Abstract

A floating toy is provided which can achieve varied and entertaining movements by means of a simple composition. The floating toy comprises: a liquid container section (11, 12) containing liquid therein; a figure (2) of lower specific gravity than the liquid, accommodated inside the liquid container section; magnetic bodies (31, 32) accommodated movably inside the liquid container section; line members (41, 42) extended between the figure and the magnetic bodies; and electromagnetic mechanisms (51, 52) that act on the magnetic bodies. The magnetic bodies and the figure are caused to move against the buoyancy force of the figure, by passing current through the electromagnetic mechanisms, and are caused to return to their original positions by the buoyancy force of the figure, by releasing the passage of current through the electromagnetic mechanisms.
