A Plasma Globe (also called a plasma lamp, plasma ball, plasma tube, plasma orb, plasma-dome, or plasma sphere) are glass spheres that contain noble gases and a high voltage electrode at the center of the sphere. The plasma globe was first made by Nikola Tesla use corona and electric glow discharges to create the blue and purple lights in the globe. Corona discharge is caused by the ionization if a fluid surrounding and electrically charged conductor. Electric glow discharge is caused by the passage of high voltage electrical current flowing through low-pressure gas.
What effects does the plasma ball have when coming into contact with other objects; what effects do the objects have on the plasma ball? What are the practical applications of the plasma ball's effect?
