Effect of humidity on spark gap

Post questions and info about combustion (flammable vapor) powered launchers here. This includes discussion about fuels, ratios, ignition systems and anything else relevant to launchers powered by igniting things like hairspray or propane.

My experience with igniters is the sharper the point the stronger the spark regardless of gap. My preference is #6x32 stainless machine screws, tapered to a point, gapped about 1/16" for dual igniters. I know you are metric up there, however this may translate for you.

I for one will be waiting to hear the results of your tests on various combinations of multiple sparks.
