The narrator, Mark Rober, a popular science YouTuber, designed a specialized human-shaped shark cage and spent a year testing the behavior of sharks in response to human and fish blood. The experiment was conducted in The Bahamas during Shark Week. The results showed that sharks are indeed attracted to the smell of fish blood, but not as much to human blood.
In the second part of the experiment, Mark decided to place himself in the center of a feeding frenzy to observe the sharks' reactions. He was wearing a shark cage and was surrounded by a large number of sharks. The sharks were attracted to the fish blood he released and tried to eat him, but Mark was able to escape safely.
The experiment was a success, and Mark learned a lot about shark behavior. He concluded that sharks are more attracted to fish blood than human blood and that they have been on this planet longer than dinosaurs or trees, giving them ample evolutionary time to develop their instincts.
1. The speaker designed a specialized human-shaped shark cage and found himself in the middle of a shark feeding frenzy.
2. The cage did not prevent sharks from entering.
3. The speaker's curiosity led him to conduct an experiment in The Bahamas one year prior, testing the reaction of sharks to human blood.
4. The experiment involved pumping out 15 drops of human blood per minute for an hour.
5. The results debunked the myth that sharks react violently to the scent of human blood.
6. The speaker then wondered if sharks would react differently to fish blood and decided to test this theory.
7. He returned to The Bahamas as part of Shark Week, this time not alone.
8. The speaker initially tested positive for coronavirus, which led to him missing the planned experiment.
9. He found a loophole to travel to The Bahamas on a private jet.
10. The speaker and his teammate, Luke, created a fish blood smoothie.
11. They conducted an experiment to see if sharks would react to the smell of fish blood.
12. They set up two surfboards in the water, one with fish blood and the other with human blood, and observed how many sharks approached each board.
13. After one hour, they found that the fish blood board had 134 approaches from a shark.
14. The speaker then decided to get into the shark cage filled with fish blood smoothie.
15. He was wearing 10 pounds of steel chainmail for protection and his vest was filled with 20 pounds of lead weights.
16. The sharks reacted aggressively to the bait, and the speaker had to defend himself.
17. The speaker eventually exited the cage safely, and he concluded that sharks have been on this planet longer than dinosaurs or trees, and their instincts are rewarded for smelling fish blood.
