zapper + water enhancements

I was considering doing something similar [a 'bubble' area of effect] if the zapper is discharged in water.

So, it could be a cool enhancement to make zapper rays electrify water, either using some "explode" radius, or via (a cascade of) frag rays. Either way, we should make sure the effect is limited to the water volume (e.g. "extinguish" or reflect rays hitting the water surface?). I guess using the zapper while swimming should be a guaranteed and rather painful self-hit.
