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!
