My thanks to Julia and others who sent me this video link on using a pencil as an emergency light source. Actually, I seem to think I've seen this video or something like it before, but its good to see again.

Aw, Dave, I was hoping you would perform your own experiment and report back to us! Just kidding, as I am definitely giving this one a pass myself. I don't like to play with fire -- I once lived in an apartment for three years and never used the stovetop burners or the oven because it was a gas model and you had to light the pilot light every time.
