Thanks Guys,

Hopefully my parents will come round to the idea now i have the basic facts. I have two motors a 1/4 hp from a washing machine and a 1/3 hp which looks like it came from a cement mixer its huge! i think ill go with that one.

EDIT: Its worked a treat, Mission accomplished!

Slightly off topic but, my parents say that the electric meter goes awal! when the washing machines turned on so does using the washing machine motor for a ball mill have the same effect and has anyone noticed any changes in the electricity bill since they got a ball mill, without including the effects of the "CREDIT CRUNCH".

Thanks Ryan,

Ok got it, For a simple comet what leaves the longest thickest tail chrysanthemum #6,
chrysanthemum #8 or Tiger Tail ?

If i buy some ceramic media am i better off buying Balls or Cylinders or is there no difference?

Thanks Guys,

Looks like ill start with extra charcoal first, then like you say start adding effects when the motors become more reliable. I made my first serious rocket on Sunday night. Even i was impressed with its performance. My parents and aunty and uncle where watching and expected a few sparks from a paper tube but it was brill, went higher than most rockets we buy and had a the lift off sound to match, put the biggest grin ever on my face.

Does the comet on top of the shell act as a delay or is the shell ignigted from the motor?
