LICHTENBERG FIGURE 😱

Lichtenberg figure
This is an example of what is called a Lichtenberg figure, it occurs when an electric charge, such as lightning, strikes a type of material and becomes trapped. The material can be made of any type of insulating substance, such as glass or acrylic. By nature, insulators are poor conductors of electricity, so how do you make them host an electrical charge as powerful as lightning? The simple but counterintuitive answer is that you turn them from a bad handler into a good handler. To discharge electrons inside glass or acrylic, you must first insert charged particles into the material through a process called irradiation..this creates the same conditions that lead to a lightning strike: when electrons from the cathode ray encounter the charged portions of the insulating material, those portions instantly become electrically conductive and you get a miniature, but powerful lightning bolt.
