When it is operated, the gas inside is excited electromagnetically and random radiations occur in colors determined according to the gas mixture. Plasma Sphere is a device that contains a low-pressure gas mixture and operates with high-frequency variable current. The small sphere in the middle serves as an electrode. When the device is turned on, plasma particles begin to be transmitted from the small sphere in the center to the inner surface of the glass sphere outside, in the direction of the electric field lines and in the form of colored radiation. When you touch the sphere with your hand, it affects the high-frequency electric field and produces single radiation from the small sphere in the center to where you touch the outer glass sphere. This is because the glass acts as a dielectric within the capacitor, manually shaping the ionized gas. Did you know? The Sun, the source of heat and light of our world, is also a giant square of plasma. Touch the glass ball while the device is running. Observe what happens?
