Step-son has some chemistry homework as they have been investigating chemical compositions. His homework is to put together a project demonstrating chemical compositions, their reactions and if possible subsequent uses.

When he mentioned this to me the first thing that came to mind was a good old match head powered cannon with potassium nitrate and sugar fuse, however this got me thinking. If I were to help him with the project and then we build such a canon to demonstrate the chemical reaction so he could film it to use in his power point presentation, can this land us in hot water?

Are we best off just doing the base reactions and then having him explain how these reactions could be used i.e. in a canon etc.

I guess the men in blue are probably already on their way with flashing lights ?

Trying to remember to when I dealt with fireworks - I believe it is OK for anyone to produce small quantities (not sure of the definition of 'small' here either, I suspect a few grams) of compositions for their own personal experimentation, but once that composition is contained in something, i.e. a firework or in this case a cannon, it becomes something that could cause you problems.

Depends on whether you have a spare slot for it. (kidding)

I'd steer clear personally, it's not worth the risk.

I'll just show him the videos on YouTube then and let him devise his own conclusions. Cheers everyone

:lol:

Stop trying to make education fun, he's not supposed to actually enjoy it.

Yes, or rather, I used to up until 6 months ago. Family still does.

Nope thats not me, terrible shame. He is happy just describing other people's experiments on YouTube however some practical science would have been fun
