    Good video. One question for you, Do you know what is the MAX distance from which one can relight the candle?

    Basically what happens is, the smoke is uncombusted carbon oder semi-combusted carbon (CO), because the wax is mostly carbon and it vaporizes faster than it can burn in the air. So when you light the white smoke, which is very finely divided Carbon in air, it combusts and turns to carbon dioxide, which is colorless (which is why the smoke seems to disappear). The flame itself is just gas being ionized from the heat of the carbon-oxide reaction, but the smoke burns so quickly back down to the candle, that the air around doesn't get heated enough to be ionized, which is why you don't see a flame jumping down from the match to the candle, but just the candle flame reigniting.
    Interesting sidefact for cars: If you see a car accellerating and a black cloud is coming from the exhaust, it means that the engine doesn't get enough air to properly burn the fuel. It's often a sign for the engine either being too cold or badly adjusted (which can happen during a non-professional tuning)

    If you use the old fashioned candles they used to sell in the local shop in the uk you can get a 1meter smoke stream and light it from that high! ive done it :D

    with no wind you can do it like 8 inches above it. I've done it and i couldn't believe it

    Question: If you have two candles next to eachother, and wind blowing the smoke onto the other candle, if you do this halfway will it light both candles?

    Oh by the way once the smoke and flame connect there is a flame front that travels down the smoke. typically a blue flame since there is so much oxygen available.

    Smoke is flammable. smoke is unburned and heated particles of the material that was burning. look flammability of smoke.

    actually what happens is, smoke contains a high amount of carbon, coal also contains a high amount of carbon. remember when you put out coal fires that the coals are still hot, the smoke does that too, therefore igniting the wick.

    I hve a theory theremis still heat there when you blow it out and you add a little more heat and burn of the rest ofnthe smoke which allows oxygen to feed the fire

    my guess the wic is already at a combustible temp and when u blow it out the smoke grab the heat from the match and helps jump the temp back up but wat do I know I diddnt go to college

    watched the vid now saw u guys explain it NOPE I wasn't close

    Hey mates, If you haven't done this do it, it creates a pretty big explosion and i would love to see the chemical reaction in slow motion, you put car engine oil into a plastic bottle (like what coke uses) and then add pool chlorine to it and run! this creates a fireball what looks awesome and would love to see it in slow motion
    thx for your time and love your videos

    If you did it in dim light, you actually can see the small fire particle trace down the smoke curve. Anyone in Calculus? This is an example of a particle moving along a curve, although the curve is made by mother nature and is random

    The reason it's relighting is the gas is being heated back into a plasma.

    why is it that when you need to put a fire out you put water on it but then to get something to set on fire quickly you put water on it then add fire? i dont think it makes sense

    • Shawn Dubay
      Shawn Dubay 3 years ago

      Smoke is flammable. It is unburned and heated particles of what was burning. They put out the flame but the wick is still hot and produces smoke. The flame relights the smoke or "unburned particles and candle re ignition happens.

    easy. The gas from the burning match travels down to the very hot tip of the candle and it simply lights up

    It's cause the visible part is made of particulates (very small bits of unburdened fuel) and when you light these particulates they catch fire but you can't really see it as the particulates are so small and they burn so fast, and they then burn back down to the candle in a similar way to the powder you used in your fire breathing video.
