I can’t help but think of the Coal Mine exhibit at the Museum of Science and Industry in Chicago. They’ve been repeating the same demonstration of one of those safety lamps since at least the 1950’s.

That’s a flame, not an explosion.

As if the heated relations out on our streets weren’t already strained enough.

Dampers wanted.
I remember doing this at school.
You can put a piece of mesh on top of a Bunsen burner, then light the gas as it comes through the mesh. The you can lift the mesh up, and the flame will stay above the mesh, with a gap underneath. (You can only lift it so far before the gas flow becomes unstable and you run the risk of fireballs).
