Описание: This shows how a clear acrylic sphere containing water and coloured mica particles can be used to trace out rotating currents within the liquid. Rotation is achieved by a small impelor consisting of a ball magnet with two small cube magnets attached to its sides. The ball magnet couples with a rotating magnetic field produced by a fast spinning bar magnet mounted on a motor 20cms below the base of the sphere and hidden from view.
