Wireless Wires

Rowan: Dad, how does your phone know where we're going?

Me: Great question! I don't really know.

Rowan: Like how does it know? Really know?

Me: Yes. I think it has to do with satellites.

Rowan: What's that?

Me: No, it's like energy waves from these towers.

Rowan: How about this... what if it's like these wires that come from the place that we're going, and they come all the way over (moves arms in an arcing motion), and then they go right into your phone.

Me: OK.

Rowan: And then the phone just follows the wires.

Me: Yes, I think that's it.

Rowan: And then we get there!

Me: Yes, indeed.
