Hopefully this question hasn't been asked here before, I did a search and it seems everyone else is asking much more practical questions. Anyway...The Situation:
I'm modifying a Nerf gun (this one for anyone who's curious):
http://3.bp.blogspot.com/_ynWOAg4YQB0/Sc9SGX8EzZI/AAAAAAAAAN0/mQTCVkYJS34/s400/Nerf_Maverick_01.JPG
in a black and blue/electricity theme and one of the components I want to add is a small, clear, elongated dome on the top of the gun in front of the grey slider with two poles under it that, when the slider is pulled all the way back, have an arc generated between them to make it look like each dart is being charged up before being fired. The plan for how to achieve this is to put a small momentary push-button switch behind the plunger inside the gun that will be pushed when the slider pulls the plunger all the way back, connected by wire to one pole and have the other pole connected by wire to a power supply (it looks like there's enough space for one inside the handle of the gun) that's connected back to the switch. The circuit would be completed when the button is pushed and the arc jumps between the poles under the dome. I put a fairly sizable crack in the dome both for cosmetic reasons and because I know if a perfect seal were made the air inside would ionize too much after a few arcs to make any more. Obviously this whole circuit is completely useless for anything other than making a thing that does cool stuff look like it does other cool stuff it doesn't really do, but I know that even just sustaining the arc drains voltage out of the power supply so I'm working on a hatch for the butt of the gun so that the power supply can be removed and/or replaced if need be.The Questions (because I'm a liar like that and I thought you'd be more likely to enter the thread for one question than you would for two plus a lengthy explanation. Ha! Gotcha!):
What kind of power supply would I need to generate the arc between the poles?
Is there any part of this plan that you could foresee failing that I'm not seeing?Other (Possibly) Useful Information:
I know the math as far as voltage/resistance/current and whatnot, but as I said before everything I've found so far has either been overly complicated or at a completely different scale than I'm working on. My main areas of interest/study are art, music, particle physics and astronomy so this is probably as complex a wiring job as I'll ever take on. I already have a very healthy respect for the power of electricity so I'm taking every precaution I can think of but if I'm missing anything, please let me know.Any help with this would be appreciated but either way, thanks for your time.

P.S. I've been taking pictures and notes all throughout the process of modifying the gun so if anyone here is interested, when it's done I'll be able to post anything from just a picture or video (I'm planning on filming a short video of its "electrical capabilities" enhanced with some after-effects just to extend the project a bit and add in yet another tool or two that I don't work with that much) of it finished to a full report of exactly what I did to it (think of it as the idiot's version of a paper on a scientific experiment) as the whole project is going up on at least one other forum so I can easily post any or all of it here too. Let me know if any of you are interested in seeing any of that regardless of whether or not you have an answer to any of the questions posed above.
