One thought on “Microphone-Coherer: Extraordinary

  1. Part of the problem is our tendency to isolate things, objects, when in reality everything is connected, presumably, at the quantum level.

    The simple experiment of plastic tube, metal filings, fan and battery with pizeo-lighter – the spark seems to complete the circuit between the two electrodes or screws so that the metal filings adhere to each other and to the eletrodes thus completing the circuit. He has to physically knock the metal fillings so they fall and disconnect the circuit.

    So how does a transient spark cause the filings to cohere and connect to the electrodes?

    My brain has turned to pudding.
