Glow Ball

When the glow ball is touched by hand, the human body becomes another electrode, and the electric field and potential distribution around the ball are no longer uniform and symmetrical. Since the resistance of the human body is much smaller than the resistance of the surrounding air, the potential of the fingers is relatively low, which is more conducive to the formation of potential drop from the center of the sphere. The current glow mainly converges at the fingertips, making the glow become more concentrated around the fingers. In order to be bright, the arc produced will swim and twist along with the touch of the hand, as if dancing with the movement of the fingers. Glow balls are often used as a popular science display device in science and technology museums, schools and other places to help people intuitively understand physical concepts such as gas discharge and electric fields, and to demonstrate the charm of science and technology.
