Hopkins FloTool 10101 AntiFreeze/Windshield Washer Spout

It used to be that you could find these spouts "everywhere", but I have not
been able to find them at all locally in recent times. They are great for
pouring stuff out of gallon bottles into smaller containers, but there used
to be a pink version with a smaller outlet that was even more useful. Still,
my only problem with them is that they are a bit stiff to turn, and opening
the spout is likely to start to remove the spout from the bottle instead,
but maybe that will go away with use. The stiffness is the only reason not
to get a 5 star rating.
