Catarina Mota, Alicia Gibb and Shelby Arnold built a speaker made entirely from copper foil tape on cardstock. They’re testing it with the JelTone edible piano. The speaker’s design comes from the High-Low Tech Research Group at MIT.

The tape is applied to the paper in a coil-shaped pattern. When connected to the output lines of the JelTone with alligator clips, the speaker produces a soft hum. This sound matches the tones that the piano produces when hooked up to a real amplifier, though it’s a lot softer and noisier.
