ALLISON: Nick did an experiment at school today.
ME: Oh, yeah? What did you do, buddy?
NICK: We had to look and figure out what floats.
ALLISON: They had a tub of water and they put things in it to see what would float and what would sink.
ME: I see. And what sank?
NICK: A teapot.
ME: Why did it sink?
NICK: It filled with water and got heavy.
ME: Ah. And what floated?
NICK: A small pony.
ME: Okay. And why did it float?
NICK: It was dead.
