How a slinky falls in slow motion #shorts



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

  1. 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.

  2. Leaving a comment on every short i stumble upon in order to verify the law of miracles, such that atleast one comment will gain a lots and lots of likes and replies

  3. DEREK! Man, I hope you see this. I'm fascinated to know what happens if the opposite is done. Take a spring that has spaces in the helix at equilibrium. Stand it on a surface so that it compresses under its own weight force. Now make the surface disappear. Does the top stay stationary until equilibrium is again reached?
