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- https://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 https://crunchlabs.com

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

Mark Rober Former NASA and Apple engineer. Current YouTuber and friend of science. Answers to some common questions: 1) I studied Mechanical Engineering in School. I did my undergrad at BYU and Masters at USC. 2) I worked for NASA JPL for 9 years, 7 of which were working on the Curiosity Rover (I made a video about it you should def totes watch cause it's probably my favorite of all my videos). Then I created Digital Dudz (made some videos about this too) and eventually sold it after 2 years. Then I worked for Apple in their Special Projects Group doing Product Design as a Mechanical Engineer for 5 years. As of 2019, I just make my monthly YouTube videos. 3) Link to free and therefore substandard build plans for my custom workbench can be found below. 4) I make a monthly toy we build together on a video, that gets delivered to your house that teaches you to think like an engineer.
