Lichtenberg figure
Videos
A Lichtenberg figure, 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 asso
Modern 3D Lichtenberg figures or "electrical treeing" in a block of clear acrylic, created by irradiating the block with an electron beam. Actual size: 80 mm × 80 mm × 50 mm (3 in × 3 in × 2 in)
Lichtenberg figures are generated by a sliding spark discharge on the flask with a mixture of gases. Structural differences between the "positive" and "negative" figures can be observed.
The slight branching redness traveling up this person's leg was created by current from a nearby lightning strike.

Fulgurites, commonly called "fossilized lightning", are natural tubes, clumps, or masses of sintered, vitrified, or fused soil, sand, rock, organic debris and other sediments that sometimes form when

…large Lichtenberg figure in grass surrounding the point struck. These are sometimes found on golf courses or in grassy meadows. Branching root-shaped "fulgurite" mineral deposits may also be created as sand and soil are fused into glassy tubes by the intense ionizing electrical current, an effect often seen in…
