Leaving an upturned glass and a piece of paper in the sink before a vacation is a popular household tip shared online, but it is not a proven or essential travel safety measure. The idea is usually presented as a way to detect problems while you are away, but its usefulness is limited.
Here are some common reasons people suggest this trick:
1. Detecting unexpected water leaks
The idea is that if a glass is knocked over or water appears in the sink, it may indicate a leak or plumbing issue. However, a glass in a sink is unlikely to reliably show whether a serious leak occurred elsewhere in the home.
Better steps before leaving:
- Turn off the main water supply if appropriate for your home.
- Check faucets, pipes, and appliances for leaks.
- Consider a leak sensor if you have concerns.
2. Checking whether someone entered your home
Some versions claim the paper or glass can act as a simple “tamper indicator.” In reality, it is not a reliable security method.
Better options:
- Use timers for lights.
- Ask a trusted person to check on your home.
- Use appropriate home security devices.
3. Preventing sink odors
A more practical vacation tip is to prevent unpleasant smells:
- Clean food debris from drains.
- Pour water into rarely used drains to keep traps from drying out.
- Close toilet lids and cover drains if needed.
Useful things to do before a trip
✅ Empty trash and remove food that may spoil
✅ Unplug unnecessary electronics
✅ Set your thermostat appropriately
✅ Lock doors and windows
✅ Arrange mail/package collection
✅ Check smoke and carbon monoxide detectors
The glass-and-paper trick is harmless, but it should not replace real preparation measures that protect your home while you are away.
