i know hooked up to DC this is called electrolysis , it breaks the water down, one side makes HYDROGEN, and the other make pure oxygen. hooked to ac i imagine the same thing just alternates side very fast. so i could be wrong but im pretty surer this would be creating HHO or hydrogen Hydrogen Oxygen, or broken down H20. so add a little bomb with that electrocution.
The lighter was explosive once it was hit by anything solid or even striking the ground with the lighter it break and explode. The really powerful slingshot is when used with signicant accuracy at a long distance
