Another Moment in the Trenches

Another moment with 9th grade science: I'm explaining about metals, that they can be rolled into thin sheets and pulled into wires, and they are good conductors of heat and electricity. I said "Now you've probably heard about people who break into air conditioning units to steal copper wire. Why do you think that there is copper wire in air conditioning units?"

"To get money!"
