Tell how a plasma ball works and tell what it does, pressure on the globe, and what happens when we put something small and weak on the globe. So when wrote about what did to the plasma ball this is what is written. It was tested the globe and there was a blue line in the ball following my finger. Touched it and it went on my computer and saw a lot of stuff on my computer. Started to read what it said and wrote everything in own words. Noticing that a plasma ball is a high voltage electrode. Plasma Filaments extend from the inner electrode to the outer glass insulator,giving the appearance of multiple constant beams of color. I also found out that the plasma ball was invented by a intelligent person named Nicola Tesla. After his experimentation with high frequency currents in an evacuated glass tube for the purpose of studying high voltage phenomena, but the modern versions were known to be first designed by Bill Parker. Tesla called this invention an insert gas discharge tube. Plasma globes were most popular as novelty items in the 1980 's. Although many variations exist, a plasma lamp is usually a clear glass sphere filled with a mixture of various gases (most commonly neon, sometimes with other noble gases such as argon, xeon and krypton ) at nearly atmospheric pressure. Energy comes from a lower-voltage DC power supply usually connected to mains power, and flows through a high-voltage transformer combined with a high-frequency electronic oscillator circuit which together output a high frequency and high voltage AC to the electrode. Therefore, the circuitry inside the electrode can be considered as a specialized power inverter. The high-frequency high-voltage power, or radio frequency energy, is transmitted into the gas within the globe through an electrode at its center. A much smaller hollow glass orb can also serve as an electrode when it is filled with metal wool or a conducting fluid that is in communication with the transformer output. In this case, the radio-frequency energy is admitted into the larger space by capactive coupling right through the glass. Plasma filaments extend from the inner electrode to the outer glass insulator, giving the appearance of moving tendrils of colored light within the volume of the globe (see corona discharge and electric glow discharge). Some globes have a control knob that varies the amount of power going to the center electrode. At the very lowest setting that will light or "strike" the globe, a single tendril is made. This single tendril's plasma channel engages enough space to transmit this lowest striking energy to the outside world through the glass of the globe. As the power is increased, this single channel's capacity is overwhelmed and a second channel forms, then a third, and so on. The tendrils each compete for a footprint on the inner orb as well. The energies flowing through these are all of the same polarity so they repel each other as like charges: a thin dark boundary surrounds each footprint on the inner electrode. Also tried out some other objects that will maybe can let a lightning strike follow the object that has been tested on. Nothing will work but only metal and a finger. It's like creating your own personal bolt of lightning from the electrode to your finger! This phenomenon occurs because of the conductive properties of the human body. When you touch the glass, you create a discharge path with less resistance than the surrounding glass and gases. So now every time it is tested it is going to be easy to know how a plasma ball works.
