For this experiment, you'll need
• Plasma Lamp
• Fluorescent Bulb.

Procedure
• Firstly, switch on the plasma light.
• Take a fluorescent Lamp.
• Bring it near the glowing plasma light.
• Now, observe what happens.
• Notice that as the fluorescent bulb is brought nearer to the plasma lamp, it glows.
Explanation:
A plasma lamp is a clear glass filled with a mixture of various noble gases with a high-voltage electrode in the center of the sphere. Plasma filament extends from the inner electrode to the outer glass insulator, giving the appearance of multiple constant beams of colored light.
The plasma lamp emits high frequency current and hence you can see lot of magic sparks in it.
A fluorescent lamp or fluorescent tube is a gas-discharge lamp that uses electricity to excite Mercury vapor in it.
When the fluorescent bulb is bought near the glowing plasma lamp, the high frequency current reacts with the Mercury present in the fluorescent lamp. The excited Mercury atoms produce short-wave ultraviolet light that then causes a phosphor to fluoresce, producing visible light. A fluorescent lamp converts electrical power into useful light much more efficiently than incandescent lamps.
