Circuit Bending Exercise
Bring Circuits: something electronic that makes noise. Electronic toys, like toy guitars or keyboards, speak 'n' spells, voice changers toys, things that have voice chips, laser blast sounds, animals, etc. Just one rule: BATTERY POWER ONLY! Circuit bending involves a highly scientific process of randomly poking wires into open, powered-up electronics, so NOTHING that plugs into the wall, that uses large batteries, or has large capacitors, like a TV.
