Yes, David - do you remember the match head inside the blue cone not lighting at all! Really good example of the poor heat conductivity of a gas. Also a match across the blue cone only lights in two places! I must say that I always use the bunsen as an example of how kids MUST experience practical work. I still remember the trill of being in a real lab, having a great teacher and doing the first bunsen burner lesson. May be 46 years ago! But it stuck and the rest is history as they say!
First thing we were shown in Physics was a match inside a Bunsen flame not burning - does depend on which bit of flame.
