70 / 100
Mostly True

Water may taste strange if left out overnight due to absorbing gases from the air. It's advised not to leave a glass of water open to the air.

Infact verdict: Mostly True (70/100).

The claim that water may taste strange when left out overnight because it absorbs gases from the air is supported by multiple sources. These sources explain that water absorbs carbon dioxide, forming carbonic acid, which alters its taste. This is a well-documented scientific phenomenon. The second claim, advising not to leave a glass of water open, is an opinion and cannot be factually verified.
