This is a quick how-to on how to build yourself the easiest/quickest tunable stringed instrument in the world out of bits you probably have lying around your house.
The wire I used was from the inside of a washing line, however you can use a plethora of other types of wire/fishing line/old guitar strings etc.
The button is used to prevent the plastic lid from splitting, you can use buttons, or a nail, toothpicks, a pencil. Anything that will spread the tension of the wire so that the soft plastic doesn’t rip/tear.
If you or your kids or your class end up making one of these, I’d love to see the results!
