EVP by Alan Rorrison - Trick

This thing ought to come with a warning label: "Not for the faint of heart." Wow! A home run at your next Halloween party for sure. Fortunately, I still had an old iPhone 10 still laying around which allowed me to plug in the audio/control jack. I'll use that old phone exclusively for this effect. My newer iPhone does not have this input socket, so I found no way to control the effect. All that being said, the reactions obtained from this trick are more than worth trying to find a way to make it work.
