A plasma ball, plasma globe, or plasma lamp is a clear glass container filled with noble gases, usually a mixture of neon, krypton, and xenon, that has a high-voltage electrode in the center of the container.

High voltage is applied to an electrode in the center of the globe. This high voltage must be high frequency AC or high frequency pulsating DC in order for any current to get through the glass of the globe and surrounding air by capacitive coupling.

Apr 3, 2013 · The Plasma Globe is an engaging and safe tool for studying high voltages and the electric field. Here are our top 10 demonstrations to perform with the Plasma Globe.

Apr 2, 2024 · The Neon Globe would be the closest thing in terms of physical shape and size, so once we iron out the circuit. With a few more starting volts, you could easily replicate this. Initially several of the people who RE-DISCOVERED this in the mid-2020s, found it by accident.

A Plasma Globe consists of a glass container of gas at reduced pressure with a high voltage source in the center that produces a charge difference between the center tower and the inside surface of the outer glass wall.

Nov 3, 2016 · We had read about an effect that can be observed under high voltage power lines—namely, that fluorescent tubes will actually light up when held in your hand. That same high voltage effect can be shown using a Plasma Globe. In our Plasma Globe Experiment Kit (PLS-110), we provide you with a small 9” fluorescent tube. If you hold one end of ...

Jan 22, 2020 · Made a plasma ball from a plastic wine glass filled with about 15kPa of argon. Works some with air at lower pressure, around 5kPa. Experimented with argon/helium mixtures, but plain argon was the brightest. Don't have neon nor xenon around (due to expense), the normal gasses inside plasma balls.

Aug 28, 2018 · A plasma globe or plasma lamp (also called plasma ball, dome, sphere, tube or orb, depending on shape) is a clear glass container filled with a mixture of various noble gases with a high-voltage electrode in the center of the container.When voltage is applied, a plasma is formed within the container.

Here is a nearly pure neon globe. It likes 16 kHz for its best look. By placing one's hand in the vicinity of the globe, streamers trace toward the hand. You can see the outline of the hand in Red on the top of the globe as the concentration of electrical energy lights up the Neon gas.

Mar 23, 2004 · The high voltage breaks down the gas, and the high frequency gets the current through the glass of the globe and into the surrounding air by capacitive coupling. Typical voltages are around a few thousand volts for most commercial plasma globes, sometimes around 10,000 volts for some homebrew ones, or the larger commercial ones.
