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

You should also go subscribe to the CrunchLabs YouTube channel cause we’ve got some bangers in the pipeline- youtube.com/crunchlabs

    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 turns out it's really hard to find 5 gallons of human blood legally" Mate, your Google search history must be a treat 🙂
  • imagine being a fish and you're watching your body in the afterlife and you just see two guys BLENDING your soulless body

    This guy actually takes 6 minutes to get to the plot but still makes it entertaining every second of the video
  • “It’s really hard to get 5 gallons of human blood legally.” Can confirm.

    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.”
