plasma globes

A plasma globe is a decorative device that creates colorful streams of light inside a glass sphere. It contains a low-pressure gas and a high-voltage electrode at its center. When electricity flows through the electrode, it ionizes the gas, forming plasma. This plasma forms visible, glowing tendrils that arc toward your fingers when you touch the glass, creating a fascinating interaction. Plasma globes are often used for educational purposes in science demonstrations, as they visually illustrate concepts of electricity, plasma, and electromagnetic fields in an engaging way.
