Interesting. The (admittedly crude) depictions on their web site seem to
show a device without a plunger. I had assumed that the liquid was
forced out by the pressure in the airspace above the liquid only.
If this is not the case, what are the chances of a 'pen' with only
pressurized air above the liquid actually working?
