Thank you in advance for your time. I found a neat project to do with
my 14 year old son, but would like to know the science behind it so it
will be educational.

Here is the video link.

It is a fire cracker experiment, and I know he will love it, but I am
clueless as to how this makes my car run.

In your car a mixture of gas and air is ignited to push a cylinder.

I don't believe that a say this ... are you sure you want to encourage
your son to 'experiment' with firecrackers?
You might find something harmless, but equally entertaining on this
site: http://www.sciencetoymaker.org/
The water rockets are worth a look.

Experimenting with firecrackers should be interesting and exciting for a
lot of young teenagers. Under expert adult supervision, I would see
nothing wrong with it either. You don't want the makers of the movie
clip to be the supervisors though. You just *don't* light the fuse of a
firecracker with a lighter or anything else with a flame. Much too
unpredictable. You would use a "slow match" fuse or even a
cigarette/cigar for that.

I'm doubtin' she'd want her 14yo experimenting with the later examples
of the slow match either. Maybe those things that come with fireworks,
"punks" I believe they're called would be better.

If they are called "punks" than that's probably what I meant. Sorry,
English is not my first language.

A safer example at that age than a ciggie.

From the fireworks point of view a cigarette is quite safe. But I can see
what you mean.
