Plasma globe

A plasma globe is a decorative glass sphere filled with inert gases and a central electrode. When electricity energizes the electrode, it creates colorful tendrils of plasma—ionized gas filaments—that extend toward the glass's inner surface. These filaments respond dynamically to touch, changing shape due to the electric field and the conductivity of your body. The globe showcases the beauty of plasma—the fourth state of matter—by demonstrating how ionized gases conduct electricity and produce vibrant visual effects. It combines science and art, illustrating principles of electromagnetism and plasma physics in a captivating, interactive display.
