A typical Bunsen burner has a single cone of flame. The wing tip (fish tail) changes the shape to a wide narrow flame which covers a greater area for the amount of fuel used. This is called spreading the flame.
This modification of the flame shape makes it easier to evenly distribute the heat of the flame to soften the glass without having any hot spots where the glass would be very much softer and less controllable during the bending.

approximately 2000 million years, i might say And by the way ignoramus, this is not any longer "magically" the legs sprouted. It took a jointly as. in basic terms some non secular nuts in US have self assurance in magic. And we are no longer "evolutionists", purely somewhat nicely knowledgeable human beings. Now you pass back on your Bible and study it lower back like a great little boy. It has each little thing you ought to comprehend. Bless the Lord, Amen.

To spread the heat out - if you heat up glass in one spot, it will probably shatter. Spreading the heat out softens it so you can bend it properly.
