Play Music with Anything
Queaky works on a closed circuit: when it senses a complete loop it makes a sound, and the tone changes with the resistance in the circuit. Play with leaves, a drop of water on string, or even just your fingers.
Test Materials
Use different materials in the circuit and hear how resistance changes the tone — real circuit science through sound.
Prank & Play
Use it to prank friends around you or just cure some boredom — endless creative combinations.
