Eminem's Love The Way You Lie

I was wondering what the girl is using to hold the fire in her hands in the first 30 sec of the video?

would've been nice to include a link in your request, this way ppl don't have to oogle the stuff you ask about...

hvr I suggest this because it's by far easier than for a production mgr to break his head on how to accomplish it irl

I thought perhaps it was a hidden palm torch initially, until right at the end where the dude in the vid catches fire completely, clearly CGI as above.
