The ball is made of high-strength glass filled with inert gas and has a black spherical electrode in the center.After power-on, the oscillating circuit produces a high-frequency voltage electric field. Because the inert gas in the sphere is ionized by the high-frequency electric field, it produces a mysterious color and is very beautiful in the dark.

When you touch the ball with your hand, the distribution of electric fields and electric fields around the ball is no longer homogeneous and symmetrical, so the light is warped and twisted around your finger and dances as you move your finger.

The plasma ball light also has a sound sensing function, which can change the light beam according to the music level of the sound or music. It is ideal for bars, nightclubs etc. and can bring unexpected mystical effects.Of course, it's also a good gift for your friends.
