How can i generate an electric arc? Answered

It should be simple , easy and have availability.


Search instructables for "Plasma speaker". You can generate an electric arc, AND listen to your music too!

Use a disposable camera flash transformer to power a cockcroft walton voltage multiplier. You can easily get around 1/8inch arcs.

Car Battery and a couple of carbon rods.

I'm assuming you want to make a big spark

You can pull apart a microwave. That link shows you how to do it and shows some arcs in a video.
