Fireworks in space
As I sat contemplating my navel the other night I wondered, if an astronaught managed to anchor a firework rocket down on the moon, lit the touchpaper then stood back to a safe distance, what would happen? As there is zero gravity would the rocket fly off, stay static, bury itself of simple explode. Would it explode at all? I'm really curious now and finding hard to sleep!!! Thanks folks

Well there is not zero gravity for a start! Ignoring for a minute the lack of oxygen and the fuse was some how allowed to burn down, the rocket would take off as on Earth and travel 6 times higher before falling back. It would not acheive sufficient velocity to escape the moon's gravity. Probably the lack of oxygen though would make it a very unspectacular event.
The rocket would take off and burst with stars, dependant on the stars loaded into the rocket.
Some firework effects have a positive oxygen balance. In other words, they rely almost entirely on the oxygen in the oxidiser present in the mixture.
Some have a negative oxygen balance and rely on the presence of atmospheric oxygen for their effect.
For example the willow effects that just look like tendrils of sparks hanging in the air, are fine particles of charcoal or aluminium that rely on atmospheric oxygen to continue glowing after the initial burst.
Plain coloured stars such as reds and greens would be likely to burn as on earth, with the addition of a bit more oxidiser in the mixture..
