When you’re packing your bags and setting your out-of-office reply, the last thing on your mind might be the kitchen sink. But what if we told you that leaving a simple upturned glass and a piece of paper in your sink could help protect your home while you’re away?
It sounds strange — maybe even superstitious — but this surprisingly effective trick is backed by practical science, and it’s been quietly used by clever travelers and seasoned homeowners for years.
🥛 The Simple Setup: What You Do
Before you leave for vacation:
-
Take a clear drinking glass, fill it with water, and place it in your freezer.
