Also, why did the smoke ignite while the candle without smoke did not?

Here is his explanation: 1) When you are burning a candle, you are essentially vaporizing the liquid wax into a gas that is flammable. This vapor can then be used as fuel for the candle flame. 3) Therefore, as you hold a flame close to the smoke it will light the unused wax vapor that is in the smoke. And another question, why does the candle ignite even faster in the smoke trail? Why does the candle ignite even faster in the "smoke trail"? The trail is actually vaporized or evaporated wax. It thus ignites immediately.

Consequently, why can you relight a candle from the smoke chemistry?

When you blow the candle out, vaporized wax briefly remains in the air. If you apply a heat source quickly enough, you can ignite the wax and use that reaction to relight the wick of the candle. Although it looks like you're lighting the candle with smoke, it's really just the wax vapor that ignites. You can also ask how do you relight a candle without touching it?

Also, what makes a candle relight?

When the flame is blown out, the hot embers from the wick ignite the magnesium powder, producing tiny sparks. This, in turn, ignites the vaporized paraffin hydrocarbons, which relights the wick. Can you relight a candle after blowing it out? As soon as you blow it out, the trail of smoke released by the smoldering wick still contains a bit of wax that hasn't fully burned. When you hold a fire source up to the wisps, they can reignite and cascade back down to relight the candle.
