Small on size, big on science. In a 3-inch sphere, watch as tiny plasma
filaments branch out from the central electrode to where you touch the glass
creating fascinating beams of coloured light. The Science Museum Mini Plasma
Ball also reacts to sound. Sit it on your desk or shelf and watch this
scientific energy lamp create flashes of miniature lightning. Part of the
Science Museum innovative lighting range.---Full Product Description---Promotes
STEM learning. The plasma ball is a form of Tesla Coil. The glass sphere has
most of its air replaced with 3 noble gases - typically Neon, Argon and Xenon -
and an alternating current electrode is placed at the centre. When voltage is
applied, plasma filaments extend from the electrode and flow towards the outer
glass insulator in a bid to reach the earth. If a fingertip is placed on the
glass the energy moves toward it, because the human body provides a more
conductive discharge path.
