fuel girls

A friend of mine on the burlesque circuit spotted this fantastic hot lady / science mashup: setting pretty girls on fire! No trickery here - the Fuel Girls (NSFW) are a troupe of pyro-minxes who perform a "kick-ass, ultra sexy, fire breathing rock and roll, dance and stunt show". They were filmed as part of Discovery's Time Warp TV show. My friend wants to know what this magical harmless fire gel is, and where she can get some! Any suggestions?
