LED liquid-sensor ice cubes — safe, colorful drink decoration with automatic on/off and simple care Key benefits Automatic activation: Built-in liquid sensor turns the LEDs on when immersed in water and off when removed, so lights only run while in your drink or display. Eye-catching color effects: Each cube cycles slowly through seven colors, changing every 2–3 seconds for smooth, attractive lighting. Safe for cold drinks: Made from food-safe acrylic plastic with no chemical change or toxicity — suitable for use in all kinds of cold or room-temperature beverages (do not use in hot drinks). Simple maintenance and reuse: Three integrated button cells power the LEDs. After use, dry the sensitive area (screws and battery) to reuse; note overall runtime limits described below. Features and performance Power: Three integrated button cells; LEDs activate automatically in liquid. Color cycle: Seven colors, approximately 2–3 seconds per color. Runtime: About 20 hours total. Brightest output for roughly the first 8 hours; brightness gradually decreases after that. Intended as a temporary/disposable decorative item as light output diminishes over time. Material: Food-safe acrylic plastic — non-toxic and safe for beverage contact (not suitable for hot liquids). Care and compatibility Compatible with all cold and room-temperature drinks; do not place in hot beverages. After removing from liquid, thoroughly dry the sensitive area (screws and battery) before storing or reusing. Easy to clean — wipe the surface and dry before storage. Use scenarios Cocktail parties and bars: Add a colorful, automatic glow to individual glasses or beverage displays for instant atmosphere. Weddings and events: Place cubes in centerpieces, punch bowls, or glass vases to create subtle, changing color effects. Romantic dinners and small gatherings: Drop a cube into a partner’s drink to add a simple, low-effort visual accent. What to expect Turn-on when submerged and turn-off when removed. Smooth seven-color cycle with about 20 hours total illumination; brightest during the first 8 hours and gradually dimming thereafter. Safe contact with drinks thanks to food-safe acrylic; avoid heat and dry the battery area after each use to maintain functionality.
