That's strange...I would have thought that JP-8 would still create smoke. Having been an aircraft refueler, I know that JP-8 is essentially just a more refined version of diesel (of sorts). I could see something like AvGas not producing any smoke, since that's essentially a more refined version of kerosene, but JP-8 would still smoke if it burned. Maybe shooting it into the exhaust system doesn't provide enough heat to actually burn the JP-8 or something, since it's actually possible to put out a match with JP-8 without igniting the fuel.
(Mind you, I'm not suggesting to anyone to attempt this, since it's only done as a demonstration under controlled conditions and with proper safety measures in place)
