Smoke is caused by inefficient burning of carbon based materials. Those big diesel trucks that launch huge clouds of smoke out of their tail pipes? That’s unburned fuel. So, when the candle is blown out the wick/candle is still burning but inefficiently and creates lots of smoke. Holding a flame to the trail of smoke causes the unburned carbon in the smoke to ignite and trails all the way back to the wick which then fully ignites and starts burning efficiently again. I wonder if you could hold a flame to those big plumes of smoke coming out of a suped up diesel truck…
It’s really fun to use the slow mo camera on iPhones with this trick.. you can literally watch the flame travel through the smoke

Ah, witchcraft I see.
But this is a chemical reaction…
