shake a can of beer... sprouts a fizz
and foam...
shake a glass bottle of beer...
nothing...
i know aluminium cans are thin
and that glass bottles are thicker...
but glass acts like an insulator
of carbon dioxide pressurised in water
while metal of any kind seems
to conduct it; or something like that,
i'm not going to stress any orthodoxy
that will have to be stressed by
future generations in all its changeless
accuracy.
