Leaving an upturned glass and a piece of paper in the sink before going on vacation is often shared as a simple “home check” trick, but it is not a guaranteed safety method. The idea behind it is mainly to help you notice certain problems when you return.
Why people do this:
- To detect unexpected water leaks
- Place a glass upside down on a dry piece of paper in the sink.
- If a faucet drips, a pipe leaks, or water enters the sink while you are away, the paper may become wet or the glass may shift, giving you a clue that something happened.
- To check whether someone used the sink
- If you leave the setup carefully arranged, changes to the position of the glass or paper may suggest that the sink was disturbed.
- To create a quick “before you leave” reminder
- Small visual checks can help you remember to look for issues like dripping taps or standing water before leaving.
More reliable vacation preparation tips:
- Turn off the main water supply if you will be away for an extended period (if practical).
- Check for dripping faucets and leaks under sinks.
- Unplug unnecessary electronics.
- Empty food waste and take out trash.
- Ask a trusted person to check your home if you will be away for a long time.
- Keep valuables secure and avoid announcing travel plans publicly.
The glass-and-paper trick is a simple indicator, but it should be treated as an extra precaution—not a substitute for proper home preparation.
