So what exactly is a plasma ball? Before we can answer that, let's first take a look at what plasma is. Although it sounds a bit mysterious, plasma is actually the most common form of matter in the universe! It's even more common than solids, liquids, and gases!
The electrode at the center of a plasma ball emits a high-frequency, high-voltage altering electric current. This current flows through the plasma filaments to create colorful tendrils of light.
This phenomenon occurs because of the conductive properties of the human body. When you touch the glass, you create a discharge path with less resistance than the surrounding glass and gases.
3 DIFFERENT SIZES
As a way to compare:
- 4 in - 10 cm is roughly as big as a tennis ball.
- 6 in - 15 cm is roughly the size of a volleyball.
- 8 in - 20 cm is roughly the size of a basketball.
