A container is provided therein with a hollow tubular body which is provided at the bottom end thereof with an end piece having a first magnet. An ornament is movably disposed in the hollow tubular body and is provided in the underside of the bottom thereof with a second magnet for bringing about a repulsion effect in conjunction with the first magnet. The ornament is caused by the repulsion effect to trip up and down in a reciprocating manner in the hollow tubular body at such time when the container is moved up and down. The ornament is also caused by the repulsion effect and the inertia effect of the ornament to suspend in the hollow tubular body.
