The Inertia

Mark Rober, if you hadn’t heard of him, which you’d be forgiven if you hadn’t since YouTubers are a dime a dozen these days, is actually a pretty educated dude who puts some interesting scientific questions to the test. He’s a former NASA engineer and, as he puts it, a “current YouTuber and friend of science.” Well, using a shark cage he designed (thing looks advanced), he tested whether sharks prefer human blood or fish blood. You can probably figure out which they prefer, as he again blew the “sharks as human predators” thing completely out of the water (pun intended). But it makes for interesting viewing, nonetheless.
