Wiring????

I'm making a spud gun, but I want two ignition sources with series wiring.

BUT I always get confused between parallel and series wiring... so I made 2 diagrams. Which one would be a series?

Thank you,
Ryan-John!

Neither.

Go from + on the battery to + on coupling one. From - on coupling one to + on coupling two. From - on coupling two to - on the battery

That would be series, but I do not know if that is the correct way to wire a spud gun. lol

Ok followed your instructions and got this! See the screws? Well there needs to be a spark to ignite the propellant inbetween them at the same time.

that last drawing would be series.
I assume you are gonna put a switch in, and when you close the switch both sparks should happen at exactly the same instant.

The voltage and amperage of your battery needs to be sized so that both are twice what is needed at each coupling.

Would a piezoelectric grill starter do? ... probably not... or should I use a 9-volt battery? and Where should I put the switch? on the (-) or (+) wire?

Thanks for the help thus far!

it does not matter if you put the switch on the + or -

As for the rest I have no idea. I do not know what voltage/amperage etc it takes to fire the gun.

Use a coil out of an old car. You can get them from a junk yard for 5 bucks (or maybe cheaper). You can even find 6 volt coils around if you ask.
