The visual effect makes it seem as though current is passing directly through the glass to follow the touch. In practice, the phenomenon is explained by capacitive coupling rather than conduction.

Knowing About Universe on Instagram: "The video shows a plasma globe where vivid purple filaments dance and bend toward a hand placed on the glass, creating the illusion that electricity is passing straight through it. This often surprises viewers, since glass is known as an electrical insulator. In reality, the glass does not conduct electricity. Instead, the globe uses high-frequency alternating current, which allows capacitive coupling. Your hand alters the electric field outside the glass, a
