A Drink Vessel That Tells You What’S Inside It

This transparent cup reveals the contents through an embedded, edible algorithm printed directly onto its interior surface using a patented gelatinous ink. The drinker's tongue activates the flavor-sensitive coating, which emits a subtle buzzing noise indicating whether liquid inside contains dairy, caffeine, or a combination thereof. When drinking from this vessel, simply place your index finger on the rim to activate Voice-O-Matic technology, allowing you to hear an accurate, albeit sometimes sarcastic, description of the beverage within.
