Curious Effects Of Oil Upon Water And Water Upon Oil
Fasten a piece of pack-thread round a tumbler, with strings of the
same from each side, meeting above it in a knot at about a foot
distance from the top of the tumbler. Then putting in as much water as
will fill about one-third part of the tumbler, lift it up by the knot,
and swing it to and fro in the air; the water will keep its place as
steadily in the glass as if it were ice. But pour gently in upon the
water about as much oil, and then again swing it in the air as before,
the tranquillity before possessed by the water will be transferred to
the surface of the oil, and the water under it will be violently
agitated.
