Well, newyearseve pyro was a succes.
In recent tests some of the rockets exploded on the launchpad, so I wasn't confident that all rockets would work properly, I decided to make shells instead.
All shells were launced from fibreglass tubes with 20 gram granulated BP that was ballmilled for 3 hours.
Liftcups were easily made from paper drinking cups,the quickmatch was commercial chinese(5 strands).
For the delay I used spolettes with about 2 sec. delay, the quickmatch was connected to the spolettes directly to ensure ignition.
I used 5:1 Bp/ricehulls and 2 grams of perchlorate/benzoate wistle as breakcharge.
All shells functioned perfectly and exploded at apogee.
The blue,purple,gold streamer and silver flitter stars all worked exelent, the ruby red and emerald green stars were a disapointment, not the nice deep colours I expected.
Maybe it was the magnalium I used it may have been to coarce.
All in all it was a very succesfull newyears eve.
"Any society that would give up a little liberty to gain a little security will deserve neither and lose both."
Nice stuff anyway. The cheapest stars can be more fun than expensive perc ones etc sometimes!
