    I have seen these bottles leaned up against telephone poles for a long time and wonder what the are there for. They have guages and looks like a tube running up the pole. Not sure if is the right forum to post this but I bet someone will have an answer.
    Thanks

    Phone company keeps cable under pressure to keep water out, usually is nitrogen.

    Nitrogen is used where positive pressure is needed to keep air and water out. It is used in transformer and such. It prevents moisture and rustion. Also keeps potato chips fresh.

    And shredded cheese! Actually, CO2 is a better preservative, but it can give an "off" flavor if too much is used. CO2 will also be absorbed by cheese, causing the bag to vac-pack itself over time. Mainly, gotta get the oxygen in the bag below 3%.
