This demonstration on combustion reactions was performed during one of my science classes. This is how I did it:
1. Safety attire first: goggles, apron, long sleeves rolled back, and students with long hair had to tie it back.
2. Rubber tubing was attached to a gas jet at the lab table.
3. Methane gas was allowed to bubble through a solution of soap detergent, water, and a little glycerin contained in a beaker.
4. The bubbles of methane rose up out of the beaker (methane is lighter than air) and were scooped by hand.
5. A burning splint was used to ignite the bubbles.
I was unable to do much staging of this (other than making sure the periodic table was in the background) because I was more concerned with safety issues. The only lighting I had was the fluorescent lights in the room and the flash on my camera.
Post-processing in PS: adjustments in curves, saturation and contrast, crop, save for web, sharpen.

ACTION!
this must be nice to do
rather nasty reflection (flash?) on the periodic table in BG and flame a bit overexposed. but I quess, this is hard to get a good exposure of because of large dynamic range.
best of luck
Tough to argue that THIS meets the challenge :) ... This is pretty crazy and looks like a genuine scene from the classroom. This guy seems strangely calm!!! The only thing i might mess with is the white balance since there's a tint of yellow green in the background.
