The Resistor JelTone is an edible toy piano created by NYC Resistor members Ranjit Bhatnagar, Astrida Valigorsky, Mimi Hui and myself for the Jello Mold Competition.
As part of our experiments we realized that jello and fruit, which contain a lot of water, are conductive. Embedded in each jello/fruit key is a sterling silver pin (food safe) connected to an Arduino microcontroller underneath the piano’s base. Below the piano’s case is another sterling silver pin. With this setup, the JelTone can either be played with a metal utensil connected to the Arduino, gloves enhanced with conductive thread, or bare hands by touching both a key and the piano’s case.
If you’d like to make your own, you can get the project files, code and instructions from Thingiverse.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

Very cool! I kept getting the germophobe chills watching the player touch every bit of fruit. I’m guessing that this would be mostly a decorative, playable garnish.
Right, the fruit version was not meant to be eaten 🙂 But at the Jell-O Mold Competition we let people both play and eat the piano. To make it clean and safe they would play it with a clean spoon and a (jello) piece of the piano was handed to them with food-safe gloves: http://www.flickr.com/photos/ranjit/5910418380/
