Why You Should Always Put a Coin in Your Freezer Before a Vacation

Here's where the trick comes in. Before you leave, take a small plastic bowl or cup and fill it with water. Place it in the freezer and let it freeze solid. Once the water is completely frozen, put a coin on top of the ice—and leave it there. That's it. When you return from your trip, check the coin. If it's still sitting on top of the ice, nothing changed—your freezer stayed cold the entire time.
