The solid smoke bomb material is flammable and can be lit directly. You can light your smoke bomb using a lighter, preferably one of the long-handled types used for barbeque grills. Only light your smoke bomb in a well-ventilated area, on a surface that won't catch fire. The smoke bomb will burn vigorously (more slowly with a higher percentage of sugar) with a purple flame.
Alternatively, you could place a short length of fuse into the smoke bomb when you pour it, and then light the fuse.
I have a smoke bomb video which shows this tutorial in action, plus what you can expect when you light the smoke bomb. You can adapt the smoke bomb recipe to make a homemade fountain firework, plus there are additional recipes for smoke bombs...
