What we’re seeing is Lichtenberg Figures form from an electron beam getting zapped into an acrylic prism. The electric trail of the lightning strike is so badass. It’s like trapping a lightning bolt in a glass box forever, a force of nature on display.
Lichtenberg figures (sometimes called lightning trees) sometimes occur when an electrical charge is introduced to an insulating material, representing the branching electrical discharges. They can occur in resin, glass, grassy fields, and, if you're unlucky enough to be struck by lightning, human skin.
Lichtenberg figures are fantastic; they perfectly display branching electric charges that occur within, or on the surface of, certain insulating materials. Sure, that may sound like a whole load of boring, but check the image above to see why you are wrong—they look amazing. Popsci is hosting a video that shows you…
