What Would You Do?
So there you are … in a room with three light switches. In the next room, there are three bulbs, each one connected to one of the switches and all are off. You can’t see into the room with the bulbs. So how do you figure out which switch operates which bulb? I post the answer later …. 
And, no, you don’t put my dad in the next room so he can say, “Who left a light on? Turn it off! I’m not made of money, you know!”
