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

This is an excerpt from a video I made 10 years ago - seemed like the perfect thing to show in vertical format. I was unaware Action Labs had recently made a video about the same thing. A regular video should be out Friday/Saturday this week.

Action Labs video was trash and full of unscientific such as “the bottom of the slinky doesn’t know that it has been dropped yet”. Good job Veritasium!

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).

The way I like to think of it is it takes time for the information that you have let go of the top ring to reach the bottom one. The information travels in the form of waves through the slinky

Someone taking shots at Action Labs low key stating that they did something first 10 years before while the action labs guy takes all the credit. Without actually realizing this was still old knowledge 10 years ago shown in tv shows, documentaries and books everywhere but no one credits the first guy that did this or studied this, everyone just steals and profit.

This is actually how everything works. It's just that most things are dense enough that the top of the object accelerates the bottom quick enough we don't notice.

The bottom part is being pulled upwards while the top part is the one that's both falling and pulling towards the center. It's not really that kind of amazing. Unless, there's some use for this. Do the same thing, but on a nice smooth floor. You'll see both ends converge towards the center or towards the side that was set off last.

Weird thought but That would be the same if a lot of people were holding each other on a ledge, and the first person let go. Then the last person wouldn't fall at the same time, that person would still be "floating" until the person above starts to fall Right?

"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.
