  • You know it's been popular, Rod.

  • What's that?

  • Are slinky drop video.

  • That is popular, isn't it?

  • Yeah.

  • You want to do another think you drop.

  • That's not a slinky.

  • This is a slinky.

  • That is a That is an excellent slinking.

  • We should drop that one.

  • We want to see whether a long slinky and where 50 made us up here.

  • Whether long slinky works the same as a short slinky Because some people on YouTube don't really believe that it's gonna work the same where they want to see it.

  • We're about to find out.

  • All right?

  • I'll go filming from the grass and you drop this.

  • Thank you.

  • Okay.

  • Here you go.

  • Ron.

  • You say?

  • Yeah, that was a good drink.

  • You get it?

  • I don't know.

  • I think so.

  • We gotta check the cameras.

  • Well, I think it tended to tumble on us.

  • It got got right down to the bottom.

  • And I think it's going too fast and tumbling.

  • I think you'd better.

  • We better do that one again.

  • We're going to do it again.

  • Yeah.

  • All right.

  • Thank you.

  • I'm not a problem.

  • I saw that.

  • That still tumbles when it gets to the end cleared to May that you wouldn't want to be sitting on the end of this under an aeroplane.

  • No, now, much better to actually have a parachute.

  • Exactly.

  • What do you think about the explanations that have been going around on the Web?

  • People talking about the center of Mass is falling with the acceleration due to gravity 9.8 meters per second squared.

  • Is that true?

  • Yes, it is.

  • And then the bottom end.

  • People are saying it's actually shooting up to meet the middle.

  • Is that happening or what do you think I want?

  • The rest from its staying abreast say they need that explanation.

  • It almost makes the most sense just to consider in our frame of reference.

  • Nothing has changed at the bottom until the top of this slinky compresses.

  • So why not just take gravity out of the equation altogether on?

  • Let's see what happens to our hearts a little slinky.

  • All right, let's have a look at that sky.

  • This was prepared by Rod earlier when I hit the right hand in the spring, the left hand and doesn't move until the compression wife travels down the length of the spring and changes attention of that end.

  • Yeah, so it's about the same thing is the Slinky, but obviously there's no gravitational force involved.

  • Correct.

  • Cool.

  • All right, well, thanks so much.

  • We have learned a lot about Slink, ese.

You know it's been popular, Rod.
