The vibrations triggered the hook to create small indentations within a bit of tin-foil that he had stretched round a revolving cylinder. The needle was arranged in order to track the spin out of control round the cylinder in addition to becoming vibrated backward and forward from the container foil area. Once the procedure had been reversed and also the needle had been permitted to proceed together within the round groove, the indentations vibrated the needle and also the membrane layer, as well as seem had been created with the horn.
