Two wires works as well...
and the ability to do it appears to be genetic.
Genetic? Truly? Wow. No one in my family ever even mentioned it.
I guess they didn’t know that they could. I just tried it one day, and I felt the little twitch. I was amazed.
I can do it with a thin forked branch, but I have never tried it with wires.
Thank you, sir, for that information.
