HELP! I am a total electronics rookie, but have been asked to produce a prop for a stage production which can only be created electronically. I need to created a simple system by which it will be possible to create a spark/flash at the push of a button, sufficient to ignite a small ball of Magician's Flash Cotton (which is essentially cotton wool soaked in parrafin and other flamables and then dried). Someone has suggested a 9v battery and resistor setup, but I have no idea what to use or how to start - HELP ME I BEG OF YOU!!!
