How a slinky falls in slow motion

    This is not just true of slinkies - if you release a steel rod from the top, the top really starts falling before the bottom. If you hit a tennis ball with a racket, a wave has to travel from the strings to your hand before you feel it - and the ball is well on its way to the net by this time. If you hit a golf ball, the ball is well on its way to the hole before you can feel it. Rigid bodies aren't truly rigid and understanding this is essential to understanding the way the world works

mmm I think the bottom part stayas there because it'w waiting for the top part to reach therminal velocity. I think if you drop from an helium balloon (use a rope to keep the balloon in place) and then drop the top part, the bottom part will drop once it reaches terminal velocity (as I said).

"which means there is a torsion wave traveling faster than the compression wave"... Actually the collapse isn't a "compression wave" in the same sense as a sound wave. It's just the bunching up of the falling slinky. If it's not clear, the slinky is falling much slower than the speed of sound, the reason the bottom appears to hover is because gravity is still balanced out by spring tension until the spring becomes unstretched at that section of the spring.

I think it's going up cuz spring physics but it technically cant because it's falling It's almost just like how our eyes can fixate/focus looking at an object even when you move your head There's like that counter movement that makes it look like it's not moving There are dancers that use that concept to do the robot head dance or performers that hold things as if it's floating but in reality they practiced the counter movement to make it look like its floating/in the same space.

More than gravitational pull, the upper portion of slinky is pulling the below part, apparently that's why it won't fall untill the stretch is lost.

As I noticed; There's an info. called "Gravity", that affects the whole system behavior, influencing it to start shrinking from one side toward the other side, rather than shrinking equally from the both sides toward the center !! The same info. is not existing in free space, so the system behaves there in un-biased way!

The Slinky works by pull force . As the slinky is pulled by gravity, and the slinky be pulled by stretch, the slinky stays as long as these forces are equal. Making slink no go

What if a staright thread or rope is dropped? Will it follow similar characteristics? Every section of the rope is supported by a section above it. When you release the top of the rope, the tension is released and this information will propagate at a finite speed down the rope. So, will the dangling rope follow the same characteristic as the slinky? Or will it be different? Is it because of the flexibility that release of tension takes more time in a slinky to progress down. How this phenomenon can be represented mathematically, that can be applied to all falling body, i.e if body is rigid, the information of release is bound to propagate very fast (almost instantly) and if body is flexible, it will take some time. Can you share mathematically, what's happening and how to predict how a dangling body will fall, to understand better what's happening.

The twisting motion is because the speed of sound measures the speed of force transfer inside the object. Since solids have a high speed of sound, the rotational force is transferred almost instantly. But since tension isn’t relieved until the accelerating mass catches up, it stays floating.

The top part applies a force= -kx on the bottom which cancels the effect of gravity for the bottom part if you consider only bottom part as a system... If you consider whole slinky as a system then it's centre of mass is always in a free fall and it's towards the falling part where there is mass accumulation over the small space, so bottom has to stay intact in order to conserve the instantaneous position of the system's centre of mass.

My question is that tension on the spring is F=-kx. With time x decreases but the opposing force, gravity is constant. Therefore sides of the equation are not equal and it shall start to move just as it was released. Perhaps slower but still it should be in motion. Which part am I missing?

Curious you are looking for a wave to explain the twisting, when it is the lack of compression which causes that twisting. It occurs as soon as the top is released, because the distance the wire travels between the same spot on two coils becomes shorter, until they touch. This forces the wire to push down its length, following the rigid form of its substance. This creates a rotational force that is related to the rigidity of the substance of the coil. This is why the plastic slinky is more unstable, as it allows the coils to expand out and deform more that its metal counterparts. Oscillation is always awesome, no matter how many fancy words we use for it though :)
