    Rocket launch system

    Hello folks, I am making an launch mechanism which will put fire in a match which will light my rocket engine. How many amperes do I need o heat enough a wire with the diameter which is just a bit bigger than a strand of hair (the voltage is 9 volts from a alkaline battery) ?

    If you already have the wire and the batteries, what result do you obtain:
    * with just one battery
    * with two batteries in parallel
    * with two batteries in series
