Why does the participant have to stand on a stool?
The stool is made of either plastic, rubber or any other insulating material. A plasma ball acts as a miniature tesla coil in which coils of wires with electrons oscillate at a high frequency. This causes the electrons to release and travel through the air, creating sparks that can be seen. Standing on the stool insulates the participant from the ground, allowing the electrons to gather in the body and cause the hair-flying phenomena to become more obvious.
Why does the hair in the participant float?
This is due to static electricity, caused by an imbalance between negative and positive charges. The plasma which causes electrons to gather in the body creates a mass of negative charge in hair. Objects with the same charge repel each other. This can be seen in hair, with the individual strands repelling each other and ‘floating’ in the air.
Why was the participant shocked by the touch by another?
The touch caused some electrons to conduct through the bodies in the form of static electricity. This caused the two participants to feel a shock at the touch.
Why does a fluorescent light bulb light up near a plasma ball?
A plasma ball is miniature tesla coil. Coil of wires with electrons oscillating at a high frequency, causing them to release and travel through your body to light up the fluorescent light bulb. This is also why there is a spark the hand when the glass is touched.
