Self-Refilling Wine Glass

The Self-Refilling Wine Glass is designed for connoisseurs who refuse to abandon their favorite beverage mid-conversation. Using advanced nanotechnology, this glass adapts to the drinker's preferences by filling itself with precisely one-third of a standard serving every time it reaches a predetermined level. Should the imbiber suddenly recall a forgotten fondness for another varietal, merely whisper the grape variety into existence – and voilà! Should the self-filling process fail due to, say, excessive clinking or distracted sampling, simply rattle the stem three times to reboot the system.
