Stranger learn on Instagram: "The post features a close-up clip of a plasma globe where bright purple filaments bend and concentrate toward a hand placed on the glass, prompting surprise over how electricity appears to react through an insulating surface. 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. The globe uses high-frequency alternating curre

Crazy Master on Instagram: "The post showcases a plasma globe video where purple plasma filaments respond to hand touches on the glass surface, prompting the author's surprise at glass seemingly conducting electricity. In reality, glass insulates direct current but permits capacitive coupling with high-frequency alternating current, allowing plasma streams to follow the electric field without electrons crossing the glass.
