Is it possible to make a sparking taser?

So, there are a lot of people posting articles on how to make tasers, most of these only spark if they touch something conductive. I would like to ask, how can you make the current jump between the two wires without touching something conductive?

thanks


Most commercial tasers have two sets of prongs. The ones on the very front that you prod a person with, and a second set farther back that are closer together. The more closely spaced ones are close enough that an arc jumps between them, but internally they are connected to the front prongs.

If you contruct yours in a similar manner, you should be able to achieve the same effect.
