Plasma Energy Ball — Electrostatic Physics Display (6-Inch)

Watch electricity come alive at your fingertips.

The electrode at the center drives a high-frequency, high-voltage AC field. The low-pressure gas (neon, argon, or xenon mixture) ionizes along field lines between the electrode and the glass sphere, producing plasma filaments. Touch the glass to change the local boundary condition — the filament concentrates toward your finger because your body acts as a ground path. The filaments are real plasma: ionized gas channeled by electromagnetic field geometry, the same physics governing fusion reactors and lightning.

Different gas mixtures produce different colors: neon gives red-orange, argon gives violet-blue, xenon gives white-violet. The color is a direct readout of the emission spectrum of the ionized atoms.
