Michael has a spherical ball of dirt that he has been carrying around with him for a couple of months. This is his "meteorite". It was on the breakfast table this morning, next to a glass of water.
Michael: If I dropped the meteorite in here would it explode?
Dad: No. But it would turn to mud and make a big mess.
Michael: And I'd be in big trouble?
Michael: Bigger than the Earth?
Michael: Bigger than the Sun?
Dad: ... I guess.
Michael: Bigger than Antares?
Dad: ... WHAT?
Michael: Antares. It's the fifteenth brightest star.
