The crazy way 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.

      not a "hack" a cheat. its ok to be there. its ok to be niether here nor there. its ok to be anywhere but the inside of the horizontal axis of the slinky when there are perturbations in the gravity of the bottom. its always now.

      @John Jacob Astor here's something else that should be tried, what if both ends of the slinkies were attached to bearings ? Asto unload the twisting moment on the slinky then what would happen when released?

    In the description you wrote; "If you hit a golf ball, the ball is well on its way to the hole before you can feel it." You're making assumptions about my golfing ability.

    Now what if you have a portal gun and a steel rod. You shoot one portal at the ceiling and the other one at the floor beneath it. Now place the rod in between the portals. Will the rod fall down? If yes, what would happen if you weld the top of the rod to the bottom? Will it then fall down? And what would happen to a slinky if attached to itself the same way as the rod?

      Gotta suspend something off the ground but in the event that the roof collapses you want an extra couple of seconds to keep the thing touching the ground? industrial grade slinky.

    Well, that's a wormhole, when you go into the beginning, it collapses but the end doesn't collapse until you get to Well, that's a wormhole, when you go into the beginning, it collapses but the end doesn't collapse until you get to it! 😬

      In zero gravity, what would be the slinky do? Would the slinky retract towards the centre of the slinky??

    Does the top fall faster than gravity alone would cause?

    I'd say it's because of contracting force is adding to the gravitational force, making the center of mass fall faster than normal fall. Because of this, the bottom part remains in position, as it counters the shift of center of mass. Similar to why you can't move forward by shifting the center of mass in space.

    So if I had a heave duty slinky hanging like that, and a person hanging on to the bottom the of the slinky, they would just float there tension was released above?

    Did you notice how that Slinky also look like the vibrations in a magnetic field like the one that wraps around Earth.

    Cool, but I'm not sure your explanation is spot on... I don't think we should to think of it as a each coil falling onto the next one; rather, it's that once a coil no longer has the upward tension force acting on it (meaning that the coils above it are no longer stretched), then the only force left is gravity. Maybe just semantics though...
