Beautiful glow

Beautiful Glow - Customized Science Museum Exhibitions, Campus Community Science Popularization Equipment, Source Manufacturer of Science Exhibitions Description and Introduction of Scientific Principles:

This exhibition item introduces the phenomenon and basic principles of glow discharge to the audience through the demonstration of a glowing sphere. Exhibition items mainly consist of a table body, glow balls, glow discs, etc. The center of the disc is equipped with high-frequency and high-voltage electrodes, and the disc is filled with low-pressure inert gas. After the high-voltage electrode is energized, due to the strong electric field and the thin inert gas, it is ionized and excited to produce a beautiful glow. Helium in inert gases emits blue light, argon emits light purple light, and neon emits orange red light. When the hand is placed on the glow disc, a discharge channel is formed between the hand and the electrode, and the glow in this area becomes even brighter. As the finger moves on the glow disc, the discharge channel moves accordingly.
