Captured Lightning – Embeded As Art


Here is a pretty cool art form, captured lightning. They capture it on plexiglass. VIDEO->

The interior of an 18″ square x 1″ piece of Plexiglas was charged to 2.2 million volts (MV) using a 5 MV particle accelerator. A layer of excess electrons become trapped deep inside, When discharged, the excess charge escaped with a bright flash and a loud bang. The hot, lightning-like discharge created thousands of microscopic fractures inside the acrylic, resulting in a branching “Captured Lightning” sculpture (or Lichtenberg Figure).
