The problems you normally think of about living at altitude are things like thinner air and lower oxygen. Before actually coming here, you tend to never worry about things exploding.
Well, things explode.
Buena Vista is 7,965 feet above sea level. Linda and I have long since adjusted to the altitude, but items that are packaged elsewhere don't adjust well. When we first moved to Colorado, we found that tubes of hand lotion and toothpaste we'd brought here from New York would squirt out uncontrollably when opened. Lower air pressure will do that. Since the contents of the tube were sealed at a lower elevation where air pressure is higher, there's more pressure inside the tube. When you open said tube, the pressure is relieved, and whatever's inside squirts out uncontrollably.
I had a new air-pressure related issue this morning when I opened a large container of coffee creamer at work. It was one of those jumbo shopping club deals, and when I unscrewed the plastic lid, the cardboard seal didn't hold out. Bang! Coffee creamer everywhere. They heard it at the other end of the building. Higher pressure inside, apparently.
