Re^2: OT: Physical exitation of pressurised liquid gas.

The poptop only works if the pressure inside the jar is less than the atmospheric pressure. To liquify a gas will by definition need more than atmospheric pressure (unless you cool it way down, but that is cheating).

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
