The Remote Control Glow Discharge (RGDX) is a plasma you can control from the comfort of your browser. You have control of the entire experiment, including the gas pressure inside the tube, the voltage produced by the power supply that makes the plasma and the strength of an electromagnet surrounding the plasma. You can perform experiments from any computer anywhere in the world!

In 2002, we began developing plasma sources for educational purposes, and one of our devices won second place in the national Apparatus Competition(Link is external) sponsored by the American Association of Physics Teachers. In 2003, we began controlling our plasma sources by computer for a plasma exhibit in a science museum. This progression led to remote control of a plasma from any location by anyone with an internet connection. This type of control could serve as an experimental component of an online physics class or for a school that typically does not have plasma physics equipment.
