Plasma Sphere

A plasma sphere is a transparent, globe-shaped device filled with noble gases at low pressure, with a powerful electrode at its center. When powered on, it creates electric filaments or tendrils that extend from the center to the outer glass, demonstrating the behavior of plasma—the fourth state of matter—is a highly energized state of gases with free-moving electrons and ions. The colorful streams respond to touch and change with external influences. Plasma spheres are used for visual effects, educational demonstrations, and scientific research to explore plasma physics and electric fields in an engaging way.
