A couple years ago I phoned some garden shop here in Calgary and asked the guy if he had any potassium nitrate, he told me he did. I went down to get some of it, told the guy it was for a science project, and he gave me 5 pounds of it for FREE. I still have lot's of it left.
Also you don't need to cook the stuff, you can just make a 60/40 mix of KNO3 and sugar respectively, stick a fuse-or some other way of lighting it-into the mix, and light it up.
You can also make fuses by taking some of your 60/40 mix, throw in some water until you have a nice kinda pasty crap, and then soak some wool in it. Let it dry over night, and you'll have a nice cheap fuse.
