That will probably wear off - she is sussing it out - how can it move on it's own?! Or maybe she is putting a marker at the top so she can count how many rotations she's done lol. Our syrian had a running battle with a flying saucer at first - to achieve getting to the top and keeping it still without sliding back down again. I have a video of it! He achieved it eventually - near the end of the video - and then stopped bothering to try. He was also trying to see if he could use it as a ramp to get over the side of the playpen I think.
You can see him working it out and I swear he did a victory lap at the end after achieving it - then looked up at the playpen - realised he couldn't get over the side and gave up!
