• Elastic band
• Piece of gauze or fabric

2. Place the gauze over the neck of the bottom section.
3. Secure the gauze with the elastic band.
4. Position the top section upside down inside the base, forming a funnel.
5. Fill the inverted top 2/3 full with coarse salt.

Why does it work?

Coarse salt is highly hygroscopic, drawing moisture from the air into itself. The water accumulates and drips through the gauze to the bottle's base.

This setup effectively dries the room's atmosphere. Remember to empty the collected water regularly.
