Comments:
Remove pointed metal items such as keys and microphones. Stand on the
insulated stool. With the variable control fully counterclockwise, turn
the power on. Hold the pointed probe against the sphere while turning
up the motor. Place your other hand on the sphere BEFORE removing the
probe. DO NOT REMOVE YOUR HAND and stay away from anything metal. Allow
yourself to charge up. Fine, clean, dry hair stands on end best. Try pointing
at a student or the electrified strings.
