Checking exhaust system for leaks

You haven't seen the "Red Neck" home made smoke machine?? I think it was here on FABO somewhere (video clip). You get a 2 liter soda bottle poke a hole in the cap large enough to fit a cigarette. You poke another hole in the bottom of the bottle to fit an air hose hand held blow gun then light a cigarette , stick it in the cap (with the burning end inside the bottle) then blow air (slowly into the bottom hole). The air will burn the cigarette down causing smoke to come out the end of the cap (where the cig filter sticks out). Then you just duck tape it to your tail pipe and have someone look for the smoke coming from a leak while you blow smoke into the tail pipe!!
