<p><span style="font-family: Century Gothic,sans-serif;">La sfera di ottone massiccia è sorretta da uno stelo isolante di ebanite. Essa viene caricata e quindi completamente coperta dai due emisferi che lo sperimentatore sostiene tramite i loro manici isolanti. Se si ritirano rapidamente e simultaneamente i due emisferi (operazione piuttosto difficile!) si osserva che questi sono carichi mentre la sfera è neutra, come se la carica si fosse "spostata". Lo stesso risultato si ottiene caricando la sfera già ricoperta dagli emisferi.</span></p>
