I was inspired today by this slightly crazy idea (graduated wine glasses which indicate which note will be played if you run your finger around the rim when the wine is at a certain depth in the glass).
One note at a time seems a bit limited, though, so today’s invention is to incorporate a syringe in the stem.
Someone holding the glass can push or pull the syringe to raise or lower the level of the wine and thus alter the note played on the rim.
