It sounds crazy, but Mark Rober decided to do some experiment and test if sharks can smell a blood in the ocean water of the Bahamas.
Yes, it sounds interesting, but it is also very dangerous. He was interested how long the sharks needed to smell blood before they attacked?
They put sea water, fish oil, urine and cow’s blood. The results are really interesting.
But after this, they go further and try the human blood. These results will surprise you a lot, you don’t expect this.
