Why does a flame make noise when I blow it out?

I found that when I blew out a candle it made a noise... or maybe it was my breath that made the noise, but the noise only happens when the flame goes or is going out. I also find that my stove makes the same noise when I turn it on.

Are flames hollow?

Looking at a lighter flame the other day I wondered whether the inside of the flame was hollow(devoid of flame)? Obviously fuel can only burn with the presence of oxygen this would suggest that just the outside of the flame where it comes in contact with oxygen is actually burning, if so how thick is this 'flame wall'?

Why do flames "lean" towards each other?

I was fiddling around with some candles before a dinner party, and noticed that when the flames are put close to each other they are attracted to each other, and lean in towards each other. Why is this?

Could a bunsen burner work in reverse?

Bunsens are commonplace in the lab, but suppose that one were to be lit in an atmosphere of methane, such as on Titan, with oxygen being fed through the hose. Would the flame look any different? Is it even possible?
