ABSTRACT:
A changeable-appearance device includes an inner container open at the top and closed at the bottom by a bottom wall, and an outer light-transmissive container open at the top and receiving the inner container with an annular space between the two containers. The outer container includes a base closing its bottom and defining a compartment with the bottom wall of the inner container. The compartment includes one or more ampules containing a changeable-appearance substance effective, when an ampules is ruptured, to release its respective substance into the annular space between the two containers. One of the containers includes an ampule-engaging element effective, upon rotation of one container with respect to the other, to engage and rupture the ampule, and thereby to release the substance in the annular space between the two containers. In the described preferred embodiment, the changeable-appearance substance released from the ampule is a chemiluminscent substance producing a chemiluminscent glow, but may be an effervescent substance to produce an ornamental effervescent appearance, or a color-changing substance to produce an indication of a previous opening of the device.
