Napalm and sticky napalm, small batches, just to do it as a yute, not thermite. I had magnesium, but no barium peroxide.
BTW, kerosene and Palmolive doesn't burn worth a damn, but it makes a great hand cleaner.
My limited experience with thermite suggests couple of things. One is that it’s quite fiddly, and getting the ingredients powdered finely enough and mixed thoroughly enough is not trivial. Not impossible, but not trivial either. It also is a bit difficult to get started, but once started it really wants to burn to completion. So I see what you’re thinking. I’d have to experiment with it, though, to see if the doped fabric has a thermite reaction or just burns.
Never played with napalm.
