Shark Attack Test- Human Blood vs. Fish Blood

    Sorry this took awhile. I've got 8 absolute banger videos I'm currently working on through April 2021 but it turns out the Rona slows things down a bit. They will be worth the wait! For updates, follow me on social stuff @MarkRober.

    1. You are not using actual human blood. 2. The fish 'blood' contains more than just blood, as you've added fish paste to it. The results from this test are basically invalid.

    Perhaps the fact the the 'fish blood' also had other miscellaneous fish bits in (whereas the mammal blood did not have miscellaneous cow bits in) may have skewed the results? If you had used blended cow (or un-blended fish, blood only), would you have the same result? 🤔

    Covid-19 tests are unreliable and don't actually test for SARS-CoV-2 which has never been shown to be the cause of any illness. That is, the gold standard Koch postulates have never been satisfied. That's why Covid-19 is a *SCAMDEMIC*

    I can't believe some of you. Are y'all really mad about them killing 20 fish... I swear, some of y'all shouldn't be on the internet if your this soft. First of all, science usually requires some for of sacrifice. Thousands of rats have died from covid just to test vaccines. Knowledge is a tradeoff. Also, we as humans consume so many animals that it is hypocritical to say they are wasting the fish. Humans merely poisoning the planet kills more fish a day than this.

    Plz quarantine if you indeed tested positive having no symptoms does not mean false positive, heck on a cruise ship without masks they had 40% of cases without symptoms and 80% on a cruise ships that wore masks without symptoms, if people like you do not take it serious we are doomed.

    Sharks actually just have poor eyesight- like when they bump the cage at the end (they're not actively searching for him, just wherever that fish smell is). They're just like clumsy aquatic wolves lol

    I kinda chuckled at how in his last video he kept reassuring us that no animals were harmed and that he went the extra mile to ensure the squirrels’ safety, and in this video he puts fish in a blender. Idk, I though it was funny.

    He really believes the Earth existed for millions of years??? If you do research, the sun shrinks 5 feet per hour, that’s 43,825 feet per year, and that’s 8 miles per year. Now multiply 8 by only a billion years, that will give you 8 billion miles. So only a billion years ago, the sun would’ve been 8 billion miles closer to earth. The sun is 93 million miles away from earth currently. If the earth was over billion years old, it wouldn’t even exist because the sun would evaporate it instantly because of how big sun was at that time. The earth 100% not older than a billion years, simple math proves it.

    Am I the only one thinking that it is not a pure scientific experiment if Blood smoothie also contains flesh, bones, organs etc. and probably spreading way more "smells"? A true experiment would be blood vs blood, not blood vs smoothie. Nonetheless, cool vid as always
