Imagine you want to capture a balloon popping, mid burst. Use an acoustic sensor to activate the shutter, and play with the delay until you get the precise timing.
I never thought about using the firing channel to release the shutter, I guess this would be the most accurate way to get the precise timing after the burst.
It would be interesting to capture an "average" burst, by using the channel firing method, setting the delay in small increments. You could compile a slow motion video, and if you control the explosions to make them as similair as possible, I think it would work quite well...
In reality, I stand there, shutter button half-pressed, waiting for the right moment I can capture three frames per second, so I'll take three in succession to increase the chance of catching the burst.

I've been thinking of doing that in the future, especially for wheels.
What composition were those red stars?

I would like to do the same again with a shorter exposure to show the tail better, and wash out the red less. In real life, they're a very deep red, and leave a big bushy trail of sparks.
The stars are the Strontium Nitrate/Titanium from AFN iv. I finaly got them working nicely. They really are amazing to watch - my favourite effect star so far.

I know its off topic, but could you possibly post the formula for those stars (perhaps in a more approprate thread?) ?

If you have a sparkler you can write your name in the air with the sparkler then at the last moment use a hand held flash and fire it at the subject to freeze them in the picture frame. To practise (and save sparklers) you could use a torch to write your name then flash the subject with a hand held flashgun.
Best to use a tripod and a cable release or else you will add unwanted movement to long exposures. If you dont have a cable release then set up the camera on a tripod or wall and open the shutter holding a black bit of card in front of the lens. Remove the card at the vital moment and return it when the effect has been captured. I hope this helps.
