“The little Plateau experiment,” worked out
by the physicist J.A.E Plateau, 1801 – 1883. Compare the
description by Vincent Knauer in his lectures, “The Main
Problem of Philosophy,” Vienna and Leipzig 1892: “One of
the nicest experiments is the Plateau experiment. A mixture of water
and alcohol is prepared, having the exact weight of pure olive oil.
Into this is poured a rather large drop of oil. This does not float
on top of the liquid but sinks to the middle of it, in the form of a
ball. A small disc of cardboard is then perforated in the center by
a long needle and lowered carefully into the middle of the ball of
oil, so that the edge of the cardboard becomes the ‘equator’
of the ball. The disc is now set into motion, at first slowly, then
faster and faster. Naturally the movement is imparted to the ball of
oil, and as a result of the strength of the movement, parts of the
oil drop away and continue the movement separately for some time,
first in circles, then revolving as tiny balls. In this way there
arises something surprisingly similar to our planetary system: in
the center the largest globe, like our sun, and moving around it
smaller balls and rings, like our planets with their moons.”
