WebAug 15, 2024 · Light the match and toss it into the bottle. Set the peeled egg on the bottle’s mouth, with the small end of the egg down. The egg will then pop into the bottle. When the air in the bottle is consumed by the flame of the lit match, it causes the air pressure in the bottle to become lower than that outside of the bottle. WebWhy does boiling water freeze in cold air? How It Works. Boiling water is at the point of changing from a liquid into water vapor. It has the same vapor pressure as the air around it, so it has plenty of surface area to expose to a freezing temperature. The large surface area means it's much easier to freeze the water than if it were a liquid ...
