month of KiwiCo for FREE!!!
    Point of clarification: A few people have pointed out the dates on the negative and positive Covid tests are the same. You'll also notice my doctor was Bob Newby from Stranger Things. Turns out there is a lot of personal info on a Covid result test and the part that says negative and positive wasn't easily readable so I photoshopped up something that solved both of those issues and didn't bother changing the date. No conspiracy here. I promise I actually got Covid and would have much preferred to actually filmed on the original schedule and not had to deal with it even with the private jet silver lining.
    Also, thanks to Discovery for putting my life in danger. #SharkWeek begins August 9th.

    Here is a link to that tiny exercise machine I was using the the jet. Luke (my shark expert buddy) invented it and it's really clever. He's launching a Kickstarter really soon-

    Sorry this took awhile. I've got 8 absolute banger videos I'm currently working on through April 2021 but it turns out the Rona slows things down a bit. They will be worth the wait! For updates, follow me on social stuff @MarkRober.

    This experiment is FLAWED!!! They said that sharks are more attracted to fish blood. This was not proved in this experiment because they used pure blood from a cow and for the fish they blended the fish meat/flesh along with their blood. No different that putting a slab of fish on a hook only better because it is concentrated into a smoothie. So they proved that sharks are more attracted to fish (not blood) than cow blood which I could have concluded without going through all the experimentation.

    IF you test positive for the virus you should get retested in another three days and then three later. Virus testing is substantially inaccurate, the blood test truly shows if the virus is in your system. Specially due to the fact that you were asymptomatic.

    Hi Mark Rober, I was wondering if you could answer this question in your next video: If hot air rises, then is hot air less dense then cold air and if so, will you be lighter standing in it than cold air?
