Thanks for the testimony and your direct experience, this "solves" the topic.
I would instead use the word "usefuliness" of such clip which is near to zeros (or even, less, because of wrong conclusions).
Indeed. Usefulness is very low. I haven't double-checked the location where they filmed, and only haversted some a couple times in Costa Rica (pacific coast, near Dominical, where there are black beaches famous to the locals) but I had first heard of harvesting magnetite by using magnets on the beach either on some crystal or orgonite forum. Hence, nothing new on that front, I'm sure you can look up harvesting magnetite from beaches and find plenty of 15+ year old references to the process.
For context and scale of my experience, I went twice on day trips to the beach specifically to harvest some, gathering about two gallon jugs of dark material each time. There was a great amount of regular sand pollutants, because I was harvesting it from the surf and the wet material gathers a lot of sand; after purifying it (twice, iirc) I ended up with about a kilo, maybe a half-liter of strongly magnetic pure black material. It looks exactly like what she's picking up; I infer that since she's just hovering the magnet right above dry sand, only the hematite gets picked up, so she gets this fine black crystally sand right away.
I briefly looked at black sand beaches
(
Black sand - Wikipedia.),
apparently there are two kinds, either of hematite/magnetite, or from basalt. The basalt ones wouldn't be magnetic, I suspect. Still there are black beaches listed across the world, and as for america, there seems to be some on both coasts as well, and I'm sure you can gather it near and far too, the beach probably doesn't need to be pure black, I'm sure most of you have noticed once in a while those slighty darker, tarnished-looking big spots on an otherwise pale beach, or otherwise seeing noticing bits and spots of dark sand that stands out on the background. Bring a magnet to the beach next time you go, you can try (and maybe harvest some nice crystals, too!)
Ok, and final note, I watched the video again to make sure I wasn't judging too harshly. They mention that they see the dark sand in many places around australia. There weren't any black beaches listed on wiki for Australia, but quite a few for New Zealand. Though these might more likely be basalt-type. Either way, they mention (paraphrasing), "I'm sure you've noticed black sand before on the beaches, it's everywhere around australia, but now.." so they move on into the fear response, they do not have the presence of mind to consider that it has been there for a long time and that it might be anything
but spike proteins. Their conclusion is foregone.
Nothwithstanding that spikes are nanoscale, it's not like they would form these crystalline macro-spikes (macro as in, visible unmagnified). But, as I mentionned before, it's exactly the type of structure you'll have seen around a magnet if you ever dropped one on a shop floor.
That, I know because my father had big garage magnets used to pick up heavy metal chunks, and he'd always (fairly kindly) grumble at me whenever I laid them on the floor close to the lathe or the drill press. Cleaning metallic 'sand' off a magnet is a real hassle, and as you try to pinch it off it keeps slipping back to the magnet and takes the exact field line shape that they believe are spike proteins.
Anyways. Enough time spent on this video, I dare suggest. Thanks for bringing it up either way!
Let's try and keep the discussion here (including hypotheses) rational and evidence-based.
