How does it work?

A candle burns wax vapor into carbon dioxide and water. When you blow out a candle there is still some wax vapor in the air, which you can heat to relight the candle.

When the wick is lit, the flame vaporizes the candle wax and turns it into heat and light.

However, as soon as it is blown out, the trail of smoke that forms from the wick still contains wax that hasn’t yet burned.

Holding a flammable source close to the wisps can actually reignite downwards and light the wick once more.
