You can LICHTENBERG my balls....

The Lichtenberg Figure are the jagged branches of an electrical discharge usually through materials surrounding high voltage conduits.  But not just in electrical insulation but other places in nature.

Obviously the most common example of what it looks like are lightning bolts. But even less common are "lightning flowers" which are the markings left behind on lightning strike victims. They are caused by ruptured capillaries under the skin that branch out from the location of the strike.
