Styles 47 and 30 - Spectacular 2.5 and 3 Inch "Ball Lightning" Spheres

We begin with highly polished water-clear acrylic contact juggling spheres. We then rotate them while irradiating them with a high-energy electron beam to create a highly-charged spherical region inside. When we discharge them, the results are simply stunning. The lightning-like 3D discharges branch inward from a single external root,  mostly following the outer curve of the sphere.  On a few specimens, small tendrils may head towards the center of the sphere. 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 the viewer, one gets the illusion of a completely embedded discharge that seems to originate from the very center of the sphere - similar to a freeze-frame of an exquisitely detailed plasma globe. Rotating the sphere 90 degrees results in long branching discharges that follow the outer curvature of the sphere. It only seemed appropriate to call these beautiful sculptures "Ball Lightning" Spheres. Due to the complex physics of the discharge growth process, discharges may not be symmetrically distributed within the sphere.

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 asymmetrical 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, you'll also want to check out the incredible 2.5" and 3.5"  Magnabrites® (light gathering magnifiers with internal Lichtenberg Figures), and our 2.0"  spheres.

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