"You can't see electricity or hear it or feel it."
Let me correct you about that one, at least.
You can feel electricity, - as most electricians can attest to (very few of us have not inadvertently touched something that was live at 240 volts to earth, and you can feel that, all right. Talk about livening up your day!)
That is why such devices as cattle prods and electric fences work like they do; the animal on the receiving end can feel the passage of electricity through its body - and feel it very well!
Bill.
