Patent Images
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.

Abstract
A liquid-activated lighted ice cube includes a battery-powered electrical circuit and LED housed in a hollow body that resembles an ice cube. The circuit includes electrodes exposed to the exterior of the hollow body that, when in contact with water or other liquid beverage, cause the circuit to turn on the LED and illuminate the beverage.
