Stoneridge Engineering is THE Source
for Rare and Beautiful Lichtenberg Figures!

Style 29 - Two inch "Ball Lightning" Spheres

We start with beautifully polished water-clear acrylic spheres. We then irradiate them with an electron beam while simultaneously rotating them in order to form a spherically shaped region of internal charge. When discharged, the results are simply stunning. The lightning-like internal 3D discharges branch inward from a single external root,  mostly following the curvature of the sphere. Sometimes tendrils also head directly inwards toward the center of the sphere.  When illuminated from below, various display effects can be obtained depending upon how the sphere is oriented for viewing.  For example, with the discharge point positioned on the side opposite to the viewer, one gets the illusion of a completely imbedded discharge that seems to originate from the very center of the sphere, sort of like an exquisitely detailed plasma ball. Rotating the sphere 90 degrees brings out long curving branched discharges that follow the outer curvature of the sphere. It only seemed appropriate to call these beautiful sculptures "Ball Lightning" Spheres.

Each Ball Lightning Sphere is provided with a wooden or acrylic ring, or a dimpled acrylic block (provided at no charge). Spheres are best illuminated from below by one of our multicolor or white LED bases. Optical magnification effects even further enhance the beauty and detail of the internal discharges!

Although the technology involved in creating these figures is complex, the results are simple: they're incredible!  Because of the physics of the process, most specimens will have asymmetric discharge patterns. Each figure is provided with a one-page explanation about what Lichtenberg Figures are and how they are created. If you like these specimens, you'll also want to see our incredible 2.5" and 3.5" diameter Magnabrites® (light gathering magnifiers with internal Lichtenberg Figures) and our magnificent 3" Ball Lightning spheres.

Please note: Spherical specimens should not be left in direct sunlight or illuminated by nearby halogen lights since the sphere focuses light and may cause heating and damage to nearby objects.
