AN ELECTRIC BREEZE.
If a sewing needle is connected to one of the discharge rods of a static machine and the point of the needle is presented to the flame of the candle while the machine is in operation, the flame will be repelled just as if a breeze or current of air were issuing from the needle. This is caused by the "brush" discharge which takes place whenever high voltage electricity has a chance to escape from a sharp point or edge. The brush discharge will be much more marked if the condensers or Leyden Jars are not connected to the discharge rods. The "electric breeze" can be felt if the point of the needle is brought near to the side of the face. It is necessary that the needle and the wire connecting it to the static machine be very carefully insulated from all surrounding objects which might dissipate the electricity before it has an opportunity to escape from the needle point.
