In my family, it comes down from my dad’s side.
He showed me how to do it with the wires, and it worked!
Now, I’ve polled my family, and my siblings and their/my kids can all do it (so far), but none of their spouses.
That’s fascinating, Sir.
I never had children, and my family, but for one sister, has passed away.
I’ll never know where I got it or whether I could have given it to my kids.
