It's made from a wooden mortar and pestle and some scraps of guitar string. I strapped a rechargable battery to my thumb to use as a slide, just like Baba Yaga used to do.
That's it for instrument-a-day for this year, but Jason, Chris and I will be performing with some of these instruments on Wednesday at Barbes in Brooklyn.
Nice, another possibility in the kitchen is the Mix_o_caster [http://failrate.com/b/images/handmade_music/mix_o_caster_spoon_guitar.png]. I think you could fashion a berimbau from a ladel, also.
