Magical Realist:
I can't see anything else moving on the counter besides the cake cover.
There's some kind of paper thing on the corner of the counter that flaps around a bit.
So, here's what I'm wondering: I'm wondering about sources of wind in the store.
Interestingly, in the video, we can see an air conditioner and a window right next to the counter that the cake top was on. There's also that white box thing on the floor. There's a door next to the counter on the other side. In general, there are quite a few potential sources of breezes nearby.
You realize the cover would have to be lifted up to come off the cake pedestal?
Here's what most glass cake covers look like:
There's no guarantee that
this cake base looks like that. You can't tell from the video.
Some cake pedestals have less of a curve at the edges. Some just have a glass groove that the cake top is supposed to slot into.
So, here's a theory for you: There was some wind or air movement in the room (perhaps from the air conditioner next to the counter) that blew the paper on the side of the counter and also blew on the cake top. If the cake top had been replaced haphazardly, it might not have been resting on the glass base correctly, but rather it could have been precariously balanced. In that case, the wind might have been enough to
just dislodge it enough to move the side off it off the edge of the base. Once that happened, the whole thing could roll over, gaining momentum in the fall off the base and then continuing to move across the counter until it fell off onto the floor.
If the wind didn't do it, then the vibrations from the nearby air conditioner might have done the trick.
What is really needed is a detailed examination of the scene, the particular cake top and base, the environment when the air conditioner was on, more information on conditions on the day it happened (e.g. was it hot and was the air conditioner on?), questioning of the staff to find out how regularly the cake top was not put on the base correctly, and so on.
Of course, you have none of this information, and you aren't interested in hearing about it.
No doubt you will try to dismiss my theory with empty claims that this or that simply isn't possible, but your basis for your conclusion will be assumption piled on assumption, with no new information, as usual. Nothing I say will change your mind that this was the work of a ghost, because you're too emotionally invested in the woo to care if it wasn't.
No..a clear glass or plastic cup is not going to have rubber on the bottom. I've never seen that and neither have you.
Bzzt! Wrong. I have seen that. It's not unusual for pencil holding cups to have rubber bases.
Again, I'm sure you have no way of disproving my hypothesis, and I'm equally sure you have no interest in investigating further.
If there were vibrations enough to scoot a large glass tip jar off, that would also be enough scoot a lighter pencil cup off too.
Not necessarily. The positioning of the items could easily make the vibrations more significant in some places than others, quite apart from any other factors in play.
The best way to sort this out, of course, would be to conduct a few controlled experiments on location. But I'm sure nobody has done that, and you have no interest in what any such experiment might show.
Nothing except the woo is plausible to you. We knew that from the start.
