When I was in college, we had a strange little device for generating
smoke in a very small toy of a tunnel.  It had a very small suction pump
with a hose and piece of pipe just big enough around to stick a big fat
cheap cigar in.  You lit up the cigar, stuck it in the pipe, and fired
up the pump.  I seem to remember the cigar lasting for quite a while. 
Sorry I don't have more details.
