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:
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.

They are soft-

    Could it have been that the sharks adapted after the first part of the experiment? They realised the scent of blood and noticed the boards and didn't bother going close as they knew it wasn't a real living creature?

    Sharks are pretty smart. they knew the first time that if they conveniently fooled the humans that they don't get attracted to blood. SO that next time humans bleeding in water won't care much.

    The shark can smell cow's blood because it smells more than human but they can't smell human blood that good because they don't smell as bad as the cow's
