Скачать или смотреть Why Bottled Water Has an Expiration Date (The Water Doesn’t Expire)

If water has existed on Earth for billions of years, why does it "expire" once it’s put into a bottle? In today’s video, we’re diving into the science of shelf life to explain the surprising reason your bottled water has a "best by" date—and no, it’s not because the water itself is going bad.
The Mystery of the Expiration Date
H2O is a stable molecule. Under the right conditions, it can last indefinitely. However, the packaging is a different story. We break down the chemical and logistical reasons why beverage companies like Nestlé, Dasani, and Aquafina stamp those dates on every bottle.
In this video, we explore:
✅ The Leaching Process: How PET (Polyethylene Terephthalate) plastic behaves over time. We explain how chemicals like antimony and phthalates can leach into the water, changing the taste and potentially affecting your health.
✅ Microplastics & Heat: Why leaving your water bottle in a hot car accelerates the "expiration" and what happens to the plastic structure under UV light.
✅ Permeability: Did you know plastic is slightly porous? We explain how bottled water can actually "absorb" smells from its environment—like gasoline or household cleaners—if stored too long.
✅ The New Jersey Law: The fascinating history of how a 1987 state law in New Jersey forced the entire bottling industry to adopt expiration dates to simplify supply chains.
✅ FDA Regulations: How the Food and Drug Administration views bottled water safety and what the "indefinite shelf life" ruling actually means for you.
Is It Safe to Drink "Expired" Water?
We give you the verdict on whether that two-year-old bottle in your emergency kit is still safe to drink and the best way to store water for the long term (hint: glass or high-quality steel is king).
