Plasma Balls

Zone D: Tempe campus

Electrons are tiny, charged particles that surround all atoms which make up everything in the universe! In the Beus laboratory, we free electrons from their home in atoms and accelerate them to near the speed of light. In this demo, we show that by accelerating electrons through gas, we can produce colorful plasma inside a glass orb and change the direction of plasma filaments by touching different parts of the glass.
