Re: Tarnished Silver as a Crystal Radio Detector
I believe a lump of coke is suggested in the 'Experimental POW radio' page in the Ladybird book 'Making a Transistor Radio'. That is the one page of the book I never tried as a kid.
I was talking to a teenage-ish audience about crystal detectors and mentioned that a 'lump of coke' can work. Seeing puzzled looks around the room I added 'The fuel. Not the soft drink.... or the drug'
