Mark Rober | Shark Attack Test- Human Blood vs. Fish Blood @MarkRober | Uploaded 4 years ago | Updated 2 hours ago
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- 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
