On the way to school:
Dominic: Is the earth moving fast?
Daddy: Yes...(mental calculation...25,000 miles at the equator in 24 hours)...very fast. We are moving faster than most planes fly.
Dominic: Why don't we fall off?
Daddy: Because we stick to the earth. If you look at the earth from space, people in Australia are standing upside down.
Dominic: (makes a fist and points East) and people here stand like this (horizontal).
Daddy: And people in the North stand upright.
Dominic: People in the North just turn around and around on their feet when the earth spins?
Daddy: I guess. That's how it works. And if you jump, the earth under you will move and you land on a different part of the earth
Dominic: If we jump here, when we land we can be already in school.
Daddy: Or you may smash into a moving building.
Dominic: Or smash into the tram.
Daddy: Don't forget, the earth moves around the sun.
Dominic: So when we jump, when we land, the earth is no longer under us so we fall in outer space.
Daddy: Right. The earth has already moved around the sun.
Dominic: Wow.
