Burning oil -[ HMM ]-

The soldering iron again; no solder was used this time around to generate smoke.

 

I originally worked on a different idea using matches and some rancid olive oil from a long-neglected bottle, but I couldn't get a long-lasting smoke trail, much less one I could get to respond to the fume exhaust over my workbench. Out of frustration, I decided to use the iron, using the oil for smoke generation.

 

Yes, I replaced the tip after the photoshoot. I'm not convinced olive oil, whether fresh or eight years past its best-by date, is an acceptable soldering flux.
