Title:
    PIEZOELECTRIC DEMONSTRATOR
Description:
    Demonstrates the piezoelectric effect. The voltage produced by a pressure change on the piezoelectric crystal results in a spark.
Equipment:
    1. Piezoelectric apparatus
Procedure:
    1. Set the spark gap electrodes at about 0.5 cm.
    2. Push the lever firmly up or down and it will produce a spark between the electrodes.
