It works on the principle of a closed circuit. The moment Queaky senses that the circuit is closed meaning there is a loop for the current to flow, it gives out a shout. The tone is based on how much resistance is present in the circuit.
You can play music with Queaky with leaves on a tree, or a little water and a string, or even just with your fingers if you can master it. You can test different materials, use it to prank people around you or even just cure some boredom.
