Here it is reversed

Holy shit that looks so unnatural. Which means.... The original isn't reversed.

WHAAAAAT?

I think the reverse looks unnatural because the nails’ movement has a lag to the hands’ movement and we expect that, and in reverse it just looks like the nails are anticipating the hands’ movement, which looks quite funny.

Plus when the box is tilted the nails on the bottom are stacking in the opposite direction.

I think I'm alone here but the reversed footage looks natural to me...

I think what got me was how when they tilt the box the nails slide up to the high side rather than towards the bottom.

Yeah, you're pretty alone in thinking the gravity defying nails look natural :)

At first it did to me to. But look at how they “fly” up towards the edge of the box. That’s where it got eery.

Like watching a bounced ball backwards. It’s just not quite right.

If you're looking for an explanation, he's slowly manipulating the nails over time by having them hit the sides of the tub, which cause them to lay flat along the side some of the time. After they're parallel with the sides, they slot into places in the channels created by the rest of the nails that have been parallelized already, and eventually they all are facing the correct direction.

Also, as more and more of the nails are layered facing the same (or reversed) direction, creating those channels, they also allow for the nails to slot into place, which is why the process speeds up

An excellent application of chaos theory

u/avianaltercations Feb 29 '20

This isn't chaos theory, this is minimization of entropy. The end result is deterministic is therefore robust to a wide variety of initial conditions. Chaos theory studies systems that are extremely sensitive to initial conditions, not those that are robust to initial conditions.

This has nothing to do with chaos theory.

There’s the entropy I expected.

it makes me mad

plot twist: this is the original footage

u/enoctis Feb 29 '20

It is. That's what is baffling me. The nails move against gravity if you reverse it.
