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://whipr.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.

Hi Mark, I just suscribed. How do I receive my free KiwiCo it please? I went to their site but it doesn't speak of the 1st month free. Help. TKS!


I'm here when this is #1 on trending

Just wanted to say that have a good rest of your day

Interesting little snipit of covid here if anyone else caught that... you don't just get it and then it miraculously disappears. What this shows is that testing for it is inconclusive, unreliable, and the numbers you're constantly slammed with about some huge pandemic is not even remotely accurate. Doesn't mean you shouldn't take precautions, but it does mean you should take what the media would tell you with a grain of salt.

Audrey Li

this actually ended up #1 on trending. i love it how you put so much effort into your videos

Hannah Dion

He always plays the exact same music in the background

Kai C

you had rona

Trevor Bigelow

what if blood tured the frogs gay


Anyone else was horrified when they heard that he got 5 GALLONS of HUMAN BLOOD?

Then when I realised it was cow I was like oh lol

No.Filter Sarah

What people don't understand is that as fun as this looks. This is millions of dollara and proper research and science. The money that went into this...is...well huge. wow

Evan Suddreth

Who else paused the video to see what it would say with the thing at the bottom text

Reace games Up

Sharks: around the world
Shark week opening
Also sharks: naruto swims and sees. Jaws
New sharks: kill mode, activate


I'm pretty sure that fish slurry was not only blood so this experiment is bust.

#1 on trending????????????????
Congrats Mark

Kellen Reese

it was not a good idea to watch this while eating

badar sweatyboy

15:23 idk if its me or not cuz it looked like hes in vr and look at luke suit it looks like space


FYI jaws is not a realistic movie. The creator knows this and is disgusted by the amount of people that kill sharks because of the myth that they’re blood thirsty monsters


I thought he died lol

Paris is a moveable Feast


Guy in the cage: PANIC

Guy with the camera: All Buddy Buddy with the sharks

How much trees do you have to plant to compensate for a trip to the moon?

Ray ruiz

And this is another reason why I don't like swimming in the ocean

Lewis Wells

It wasn't really just fish blood, it was fat and flesh too albeit blended. Maybe you'll have to fly back Mark for a redo :).

Conner Emery

I can’t wait to watch this on shark week!

Lesh Vishwasrao

HOW DO SHARKS " smell" under water? or is that just a way to simplify what's actually happening?

Bryce Corson

He was in the Bahamas and he was trying to talk with Oprah witch means one thing. He was going to Epstein’s island

Piotr Borowski

Why both "Rona" tests (positive and negative) were made on the same day?

Julia Red

I saw this in konosuba


Where'd you get the human blood?

Jason Karl

Oh hey and here's an idea How about don't put a man in the water full scuba gear minus the fins. Kind of hard to propel that weight without them

Justin Villegas

Poor sharks ????

aren finelt

I remember this episode last year


shows blood and says corona virus in a video
youtube: so you have chosen death.

Jaxxon Brown

How did he get human blood????

Jeffrey Stoesser

Sounded an awful lot like a little girl when in the cage....

Jimmy Orozco

As a vegan this brakes my heart


but the camera guy was never guarded....

Dawood Nadeem

No one:
Mark: gets covid and then proceeds to surround himself with sharks


Look at those teeth at 13:18
