Our Halloween Skull Crystal Globe Plasma lighting Ball has the Appearance of high-strength glass spherical shell, filled with inert gas thin inner sphere, the central spherical glass balls with a black electrode.
Have a ball at the bottom of the oscillator circuit board by a power converter that converts 12V DC into a high-pressure low-pressure high-frequency voltage applied to the electrode.
Power, the electric field oscillating circuit generates a high-frequency voltage, since the inner ball rarefied gas ionization by high-frequency electric field and shine, produce mystery.
Some linear light glow occurs, colorful, radiant, very nice in the dark.
When the hand (people connected to earth) touches the ball, the ball around the field, the potential distribution is no longer symmetrical, so that the light becomes brighter place around the finger, hand touch along the arc generated by the movement of swimming twist, move and dance with your fingers.
