Introduction:
Going on vacation is exciting, but leaving your home unattended comes with its own set of concerns—especially when it comes to leaks, plumbing issues, or power outages. There’s a clever, low-tech trick making the rounds among savvy homeowners: placing an upturned glass and a piece of paper in your sink before heading out. This simple method acts like a passive alarm system that can help alert you to potential plumbing or freezer problems when you return. Here’s how to do it, why it works, and how you can tweak it for even better peace of mind.
Ingredients:
1 clean drinking glass (preferably transparent)
1 small piece of paper (plain or a sticky note)
Water (enough to fill a small bowl or cup)
Optional: a freezer-safe bowl or cup
Instructions:
Sink Method (Detecting Leaks):
Clean your sink thoroughly before leaving.
Place a dry piece of paper in the center of the sink.
Turn a glass upside down and place it over the paper, creating a small air pocket.
Leave it undisturbed while you’re away.
Why it works:
If any water leaks or drips occur while you’re gone (from a leaky faucet, a sudden pipe issue, or backup from clogged drains), the paper will get wet or the glass will shift. When you return, checking if the paper is still dry is a quick way to assess if any leaks happened.
Freezer Variation (Detecting Power Outages):
Fill a small bowl with water and freeze it completely.
Place a coin or piece of paper on top of the frozen surface.
Leave it in your freezer before you leave.
Why it works:
If a power outage occurs, the ice will melt. If the coin is found at the bottom of the bowl when you return, it indicates a full melt and refreeze — meaning your food may have thawed and could be unsafe.
Serving and Storage Tips:
Don’t drink from the glass when you return — it’s been sitting in an unsanitary area.
Dispose of the paper whether it’s wet or dry to avoid bacteria buildup.
Reset the trick anytime you leave for more than a day or two.
