Does the fridge light really go off when the door closes?

The answer

Yes. A fridge has a small switch in the door frame. When the door closes, it pushes the button in, and the button switches the light off. When the door opens, the light comes on again. In this made-up case from Matter of Record Files, Inspector Fig tried peeking, sneaking up on the door, and opening it really, really fast, and the light was always faster. He even left a phone recording inside and shut the door, and the video came out completely black. Then he spotted the little button tucked into the door frame, and Maisie turned out to be right all along.
