Playing Music with Food

I have raved and given the highest praise to that wonderful, poisonous and yet delicious buah keluak seed but is it possible that there is still something more to this versatile food that I forgot to mention? Yes, indeed. It can be recycled and made into a musical instrument like this rattle which was spotted at the market in Ubud, the cultural and crafts center of Bali. No waste here.

I wonder what other food stuffs could be made into musical instruments. This might be made into an interesting themed menu for a restaurant where ingredients or leftovers from the main courses be later used by the resident band to make sweet melodies for the night's entertainment. It would be great. For me, it would give me a lovely excuse to play with my food.
