A Lichtenberg figure (German Lichtenberg-Figuren), or Lichtenberg dust figure, is a branching electric discharge that sometimes appears on the surface or in the interior of insulating materials. Lichtenberg figures are often associated with the progressive deterioration of high voltage components and equipment. The study of planar Lichtenberg figures along insulating surfaces and 3D electrical trees within insulating materials often provides engineers with valuable insights for improving the long-term reliability of high-voltage equipment. Lichtenberg figures are now known to occur on or within solids, liquids, and gases during electrical breakdown. Lichtenberg figures are natural phenomena which exhibit fractal properties.

What Happens When You're Struck By Lightning? | The Human Body
Getting stuck by lightning is rough. It can burn hotter than the sun, scar your body, and even blow off your clothes. Even worse, it kills about 47 Americans per year. Although 90% of those struck survive, it's still worth knowing how to avoid getting a heavy dose of sky electricity. Fol

Lichtenberg High Voltage Wood Burning on a CYLINDER of wood
Using 2000 volts of electricity I did some Lichtenberg high voltage burning on a cylinder of wood. I used two tube clamps to attach the wires so that electrical contact was even around the ends of the cylinder.
