Musical Wine Glasses

For those who are tone-deaf but love to entertain dinner guests, there are Musical Wine Glass. The musical wine glasses are etched with musical-note markings that correspond to the level of the liquid you need to fill the glass with, in order to get the right note. When users run their fingers along the rim of a filled glass, a sonorous note is created. The glasses, which are made of crystal, cover a 12-note octave, from A-flat to G—to help you channel your inner Miss Congeniality.(via)
