Testing if Sharks Can Smell a Drop of Blood

Scientific proof Pixar sits on a throne of lies. Thanks to Bose for their support and for the dopest headphones I've ever worn: https://bose.life/markrober
Also, thanks to Discovery for putting my life in danger.

More info that was promised-
What is likely happening is that the sharks can smell the blood but it's just not in a quantity that is interesting to them especially since they don't love human blood that much (btw, I spoke with a marine biologist and mammal blood is all the same from a chemical marker stand point so cow blood is a suitable substitute for human blood). If I did the experiment again, I would want to test human blood vs. fish blood.
This is the most definitive study done to date in a control lab environment on what is least and most interesting to them: The Biology of Sharks and Rays Peter A. Klimley and Steven Oerding; ISBN-13: 9780226442495. Particularly pages 134-140. Figure 6.7; Table 6.2

Summary: I've always wanted to test if sharks can really smell a single drop of blood in the water from 1 mile away. So I went to the Bahamas in shark infested waters and set up an experiment to get to the bottom of things.

Summary: I collected data at the carnival for a full day. Then I used that information to figure out which games are the biggest scams using science to analyze them and show you how to beat them. I also figured out how much the carnival actually pays for the prizes so even if you win, you lose. And then I visited the carnival with my professional baseball playing buddy to dominate all the games. It worked well.

Summary: Since I was a little kid I always wondered what it would be like to swim in a pool of Jello. Turns out it is really difficult. We heated up the Gelatin in 55 gallon drums and then used gravity to put that jello into the pool.

Why Megalodon (Definitely) Went Extinct
For more than 10 million years, Megalodon was at the top of its game as the oceans’ apex predator...until 2.6 million years ago, when it went extinct. So, what happened to the largest shark in history?

Package Thief vs. Glitter Bomb Trap
This might be my Magnum Opus. Please see my comments below with regards to reports the video was partially faked. Go to https://NordVPN.com/MarkRober and use code MARKROBER to get 75% off a 3 year plan and an extra month for free.
My buddy Sean posted a video with more details of the build: https://youtu.be/IpMxOmUcfOI
Note about 2 missing the reactions in the video (I posted this on all my social channels immediately after it happened)- I was presented with information that caused me to doubt the veracity of 2 of the 5 reactions in the video. These were reactions that were captured during a two week period while the device was at house 2 hours away from where I live. I put a feeler out for people willing to put a package on their porch and this person (who is a friend of a friend) volunteered to help. To compensate them for their time and willingness to risk putting a package on their porch I offered financial compensation for any successful recoveries of the package. It appears (and I've since confirmed) in these two cases, the “thieves" were actually acquaintances of the person helping me. From the footage I received from the phones which intentionally only record at specific times, this wasn’t clear to me. I have since removed those reactions from the original video (originally 6:26-7:59). I’m really sorry about this. Ultimately, I am responsible for the content that goes on my channel and I should have done more here. I can vouch for that the reactions were genuine when the package was taken from my house. Having said that, I know my credibility is damaged but I encourage you to look at the types of videos I’ve been making for the past 7 years. This is my first ever video with some kind of “prank" and like I mentioned in the video, it’s pretty removed from my comfort zone and I should have done more. I’m especially gutted because so much thought, time, money and effort went into building the device and I hope this doesn’t just taint the entire effort as “fake". It genuinely works (like all the other things I’ve built on my channel) and we’ve made all the code and build info public. Again, I’m sorry for putting something up on my channel that was misleading. That is totally on me and I will take all necessary steps to make sure it won’t happen again.
