Trance Dance

Following the Kecak dance they hold a Trance Dance. They come out a light a large pile of coconut husks, allowing the husks to burn to coals. Then a man comes out on a hobby-horse made out of palm leaves and he tramples through the red hot coals, scattering them, snorting and neighing and not seeming to notice these hot coals he’s scattering about (the audience was also quick to scatter as we realized the coals were coming in our direction.)
I found a clip on YouTube that is of the Trance Dance…if you’re interested, click on the words "Trance Dance" in the title.
You’ll even get to hear some of the chanting, though the synchronized movements of the men isn’t included (they only chant during this dance).
