Interactive 6″ Plasma Ball – Purple
Plasma ball with sound activation, light show at your fingertips. The plasma ball operates when voltage is introduced in the miniature Plasma Ball 6 inch Purple and creating an electric field inside the ball. As the electrode is negatively charged, the escaping electrons are introduced into the larger glass ball, where they interact with positively charged ions floating around inside. A concurrent oscillating voltage is introduced, changing the electric field and the path of the electrons, resulting in the tentacles – which, at this point, are invisible – that strike the inside of the larger glass ball.
