Well thats got me thinking.I didnt even know about "Vortex generators".
A Vortex Generator is usually a very small strip of metal designed to start the airflow spiraling around (like a miniature tornado) to give the airflow along certain parts of the wing a more energetic air flow, which in turn does things like making a control surface more effective or lower the stall speed of a wing. The 737 has several small ones on it's wing:

If you look in the picture above (one of the cleanest 737 wings I've ever seen
), the VG
's are plainly visible just behind the black line that is painted behind the slats on the wing's leading edge...they just look like little metal strips arranged in a tidy row.
A smoke generator, if placed ahead of one of these, would allow someone to see the vortex that these vortex generators create
