15“ x 20“ x 2“ Captured Lightning (Lichtenberg figure) sculpture being discharged inside a large slab of clear acrylic (Plexiglas/Perspex). This specimen was passed through the electron beam one time, flipped 180 degrees, and run through the beam again to create two separate charged regions.

Before being discharged, the estimated initial potential of the internal charged reg
