Start watching at like 1:19 and see the kids don't have their own staff. Then at around 1:24 they do.

I think you're seeing a magic trick that's been around forever: https://www.youtube.com/watch?v=o-KDuOvMAfQ&t=80s

Ahhh! When he said staffs I assumed he meant people, not staves! Yeah, that's 100% CG. Here [1] you can see where the kids take a stance where it was to be edited in, and if you pause at the exact moment - it looks pretty bad, with something like a lightsaber just popping in the kid's hand.

Hmmm. Not sure what to make of this. I wish it was possible to see the raw unedited footage. It makes me question everything else.

If you watch at 0.25 speed, you can see the staff is actually a magician's cane. It's a coiled up bit of plastic that springs open when you release the ends. You can see similar tricks on YouTube, like https://www.youtube.com/watch?v=d-j6G4sPwWU

That's true, and the wobbliness of the cane is indeed characteristic of this device.

That definitely does seem viable. I suppose never say 100%...

That's fair, I think the fact that at 1:16 when they land on the floor one hand remains coiled as if holding something in it makes that a likely possibility. Guess I wasn't expecting a magic trick!
