Scientific proof Pixar sits on a throne of lies.

Also, thanks to Discovery for putting my life in danger.

Connor was the beast feeding the sharks underwater. He has some amazing footage for licensing and his own YouTube channel.

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

Thanks to these folks for providing some of the music in the video:

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.

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.
