okay see the nature of the flame of a Bunsen burner depends on the balance of gas and air. When thers too little air the gas mixture doesnt burn completely and will form a glowing yellow flame. With TOO MUCH AIR, the flame may burn inside the burner tube; that is, it may ''strike back''. Hope I could Help

As boys, we used to get bunsens to strike back by hitting the gas tubing with our fists. The flame then jumped from the chimney to just above the jet, making a peculiar noise, too.
I must say that, as a teacher, the fuel has changed from town gas to natural gas, and perhaps the bunsen design has changed, too, for I haven't seen this happen for at least 20 years.
