    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.

    Im not tryna disprove you but I think that the sharks also liked the meat that was blended with the fish blood. The human blood was only blood so they didnt want to eat it. They actually wanted to eat the blended meat so a lot more went there. Obviously you cant blend up human meat like that😅😅 but next time try to only use fish blood.
