r the drain.
Place an upside-down glass or cup on top of it.
That’s it. You’ll leave knowing your sink is taken care of—and you’ll have one less thing to worry about on your trip.
Why Not Just Use a Regular Stopper?
It’s a fair question. Traditional sink plugs can loosen, shift, or even change shape with heat over time. They’re not always reliable, especially if you’ll be away for more than a few days.
An upside-down glass, on the other hand, doesn’t depend on a tight seal. It simply creates a quiet, stable barrier that works surprisingly well.

The Science Behind This Clever Trick
This little hack actually makes sense once you understand how your plumbing works.
Every sink has a curved pipe underneath, called a trap, that holds a small amount of water. That water acts as a natural seal, blocking odors and gases from rising through the drain.
