Why Does Water Go Stale Overnight?

The video explores why water left out overnight tastes stale. It explains that water absorbs carbon dioxide from the air, forming carbonic acid, which lowers the pH and affects taste. Chlorine added for purification can also dissipate, altering flavor. Temperature plays a role, as warmer water enhances taste detection. Despite these changes, stale water is safe to drink. The video concludes with thanks to patrons and encourages viewer engagement.
