Atom Fireworks

Hi Sparky

 Horsetail shells are not always cylinder, in fact the only ones I have seen/used are spherical just like a normal shell. They put enough burst in there to crack the shell open and then momentum and gravity do the rest. If you fire a horse tail shell vertically it doesn't produce the horse tail effect, more of a slim golden waterfall, they have to fired on an angle to produce the effect.

 The star comps in them I would imagine are just willow, d1 etc something with a long hang time and a long duration. A falling leaf effect is far from the Horse Tails effect, falling leafs are 1 solid object ( the star ) falling to the ground with no tail, obviously many of these stars but still not tail.

Looking at what some of the bigger companies have been charging I would guess between £160 and £200 

Thats reasonable, will certainly send one of us on it.

Me too, infact depending on price two of us!

Great. I'll keep it with my UK Rocketry Association card in the wallet. 

 Is this incase the Law catch you testing your rockets ha ha, good plan, I can see it adding merit to your case and proof you are not a mad man, infact a sensible practitioner of pyrotechnics!

Tis a good suject this, by law there is only one answer my freind and that is fuse on the display site. In reality I doubt very much the teams doing very large pyro-musical comps will be fusing everything up on the day.

Static is a worry but no where near as realistic as friction/crush. IF I were to fuse before hand then my method choice would be inserting a strand or two of black match into the igniter housing and then pulling the " head " into it to secure it in place. Doing this on its own is safe because the worst case scenario is that it pops and a little bit of black match burn ( providing you are in a safe environment for this to happen). The you would insert the full igniter head including housing into the QM leader and tape it up.

For the most part it is probably best getting on site an hour or so early to fuse there and then, rather than risk transporting a fused article which will make that item illegal to transport anyway as you have modified it.

Just my thoughts on it anyway, look forward to hearing others.
