Are you trying to make something where a fan will pull the smoke for you?

I assume he was using an 80mm computer fan, they vary greatly in airflow, a good site to get one from would be newegg.com, although I'm sure a CompUSA or whatever you have down there would have one aswell. They run on 12V DC, so get a 12V DC power supply, build a chamber, get the fan in there the right way, and it will draw hits for you. Dunno why you'd want it, but that's how it could be done.
