“How can bird’s feet stay on electrical wires and not be electrocuted?”
This was the question from my curious 7 year old daughter as we drove along.
Answer offered by me, the adult:
“Because their feet don’t conduct electricity. Electricity doesn’t pass through their feet because of what their feet are made of.”
Question from the older 15 old daughter:
” What are their feet made of?”
Well, I didn’t know.
It turns out that even my first answer was wrong.
Here is the simplest explanation I could find, from Rocky Mountain Power:
The bird is not grounded. It has not created a path of lesser resistance for electricity to follow. If the bird simultaneously touched two wires, the difference in resistance between the two wires would create a path through the bird and it would be electrocuted.
Well there you go! Apparently it works ok for small birds, but overhead electrical wires can be quite a danger for larger birds.
The important thing is not to stop questioning.
Kid’s don’t ask silly questions.
It’s not a silly question if you can’t answer it.
