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.
Quote: 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. |
