Yes I think I have one,
Pour a fresh soda with fizz into a tall glass. Fill the glass half way. If
it foams normally, you will have glass filled with a layer of CO2. Tilt
glass up as if to drink but breath in through your nose with liquid resting
against your lips. The need to take a clear breath is quite startling. Would
this be a valid demo?
