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.
