High altitude chemistry?




Since the weather report said sunshine :) we went to the slopes facing south to get us a soft day. This side is not that steep but still have some nice runs and possibilities to make your own tracks inbetween the pists. (but how the heck do you ski windpacked snow with an icy crust?) In the early afternoon we were warm n needed a break n went to this small reataurant at a bueatifful spot around 2500 m altitude. Gabbes chocolate behaved quite normal but the beer was funnier, when pored it looked normal but as soon as we took it out the head grew higher. A minute later the froth was frozen and stayed frozen until the glass was emtied. I know that the japanese often try to get this effect by keeping the glasses frozen but this was different! CO2 and altitude? It was not that cold in the sun.
