1. A liquid-activated lighted artificial ice cube, comprising:
- a hollow body;
a pair of electrodes exposed on the exterior of said hollow body;
an electronic circuit disposed within said hollow body, said circuit including a battery, an LED, an active circuit element controlling current between said battery and said LED, an electronic switch responsive to current flowing through a conductive liquid path between said electrodes for controlling current between said battery and said active circuit element, said electronic switch being connected to said pair of electrodes;
wherein said electronic switch disconnects said active circuit element from said battery in the absence of a conductive liquid path between said electrodes and thereby deenergizes the entire circuit.
