<p>A device which simulates natural flowering actions, including growth and efflorescence, is actuated by partial immersion of a stem into a liquid. An aperture through the stem base admits the liquid into the stem. A piston slidably disposed within the stem is driven downwardly by the bias force of a resilient spring while an agent which impedes the piston motion dissolves in the liquid. Growth is simulated by a sleeve outside the stem which descends in relation thereto to push the flower upwardly. A simulated corolla is attached to the stem and gradually rotates and opens during the ascent thereof. A cam controls the pivotal position of lifters which open and close the corolla. The petals of the corolla vibrate before opening and open with variations in starting time. As the corolla opens, a surprise gift, gradually ascending on a presentation platform, is revealed. The device may be reused.</p> |
