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.  Small tendrils may also 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.

Spheres are easily supported by a napkin ring (provided) and brilliantly illuminated by one of our multicolor/color changing or white LED bases. The sphere optically magnifies portions of the discharges, further  enhancing their beauty and detail.
Although the physics and technology involved in creating these are complex, the results are simple: they' are incredible!  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" Lichtenberg Magnabrites® (light gathering magnifiers with internal Lichtenberg Figures), and our 2.0"  spheres.

Note: Because of self-focusing effects, spherical specimens should not be left unattended in direct sunlight or illuminated by nearby halogen lights, since the lensing action of the sphere may damage or ignite nearby objects.
