Before heading out for a trip, some New Yorkers swear by a clever trick: placing a coin in their freezer. This quirky hack, popularized in urban circles, isn’t just a superstition—it’s a practical way to check if your freezer stayed cold while you were gone, potentially saving your food and protecting your health from spoiled goods. Here’s why this simple coin trick is catching on and how you can use it to avoid food safety risks.
What’s the Coin-in-the-Freezer Hack?
The coin-in-the-freezer trick is a simple way to detect power outages or freezer malfunctions during your absence. Here’s how it works: fill a small cup or container with water, freeze it, and place a coin on top of the ice. Put the container back in the freezer before you leave. When you return, check the coin’s position. If it’s still on top, your freezer stayed cold. If the coin has sunk to the bottom or is embedded in the ice, it means the freezer thawed and refroze, signaling that your food may have spoiled. This hack helps you avoid eating unsafe food that could lead to foodborne illness.
Why New Yorkers Love This Trick
New Yorkers, known for their fast-paced lives and frequent travels, rely on this hack for its simplicity and effectiveness. Power outages are a reality in bustling cities, whether from storms, grid issues, or apartment maintenance. A freezer thaw can go unnoticed, as food often refreezes and looks fine but may harbor bacteria like salmonella. This trick, which takes minutes to set up, offers peace of mind by revealing whether your freezer stayed at a safe temperature. Its genius lies in using everyday items—a coin and water—to solve a practical problem without expensive gadgets.
The Science Behind the Hack
The trick works because of how ice behaves during a power outage. If the freezer loses power for a prolonged period, the ice in the container melts, causing the coin to sink. When power returns, the water refreezes, trapping the coin below the surface. This is a clear sign that temperatures rose above 0°F (-18°C), the safe threshold for frozen food. Research indicates that food thawed for over a few hours can develop harmful bacteria, making this hack a lifesaver for avoiding food poisoning, especially for high-risk items like meat or dairy.
Benefits of the Coin Trick
This hack offers practical advantages:
- Prevents Food Poisoning: Identifies spoiled food that looks safe but may be contaminated.
- Saves Money: Avoids wasting food by confirming if it’s still good or needs to be tossed.
- Simple and Cheap: Uses just a coin and water, no need for costly freezer monitors.
- Peace of Mind: Ensures confidence in your food’s safety after a trip.
These benefits make the coin trick a must-try for anyone leaving home for days or weeks.
How to Do the Coin-in-the-Freezer Hack
Ready to try this New York-approved trick? Follow these steps:
- Prepare the Container: Fill a small cup or container with water and place it in the freezer until fully frozen.
- Add the Coin: Place a single coin (any denomination) on top of the frozen ice.
- Check on Return: When you get back, inspect the coin. If it’s on top, your food is likely safe. If it’s at the bottom or frozen inside the ice, discard perishable items like meat, fish, or dairy.
- Use a Visible Coin: Choose a coin that stands out, like a quarter, for easy spotting.
For best results, place the container in a stable spot in the freezer where it won’t tip over.
Tips for Success
To make the hack foolproof:
- Use a Small Container: A shallow cup or bowl ensures the coin moves noticeably if the ice melts.
- Check Immediately: Inspect the coin as soon as you return to catch any issues before using food.
- Combine with Other Precautions: Store critical items like meat in the coldest part of the freezer to minimize spoilage risk.
If you’re leaving for an extended period, consider emptying perishable items or unplugging the fridge entirely to save energy and avoid risks.
