Well the rockets in this case are fireworks. I was probably too vague with my description in the term rockets. I was under the assumption that it took only a small ammount of amperage to heat a piece of nichrome wire to ignite a fuse. I ordered a sample pack of various gauges as small as 45g and as ...
