This is a video where one of many people attending the ITP show, sat down and played a drink from the Pianocktail.
Summary on how the Pianocktail works:
1. you seat on the stool so the piano knows you are ready to play your drink.
2. Play a tune you would like to taste.
3. Stand up to let the Pianocktail know you are done playing and would like your drink.
4. Taste your song.
