Situation Puzzle
-
Sonia is going on an extended trip for three weeks. She lives in a remote area where there are frequent electrical power outages which can last up to three or four days. Sonia has quite a bit of food in her freezer which would go bad if it thawed and then re-froze. She does have digital clock and a VCR which would flash 12:00 if the power went out.
Unfortunately the clock and VCR flash even if the power only goes out for a few seconds.
What can Sonia do so that when she returns home she will be able to determine whether the power was out long enough to thaw her food?
Asking a neighbour whether the power was out, isn’t a reliable option because the nearest house is half a mile away, and one house may have power, while another house may have no power. She won’t be able to have a neighbour check on her house every day, and has no one to house sit.
