Lightning with Oudin Coil

(continued)

Many interesting experiments can be performed from an insulated platform. Since the spark jumps to grounded objects, if one stands on a board supported by glass insulators (milk bottles will do temporarily) and touches the discharge ball with a metal rod, sparks may be drawn from one's body by anyone standing on the ground. Care must be taken not to draw sparks from the bare skin, as they might cause a blister. A finger ring, or even a spoon in the mouth, can be used as good contacts from which to draw the spark. A peculiar and weird effect can be had, when one is so charged, by raising the free hand above the head in a darkened room. The person will then be dimly seen outlined by a purple discharge. Small flames will dart from the raised hand, hair, and even from the tips of the ears.
