Okay as good as the twilight lighter trick is, it isn't what is being used in this routine. Jim Pace sells this device, and I reccomend anything made by Pace. The gimmick is called the "Flicker" and can be found here.
Why yes it is, for the Pace gimmick I believe it uses butane, the kikuchi uses possibly a liquid fuel such as lighter fluid. I'd go with the butane because it is easier to control and less of a hazard of lighting your entire hand on fire .
