Experimental principle:

生活中的科学小实验——隔空点火

After the candle is blown out, a ray of white smoke will be formed in a short time.White smoke is a small particle formed by wax steam when it is cold. Therefore, when the flame is exposed to white smoke, the white smoke (wax steam) is lit. The white smoke is connected to the candle core, and the candle core is lit.
