Ama's and High Elevation

If you've ever purchased a bag of potato chips in Sac, then driven to Tahoe, you've seen how much the bag puffs up.

lol, first time I took the kids up to tahoe for a ski trip we had a couple bags explode in the back of the suburban that scared the hell out of everyone.  I thought snow fell off a tree and clobbered us or something. 

Since we're on this subject....on another trip to the cabin we picked up a couple heineken baby kegs in sac and when we got to the cabin they poured 99% foam....bottles were fine, however.....wth was that about?

PV = nRT

Thx boyles and charles lol
