Shark Attack Test- Human Blood vs. Fish Blood

I personally got in the water and tested if Sharks had a preference of human blood vs. fish blood.

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.

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- www.kickstarter.com/projects/whipr/whipr

I started a company called CrunchLabs where we build a toy together and then I teach you all the juicy physics for how it works. So if you want to learn to think like an engineer and have really fun time doing it, check out the current promotion where you get 2 FREE boxes at crunchlabs.com

    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.

    If this would have gone wrong: Former nasa scientist dies while trying to prove that sharks don't eat humans
  • “It’s really hard to get 5 gallons of human blood legally.” Can confirm.
  • @user-iq3yh7lg5n
    This guy actually takes 6 minutes to get to the plot but still makes it entertaining every second of the video
  • imagine being a fish and you're watching your body in the afterlife and you just see two guys BLENDING your soulless body
  • Can we appreciate this man kept his channel so family-friendly that he said "heck" while being eaten by sharks

    "It turns out it's really hard to find 5 gallons of human blood legally" Mate, your Google search history must be a treat 🙂

    Loved mark being scared shitless that a nurse shark, one of the friendliest sharks, got its head in the cage

    Mark, August, 2022: “My wife doesn’t know I’m doing this, but I’m totally going to the moon. She thinks I’m just doing a launch video. I just didn’t tell her what was being launched.”

    Luckily, we didn’t see when he blended the humans for blood. That's why his channel is so great
  • @Zacyyyyy
    "Oh crap, that was loud.." these words were the last we heard from mark
  • @ThreeSonsfun
    This was amazing I hope he does somthing like this again
  • Mark: “I’m in the Bahamas with a bucket of blood.” Me: “Mark... not again...”
  • @xaifer2485
    "Something i learned working at NASA" has to be the biggest flex in history
  • @adalynplays5219
    the way I actually jumped when the shark came after him when the lid was open. I was so scared 😭
  • @norbert9451
    Not sure I am fully getting this. There is at least one other diver next to the open cage doing the camera recording, but we should be worried about the guy climbing out of the cage?🤔
  • @Aledharris
    “Everyone was back at a safe distance.” Camera shows them ten meters away.
