Pressurizing lightweight beverage containers, especially for bottled waters, is environmentally responsible and cost-effective. Increasing internal pressure makes a bottle more rigid when filled and capped. This is done by dropping a tiny drop of liquid nitrogen into each bottle then filling the water (or other beverage) on top of the liquid nitrogen. As the nitrogen vaporizes it expands approximately 700 times to create a positive pressure inside the bottle.
