Why Does Water Have an Expiration Date?

#waterexpiration #doeswaterexpire #bottledwater Why Does Water Have an Expiration Date? Go grab a bottle of water and look at the label — there it is, an expiration date. But water is one of the oldest substances on Earth. It literally cannot rot. So how can plain water "expire" in a few months? The truth is, that date has almost nothing to do with the water itself. It's about the bottle, the law, and a little chemistry you can actually taste. Sealed plain water is safe essentially forever — the date is really a quality estimate for the plastic packaging, plus a surprising legal formality most people have never heard of. Stick around to the end, because we reveal the real reason that date exists, the exceptions that genuinely matter, and why you should never pour out a sealed bottle just because the date passed. 🔔 Subscribe and turn on notifications for more hidden truths behind everyday things!
