The effect is somewhat delayed...see the video for a better understanding. The video Doesn't show the long flame-shot very well. It's also much louder and more spectacular in real life.
Look at this crazy photo... this is what 30fps of HD video can do.
Step 1: Gather Your Materials
1) A standard household match. Do not use strike-anywhere matches (unless you like "unauthorized pyrotechnic events'')
2) Tiny drill bit. A 1/16 will work best, but I couldn't find mine...so I used some unknown micro bit.
3) 1 single red pop-gun cap.
4) Something to remove the powder from the cap with. Like a pin, toothpick, or an X-acto.
Step 2: Prepare for the Drilling
Step 3: Drilling by Hand
Don't use powertools here, or you could hurt yourself. I once drill a 1/16 hole ALL THE WAY THROUGH MY FREAKIN THUMB when doing this with a Dremel.
Step 4: Empty Your Caps
One you get some unexploded powder from the cap, go to step 5!
Step 5: FILL THE MATCH!
Now draw a frowning face on it, and watch the video on the first page.
