in some azure bombs or any type of azure bomb, there is a ingredient named SPRK (LIGH) which explodes in a big mass of string made out of lightning and spreading everywhere, once i tried to set iron'stype to spark and set sparks ctype to ligh, it just decayed without a trace.
you can grab a very high life sprk by using prop tool and then ctype (LIGH) and shove protons in the sprk and it should explode into lightning going--->this way
