    Off topic, but I recall my avid skiing days.  We would try to save a few
    bucks when driving from Denver to the condo half way up the slope in
    Breckenridge, CO (approx. 12,000 ft) by purchasing potato chips, Twinkies
    and other "carbo loading" necessities in Denver.  When we pulled them out of
    the bag at the condo, the packaging had expanded like a baloonfish.  No
    wonder, they had been "inflated" by a 2 1/4 psi drop in air pressure.
