of "wind" that goes along with the effect.
This wind pushes the wheel in the opposite direction from the points.
The wheel spins fast enough for the discharge to appear as a continuous
Best way to make this is to use a thumbtack pushed through a piece of

Cut a bar or a cross shaped piece of metal making points at the end of
Find out where the balance point for this is and make a small dimple

Fit the dimple into the raised point of the thumbtack and turn on the
