YouTuber Tests If Sharks Can Actually Smell A Drop Of Blood From A Mile Away
Do sharks really smell a drop of blood from a mile away? To complete the test procedure, the YouTuber Mark Rober put himself in the middle of the ocean, on a boat, surrounded by sharks.
Rober graduated from Brigham Young University with a degree in Mechanical Engineering and worked at NASA for 9 years before moving on to pursue other engineering pursuits.
Mark Rober didn’t just chuck himself in a tank with a docile shark that’s been studied for years, he decided to put himself in the middle of the ocean in the Bahamas where there were sharks galore.
So, Rober placed four surfboards equidistant from the back of the boat in the crystal clear waters of the Bahamas.
Each board hosted two liters of a different liquid, which were pumped into the ocean for an hour, and then count how many sharks went over to check them out.
The bottles contained fish oil, cow’s blood, seawater, and urine.
The surfboards were anchored, and the experiment began. After 20 minutes, there wasn’t a lot of action around the boards, especially at the fish oil, urine, and seawater (control) boards.
“I think it’s safe to qualitatively say that if no sharks came to check out 15 drops of human blood a minute in the middle of shark-infested waters, you’re probably going to be okay with a small scrape,” Rober revealed.
“There certainly won’t be some kind of feeding frenzy with a single drop of blood from all sharks within a mile.”Mark Rober
That should certainly help loads of people relax about going into the ocean with a small scratch because, let’s be honest, we’ve all thought about it at one point or another.
But that’s not to say that sharks aren’t ferocious predators.
That’s what a group of blokes discovered as they were on a fishing trip in America.
In a video taken from the boat, the grey figure can be seen lurking ominously below the water, edging closer and closer.
As the calm among the fishermen rapidly evaporates, the shark then surges above the water and rips the bait from the vessel, Jaws-style.
Credit to the guys, it’s a very excitable losing of their shit, rather than the absolutely petrified losing of shit most of us would concede in such a situation.
