I've had a tough time finding information on these cuties, no help searching here, nor in rec.pyrotechnics.
The second link does give a little bit of insight but i was wondering if someone else had found a better tutorial.
I actually have no idea of what it is that really burns inside those things... (skylighter says it's a cardboard square soaked in wax, but i don't see how it can burn for 4,5 minutes!)
Thanks, any info is welcome!
