There is lots that can be done with just KNO3, charcoal, sulfur and dextrin, like making rockets, fountains and wheels (maybe with a few additional metal powders like titanium, or iron). Once you perfect these you will be ready and skilled enough to start using perchlorates and metals safely, and that is how you progress.
Have a look at what other people have done and learn from other professional websites (pyroguide and skylighter both have good info)

my personal favourite is a small shell (2"), on the top of a black powder rocket, filled with either Winokur #20 or chrysanthemum 8 stars and about 5g of fast granular black powder. Even after seeing countless rockets of my own go up, I'm still incredibly happy when they do, also perfecting your design will take years, at the moment I'm getting 2kg of force from 8g of rocket propellant, and when they don't have a header you can just hear a huge whoosh and when you look its gone... No idea where...
you'll soon find your own style and techniques...

Capacity in Newton Seconds?
APCP?

I wish it was APCP. I'm making a spindle for that soon though, but its actually 60:30:10 black powder, and sustained for under 0.2 seconds (if I remember rightly,) this is on a home-made spindle. I can send you the video of the scales if you want to see...
Just interested. Very short impulse. I believe your results. APCP has some interesting issues, such as getting the chamber pressure up (never done it myself, just read about what the rocket boys do to initiate the motors).

hi, id forget the extra chems for a while and invest in a few pyro books, so you fully understand the chemicals before you start to use them, ie any possible incompatibilities mixing, dry or wet ie "stars"cheers for the fountain and rocket ideas, i'll try them soon
any ideas of chemicals i should get for some more basic pyro?
thanks
you need to approach this hobby in a professional manner after you have reserched the chems you have, and any future chems on your wish list, you'll be ready to try some basic formula (usally in the same book) ie THOMAS KENTISH, WEINGART ect
there's not much point collecting chems at random at asking "what do i do with them?" regards chris

Lancaster's and Shimizu's books and their collaborative works are more up to date with materials and techniques.

there a great resource of techniques that at least get you going in the right direction as opposed to " i got chems what now?".
the kentish book is a good read,have you seen it?

You stand a chance of safely making something pretty IF you have read some books, otherwise you stand a chance of making a blood covered mess (your blood )
