A plasma ball, also known as a plasma globe, is a glass sphere filled with a mixture of gases, typically neon and xenon. When an electrical current is applied to the sphere, the gases inside become ionized and create a glowing plasma. Plasma balls are often used as decorative objects or as educational tools to demonstrate the principles of electricity and plasma physics.
The best plasma balls are made from high-quality materials and have a long lifespan. They also produce a bright and even glow, and are free of defects such as bubbles or scratches. Some plasma balls also have additional features, such as the ability to change color or respond to music.
