We just got a wand..

They're really fun to play with and if you have a poi background and can stall really well, they're pretty easy to control.
They attach to one hand, but the trick is to move two hands around to make it look like it attached to both, then people wonder how it can go around your body etc.
Ours have cotton thread.
No, the video only had one string, you can tell by the fact he always leads with right hand, and can go over his head, but btb, he has to unspin.

Great toy, I only got introduced to it this month.
Our is not fire, it's from the flowtoys shop i think, for UV shows... Silver and shiny with a black invisible thread.
Just playing with it at uni made people stop and stare.
Here, Prisna
It really is the use of the other hand that mades the difference.
