If that had of been nozled it would have been ok and not ploughed into the roof , part of the rockets stability is the thrust of the motor, the only time any of mine have done that is with a really heavy header on but thats my own fault

It had a nozzle . The BP obviously wasn't powerful enough or the nozzle was the wrong size. Made one hell of a noise though. Sounded incredible, not like a usual firework rocket but something HAMAS might launch at Israel or something. Insane

I had a bit of an 'event' with a neighbour recently. This was when I had only just started making BP rockets so it was all trial by error etc. Anyway i made half a dozen or so rockets of varying strength's/compositions to test. I set off 5 of them in a field about 5 minutes walk from my house and all CATO'd or didnt have enough lift to take off. No problems though as I was in a field with no houses within 500 metres. However I forgot to fuse the 6th rocket correctly so headed home to add the fuse. Thinking that there was no chance of the rocket actually taking off we decided that we could let it of in the back garden. Bearing in mind we have an acre it shouldn't have been to bad. Anyway, the rocket took off with alot of power and looped straight into my neighbours roof about 300m away. It was so powerful that it destroyed 5 or 6 roof tiles and damaged a part of the roof whilst they were in the back garden mowing the lawn.

As you can imagine they were not best pleased. Luckily the guy saw the funny side of it and actually started laughing after the initial anger subsided. He had played with BP when he was younger and had put a whole in his garage door trying to make rockets. Anyway after offering to fix his roof he saw the funny side of it and laughed it off. All I can say was that I was very unlucky for the rocket to fly exactly into his roof but also very lucky that he didn't call the police.

At the end of this I think my lesson has been learned. NEVER think you know what a rocket or BP will do.

Sorry for the language.

I have no problem with competing pyro shops please I welcome anyone that makes my hobby more cheaper. I just don't like people taking the p**s by selling chemicals 5x the cost of anyone else

Correct.

However, I do work in the industry where it is required to make larger batches and the thinking is that you may as well make 1 5kg batch rather than 50 100 gram batches as 100 grams will kill you so anything more is actually less risk as the mixing frequency is reduced.

Wow, what do you use 5kg of FP for? That would make one HELL of a bang.

Edit: Fireworks obviously...................stupid question

No amount of PPE will save you if something goes wrong when working with large amounts of flash.

If you haven't already, have a quick look at the 'consequences' page archived here. It's extremely graphic but really drives the message home.

There's only one way of ensuring nothing goes wrong with large amounts of flash powder and that is by not making it in large amounts!!! Which I don't plan to
