Where's Alistair when he's needed? Cuz that's a can of worms for sure.
I have a problem envisioning a significant (if any) amount of alcohol
evaporating through those two tiny nozzles, unless you were to leave
the liquid in there for a year or more. At that point it could have
escaped through the porous plastic reservoir, but say it somehow was
proven to be true, wouldn't the installation of a simple w/washer
check valve resolve this issue? (insert happy face here so I don't get
in trouble)
