Hi Antonio
Electrostatic demonstrations: electric bells
The unit is supplied by a voltage source with a maximum of 18 kV. The voltage is slowly increased so far until the metal clapper swing between the bell shells and strike it. The clapper of the bell shells are attracted by the bell dome with the opposite charge or repelled by the middle bell shell. After contact of the outer bell clapper the discharge and swing back. The process begins again by reverse charging.
Best wishes
