BIOHAZARD

Hi-
I made some fountains, roman candles etc. and made some BP rockets but they were crap because I used a screwdriver to punch a hole in the end-so would it be better if I drilled a hole straight down?
and when you've pressed the BP in your rocket and pressed the clay plug on-is it safe to use a metal drill to drill a hole for the fuse?
Thanks

Does anyone know of a decent tutorial that tells u how to make a roman candle?-Diagram!!
Thanks

Hi-
I found a recipe for a star on this website
but I am pretty new so what do I do when the star mix has dried? Do I put it into tubes with fuses or what?
Thanks

Here's a formula for a gerb or whatever they are called that I discovered recently:


/\ ...../\ <----3 mm choke
/.........\
/.........\
/.........\ <----Black Powder 64
/.........\ Potassium Nitrate 8
/.........\ Sulphur 8
/.........\ Iron powder 20
/.........\
/.........\
/.........\
/.........\<----Tube 230*18*10mm bore
/.........\
/////\\\\\<----Wooden Plug

Needs to preferably be pressed and I think instead of the Iron you might be able to use charcoal for gold sparks but not sure?For the choke preferably use clay.
Thanks
