Motion liquid display toy

A motion liquid display toy comprising a base;

• a transparent container mounted on said base and holding a liquid;
• a floating ornament floating in said liquid and having a magnet at a bottom side;
• and
• a transmission mechanism mounted in said base and controlled to force said floating ornament to move in said liquid,
• wherein said transmission mechanism comprises a dial horizontally disposed in said base below said transparent container and having a center hole;
• an output shaft extending vertically from the center hole of said dial;
• a link suspended above said dial and extending in a horizontal plane parallel to a principal plane of said dial, said link having a first end coupled to said output shaft so as to be rotatable in said horizontal plane about a vertical axis of said output shaft, and a second end connected to a coupling device;
• and
• a magnetic member having at least two magnetic poles of opposite polarity coupled to the coupling device of said link, said magnetic member establishing a magnetic coupling with the magnet at the bottom of said ornament,
• wherein said coupling device is arranged to permit said magnetic member to move with respect to said link as said link rotates about said shaft, said movement of the magnetic member with respect to said link being different from said rotation of said link about said shaft such that said magnetic member carries out a compound motion made up of a first motion in the direction in which the link rotates about the shaft and a second motion which is different from the first motion, thereby causing a relative position between said ornament and respective said magnetic poles to change as the link rotates, in turn causing a polarity and strength of the magnetic coupling to vary and thereby cause said floating ornament to move forwards and backwards in said liquid, to sink or float in said liquid, and to turn round.
