Condition :   Good  
Principle :   Electrostatics   
Area of Study :  Electricity & Magnetism  
Equipment :   Wimshurst generator and bell chimes.
Procedure :   Connect the generator to the bell chimes and separate the spark gap to at least 2".  Slowly turn the Wimshurst generator to build up charge.  If the balls do not start hitting the chimes on their own when the charge is built up, you may have to slightly shake the apparatus.  When operating properly the balls should go back and forth between negative and positive chimes creating a ringing sound.
