Overheard

While walking by the bathroom this morning, this is what I overheard:

Jayce: "How come the water level in the tub gets higher when someone gets in it?"

Jaina: "That's because of my body pressure. Or water pressure."

Jayce: "Because of how much the water weighs? What does water weigh, anyway?"

Jaina: "Two or three gallons? I think."

Don't worry. We had a little science lesson on displacement this morning :)
