The Magic Bottle
Take a small bottle, the neck of which is not more than the sixth of
an inch in diameter. With a funnel, fill the bottle quite full of red
wine, and place it in a glass vessel, similar to a show-glass, whose
height exceeds that of the bottle about two inches; fill this vessel
with water. The wine will shortly come out of the bottle, and rise in
the form of a small column to the surface of the water; while at the
same time, the water, entering the bottle, will supply the place of
the wine. The reason of this is, that as water is specifically heavier
than wine, it must hold the lower place, while the other rises to the
top.
An effect equally pleasing will be produced, if the bottle be filled
with water, and the vessel with wine.
