Here's the trick:
Fill a cup with water and freeze it.
Once frozen, place a coin on top.
Check the coin's position when you return:
If it's on top, your power was stable, and your food is good.
If it's at the bottom, the power was off long enough for the ice to melt, indicating possible food spoilage.
