While Plasma often relies on the element of Neon to achieve the desired effects, other gases are also utilized to bring about desired effects, colors, and behavior of plasma. Sometimes referred to as "the fourth state of matter," plasma is group of charged particles that are good conductors of electricity and easily affected by a magnetic field. The types of gases frequently used to create plasma for art include helium, xenon, argon, krypton, and neon. These combinations of gases, along with voltage and size of the containment vessel, will influence the color and character of the plasma that audiences will see.
