Unknown to me if that's real, but you can hear AM radio with a sausage of you're next to the transmitter's antenna: https://youtu.be/GgDxXDV4_hc https://youtu.b

  this is a fantastic demo! just to nitpick, though, it's really the plasma between the sausage and the antenna that's making the sound; the plasma heats up regardless of which direction the current was flowing, so you don't need a 'detector' converting ac to dc as you do in a conventional radio. for fillings the most likely explanation is a parasitic schottky rectifier accidentally formed from a metal oxide, rather than such a resistive phenomenon (though it's not impossible)
