I have seen a video where some type of cord/wire was used to burn a line, the material burned almost instantly...does anyone have any idea what kind of product this may be? 
Those little sample squares of plastic laminate you find at big box stores work pretty well. You can sharpen the edge with sand paper and get a fine line or use the whole thickness for a bold line.
AThe set I have has small wooden balls one on each end(leave that along guys) that the wire is run through the balls.
